III. Order of the Ministry of Labor of Russia dated December 11, 2020 N 884n “On approval of the Rules for labor protection when performing electric welding and gas welding work” (Registered with the Ministry of Justice of Russia on December 29, 2020 N 61904)

general information

Proper organization of the workplace (welding station) is a prerequisite for the productive work of a welder. The better the workplace is organized, the more convenient it is for the foreman to perform his duties.

The welding workplace has many variations. A welder can work alone or in a team; he can always perform work in one place or be mobile. And the organization of space will depend on each type of work.

The following requirements apply to any welding station:

  1. The area allocated for the work must be sufficient not only for work manipulations, but also for the free movement of the welder himself.
  2. The workplace must be equipped with all necessary tools and work surfaces.
  3. The workplace should provide places for convenient storage of work items.
  4. The workplace must be ventilated and must also have a sufficient number of light sources.
  5. The welding station must be safe and fireproof.

This is a brief description of a standard welding location. Subsequently, these points are supplemented with other requirements provided for the performance of certain works.

Stationary welding station

The design of a stationary welding station involves the use of a protective cabin without a canopy.

Basic requirements for workplace equipment

  • Cabin area from 3 square meters.
  • The cabin walls are made of non-flammable materials.
  • The frame is made of metal.
  • The height of the desktop for sedentary work is 50-60 cm, for standing work – 90 cm.
  • There should be a tarpaulin screen at the entrance.
  • The total height of the cabin is from 2 meters.
  • Gaps for ventilation are left along the walls below - about 25 cm.
  • The area of ​​the working surface made of cast iron and steel should be one square meter.
  • Inside, the cabin is treated with a special fire-resistant solution of light gray color, which is capable of absorbing ultraviolet radiation and does not allow ignition.

Types of welding spots

Any preparation of a welder’s workplace begins with defining the work. What kind of work will the master do? Will it be manual arc welding, will he weld on a semi-automatic machine or use other equipment? After all, the workplace of an electric and gas welder will definitely be different from the workplace of an electric welder.


In this article we will talk about a welding place for an electric welder. At the moment, two types of welding places are organized for such work: stationary and mobile. A stationary place is used in factories, workshops and workshops, and a mobile one is used at construction sites, field work, etc.

After the installation of a stationary post, it remains unchanged for a long time. Only welding equipment, components, and worn-out structures are replaced. Simply put, a stationary workplace is a kind of “skeleton” to which other equipment can later be added, but the post itself remains in the same place.

Mobile posts are more flexible. They can be changed and transported many times by changing the set of equipment. Let's take a closer look at what requirements apply to these jobs.

Stationary workplace

A standard stationary welding position for a welder is most often used in large and small industries. The stationary workplace has compact dimensions (on average about 4 sq.m.) and can be located in the open space of the workshop or be separated by special noise-absorbing partitions.

Such a workplace is located permanently at the enterprise; it is not disassembled or transported. Accordingly, all equipment remains directly at the workplace, no matter what shift the welder comes on. At a stationary station, relatively small parts can be welded, since their size is limited by the size of the working area itself.

At a stationary workplace, the welder must have a comfortable table, chair, and storage space. Consumables should be stored in close proximity to the welding table so that the technician can quickly replace them during the work.

If the workplace is enclosed by partitions, special attention should be paid to its lighting and ventilation.

Mobile workplace

The main characteristic of a mobile post is mobility. Having completed such a workplace, you can take it with you and perform work outside the workshop. A mobile workplace is many times more compact than a stationary one. In most cases, it is a cart on which welding equipment and consumables are placed.

The mobile post does not have ventilation or special lighting, since it is often used outdoors, where there is natural exchange of air and sunlight.

The main disadvantage of a mobile post is the lack of protection from precipitation. If you have to work outside in the rain, you need to use a special canopy.

Equipment for different types of welding

The organization of welding stations is associated, first of all, with the parameters of the equipment being used. The main ones are weight and requirements for the power supply network.

The welding station must be equipped not only with welding equipment and accessories for it. In addition, additional tools are required for trouble-free operation of welding machines, and, if necessary, minor repairs. For uninterrupted operation, you will also need a certain supply of consumables: various types of additives, flux in powder form or inert gas.

Technological maps, individual regulations, diagrams, drawings and other documentation will help you assemble a workstation more accurately. It is customary to distinguish two large groups of common equipment: electric and gas.

Stationary posts focused on the use of electrical equipment are often equipped with powerful AC or DC devices. Power supply often requires a connection to a three-phase network. The most popular additional equipment: AC transformers complete with or without rectifiers, generators, electric arc stabilizers.

When work is planned using gas (inert or active), the package includes cylinders containing hydrogen, argon, helium or other gas necessary for work. For gas welding, you will need cylinders with oxygen and working gas - acetylene or propane. The stationary gas welding station can be equipped with cylinders of different weights, starting from 10 liters.

The table can be very massive or small and compact. The only condition is that the area of ​​the tabletop should not be less than 1 square meter. Vices and clamps will be its indispensable additions. In addition to this, additional equipment often includes various types of fasteners, pipe benders, rolling devices, etc. For mobile kits, small-sized equipment is used: gas welding machines with small cylinders, inverters and semi-automatic welding machines.

There are mobile installations located on the basis of automotive vehicles, including passenger cars. They are equipped with gasoline or diesel generators and are autonomous. Such posts are intended for field work. They are often found in natural disaster zones, on sections of highways after accidents; used in road and field work.

More about ventilation

Ventilation is one of the most important elements that must be taken into account when organizing a stationary post. This is especially true for those workplaces where gas is planned to be used. Ventilation is necessary to remove vapors generated during work.

When working at a stationary workplace, a huge amount of dangerous vapors and fine dust is generated. They negatively affect the health of the welder and in some cases can ignite or explode.

To avoid this, an air duct with forced ventilation is mounted above the work station. It works throughout the entire welding operation, and helps not only get rid of dangerous fumes, but also cools the equipment.

When working outdoors, special ventilation is not needed. Natural air movement is more than enough.

Table

For convenient welding operations, it is practical to place the product on the table. This increases the speed of welding and the convenience of welding in hard-to-reach places. The welder's table is made to individual sizes, based on the dimensions of future products. The legs must be height adjustable to accommodate workers of different heights.

The table should include devices for:

  • safe placement of the holder during the process of rearranging the product;
  • quick access to consumables and easy electrode change;
  • location of tools (hammer, file, flashlight, slag separator, metal brush);
  • ignition of the electrode on the rough surface;
  • installation of non-standard structures with protrusions in special holes.

Additional Information

Organization of the welding place is important, but the rules will only work in conjunction with the correct selection of equipment and welding tools. We will give a couple of recommendations regarding welding clothing, a helmet, wires and a holder. This is the minimum set of tools for a welder, not counting the welding machine, of course.

Protective clothing and mask

Protective clothing and footwear are essential for any welder. If you do not use protective equipment, not a single welding station will help you. Even well stocked.

The welder must wear a special work uniform (trousers and jacket), gloves, and shoes. Clothing must be made of non-flammable materials that are resistant to stains. Shoes should not conduct current. Also, clothing must be resistant to molten metal.

A mask is necessary to protect your eyes, hair and skin. Welding work without a mask is prohibited. The mask must be equipped with a light filter that protects the eyes from radiation. Its weight should not exceed half a kilogram, otherwise the master will quickly get tired of constantly wearing a mask on his head.

We have previously talked about masks, read about it here. We recommend choosing chameleon masks in the mid-price category or above. They are great for regular work and do the job well.

Welding wires

The welding wires also need to be chosen correctly so that they do not cause a short circuit or fire. The better the cable insulation, the higher its strength and reliability.

Pay attention to the workmanship and wire cross-section. If the cross-section is too small, the cable will not be able to withstand the load and will melt, which can lead to dire consequences. However, you should not choose cables with excess cross-section, since they are quite expensive and inconvenient to carry, store and use.

When organizing a welding workplace, make sure that it has a separate place for storing various cables. They should not constantly get tangled and dusty. They also need to be placed closer to the master, but away from explosive substances and materials.

Electrode holder

The correct organization of the workspace also depends on the “holder”. It must be easy to use so that the master can work productively. If you purchase a low-quality holder, all the convenience of the welding station will come to naught.

Any welding place must be equipped with several welding holders. Firstly, for their prompt replacement if necessary, and secondly, for performing various welding works.

When choosing a holder, make sure that its weight is not too heavy, but not too light. You should not experience constant arm fatigue from using a heavy holder. But at the same time, too light a holder can reduce the accuracy of the work. Select the tool individually.

The handle of the holder should be made of rubberized material. It should be easy to grip and not allow current or high temperatures to pass through. If the handle gets hot, the welder can feel it even through protective gloves.

The electrodes should be tightly attached to the holder and not “walk” from side to side.

For holders you need to provide a separate place in which they will be stored. It should also be close enough to the master’s hand so that he does not have to waste time searching for the right tool.

Welder clothing

The welder's suit is made from specialized fire-resistant fabric, which is designed to protect the specialist from sparks and splashes of molten metal and does not melt from contact with heated surfaces, which eliminates burns.

Moreover, the welder has no right to perform any type of fire welding work without a protective set of clothing, the list of which includes:

  • Actually the welder's suit itself, which complies with the required GOST.
  • Special shoes resistant to the thermal effects of sparks and steel splashes.
  • Work mittens or gloves, mostly made of canvas.

Purpose of equipping the welder's workplace

Organization of a welder’s workplace is a procedure that provides for the provision of the most favorable conditions for welding. One welder or a whole team can be responsible for a section. Among the features the following points can be noted:

  1. As a rule, a certain area located in a structure or at the site of construction and repair acts as a welder’s place.
  2. When considering the requirements for a workplace, most attention is paid to the fact that it must be equipped with the required tools and equipment.
  3. Preparing the work area also includes removing unnecessary items that could compromise welding safety.
  4. The organization is carried out taking into account the size and type of structure being processed. Particular attention is paid to ensuring that the welder or assistants do not have to fix the workpieces. This is prohibited by accepted safety precautions.

Schematic illustration of a welder's cabin

In general, we can say that only with proper organization of the workplace in accordance with safety precautions can welding be performed efficiently. This takes into account the welding location, environmental conditions and many other points.

Types of ventilation systems and arrangement rules

An exhaust hood for a welding station, installed according to the rules, can significantly reduce the concentration of hazardous substances in the atmosphere and minimize harm to the environment. The type and power of fans, as well as the routing of air ducts, are selected taking into account the number and location of places for welders. Exhaust structures can be placed on the roofs of workshops or near them; the air intake should not be located in the area for the emission of polluted air.

Local

The welding shop or workshop has local and general exhaust

When creating a local type hood, the ventilation of the posts is selected taking into account the size of the elements being welded and the intensity of the work. The amount and composition of the gases formed depends on these nuances. Thanks to the simple design and design, the productivity of such a system reaches 5.5 thousand m3/hour. During welding and surfacing of large products on tables not equipped with devices, welding aerosols are removed using suction from mobile units with filtration ventilation. For some types of work, it is advisable to use lift-and-swivel hoods. Their design includes a flexible hose with a diameter of up to 200 mm, mounted on a console and directed to the desired area. The receiving pipe is placed at a distance of 7-8 meters from the worker.

General exchange


Exhaust fans at welding stations

The general exchange type system includes injection and exhaust fans, as well as air ducts equipped with filters and adjustable supply structures. Such ventilation is designed to provide fresh air to all areas of the workshop and reduce the content of harmful impurities in the atmosphere. It is worth choosing if more than 200 g/hour of electrodes per 1 m3 of the total volume of the room is used during the work. Otherwise, the influx of air masses will be provided naturally.

In winter, outside air is supplied to the workshop at a temperature not lower than +18 degrees. General ventilation for the welding station must be supplemented with filtration elements that purify the air before being released into the space. The performance of the devices is selected to ensure a 10-fold air exchange. The vertical speed of movement of air masses is maintained at no lower than 0.1 m/s. This value is sufficient for mixing media and eliminating welding aerosols from areas outside the posts.

Inside closed and semi-enclosed spaces


To organize a ventilation system inside a closed or semi-enclosed space, there are several available schemes.
In the workshop, you can create an organized air exchange in one container, where clean air will be supplied from outside. Next, the air masses are removed mechanically due to the combined action of inflow and exhaust. The second method involves removing contaminated masses near electric welding arcs; there is also a third option, which involves ventilating only the worker’s breathing zone by supplying clean air under the shield. The most common type of system is a tank ventilation scheme using a supply jet, which involves the installation of flexible hoses and high-pressure fans. The main advantage of this method is the supply of clean and heated air from the street during the cold season. Tanks in this arrangement are located in specially designated areas. To determine the volume of supplied air, its speed in the work area should not exceed 0.7-2.0 m/s for manual welding. You can avoid the entry of polluted air into the workshop by installing the mass supply from the opposite side.

What are the locations for welding work?

Safety precautions and many other regulatory documents determine the classification of the workplace into several types. An example is the information below:

The first type is most often associated with special premises in workshops, the second - mobile ones, required for traveling to the site of an accident or construction. The welder's cabin is equipped only once in accordance with safety regulations, after which attention is paid only to the technical condition of critical mechanisms and structures.

What is a welding post and what does it consist of?

A welding station is a specially designated place for a welder where he can perform work related to welding metal products. There are several types of welding stations; they will be discussed below in this article on welding from the website mmasvarka.ru.

The welder's place or welding station has all the necessary tools and equipment. The area of ​​the stationary welding station must be at least 6 square meters. m. The welder's workplace must be comfortable, fireproof and have good exhaust ventilation.

Stationary workplace

A stationary welder's position is found in various production workshops. They are suitable for welding small products. Among the features of equipping such premises, the following points can be noted:

  1. If the premises are properly equipped, unhindered access to workpieces is ensured.
  2. Explosive and flammable substances should not be located nearby.
  3. When using inverters that operate on flammable substances, cylinders should be located away from open flames.
  4. Unobstructed access should be provided to consumables, for example, electrodes and wire. This is due to the fact that during welding you need to quickly change some elements.
  5. The stationary location is prepared taking into account exactly which elements will be welded together. Safety precautions require that the welder's workplace ensures that the workpieces remain stationary during processing.

Stationary welding station

Training is carried out by following specific instructions, which are developed by an employee of the organization.

Mobile post

A mobile place can be created for a gas and electronic inverter. It is worth considering that a welding cabin is required for its installation in case of high ambient humidity.

The fewest problems arise when using gas welding. This is because electrical equipment must be reliably powered.

Welding wires: purpose, recommended cross-sections

The organization of the welding station involves the use of a cable of the most suitable cross-section. This indicator should be taken into account for the following reasons:

  1. If the cross-section is too small, the cable cannot withstand the load and begins to overheat. As a result, heat acts on the insulation, causing it to melt. If the damage is severe, a short circuit may occur.
  2. Large cables are expensive. At the same time, they are less practical to use; transportation and storage creates many problems.

Cable selection is carried out in accordance with regulatory documentation. The organization of the welder's workplace is carried out taking into account the fact that the cables should not be intertwined, all contacts should be fixed. Cable and other electrical equipment should not be located near flammable materials or water.

The optimal cross-sections of the welding wire are presented in the following table. As previously noted, the choice of wires is selected depending on the power of the equipment used by the welder. The optimal indicator is selected in accordance with the table.

Table of cable cross-sections depending on power

Using tabular data allows you to avoid quite a lot of problems. A high-quality cable has effective insulation, which eliminates the possibility of a short circuit.

Holder

The welder's main tool is the holder. Productivity and quality depend on its convenience and thoughtfulness. The holder can be of two types: to clamp the electrode like a clothespin, or to tighten it by twisting the handle. Regardless of the type, it should allow the electrode to be changed in 4 seconds.

The structure is well insulated to prevent electric shock. The cable and the holder itself constantly exert their weight on the welder’s hand. Therefore, the mass of these elements should be minimal so as not to overwork the welder and not limit movement.

If work is carried out at high current (from 500 A), then the holder is equipped with a protective pad that prevents the welder’s hand from being damaged by high arc temperatures. When the welding current exceeds 600 A, the cable is passed to the electric holder, bypassing the handle that the worker grasps. The sides that secure the electrode are subject to the adhesion of molten metal splashes, making it difficult to replace a new consumable element. This slows down the entire process and the welder gets tired faster. To prevent this effect, the surface of the holder on which drops of metal fly is lubricated with a scraper and cleaned at the end of the day with a needle file.

How to choose an electric holder

When organizing your workplace, you also need to choose the right electrical holder. How safe the workplace will be and what labor productivity will depend on its technical condition. The welding station can be equipped with several types of holders, it all depends on the type of work being carried out.

When choosing such a device, pay attention to the following points:

  1. Weight should not be more than 0.5 kilograms. Excessively heavy versions complicate the welder's task. When welding for a long time, your hands will get tired, which will ultimately reduce your productivity.
  2. Attention is paid to how comfortable the grip is. To prevent the handle from slipping, its surface is often grooved.
  3. During operation, the structure should not become very hot. Otherwise, problems may arise during prolonged welding. Although the welder must use special gloves, high heat causes significant discomfort.
  4. The surface must be insulated, since such an element should become a barrier to electricity in the event of a malfunction. When organizing the workplace, attention is paid to the quality and integrity of the insulation.
  5. The fastening of the electrodes must be strong, since at the moment of contact with the surface they are subject to mechanical stress.

It is recommended to purchase original electrical holders recommended by the manufacturer for organizing the workplace. Before each work, the condition of the structure is checked.

Create your own post

You can organize your workspace with your own hands. When creating a mobile welding station, additional components are required to carry tools and consumables.

Collection of tools and materials

When organizing a welder’s workspace you will need:

  1. Current supply devices. These include transformers or generators, often operating from a 380 V network.
  2. Cylinders with inert or active gas. Large capacity containers are installed at stationary posts.
  3. Set of fixing tools. These include vices and clamps.
  4. Means for pre-processing of metal parts - cold rolling and rolling devices, pipe benders.
  5. Inverters, semi-automatic welding machines for mobile posts.
  6. Electrodes, filler wire. It is recommended to purchase different types of materials.

We recommend reading: How to cut metal edges for welding

How to assemble

In the process of creating a welding booth with your own hands, follow the following rules:

  1. The recommended length of the working area is 2 m, width – 2.5 m. The ceiling height should be at least 2 m. The upper part of the office should not be closed.
  2. To assemble the walls, sheet steel or plywood treated with a non-flammable composition is used.
  3. For preliminary preparation and welding of metal parts, a convenient welding table is organized. It can be made stationary or foldable. For assembly, profile pipes and thick steel sheets are used. Tables must be equipped with metal holders that secure the current-carrying cable and grounding wire coming from the power source.
  4. Containers for storing electrodes and welding wire are placed on the side of the table. Drawers are installed in which small tools and technical documentation will be stored.
  5. Install single or multi-station arc power sources. The first option is preferable when organizing your workspace yourself. In the second case, the use of current-carrying busbars will be required.
  6. Install a switch to control the welding current.

Device in stages

A welding room can be set up in a garage, at a production site, or at a technical inspection station. In this case, the following scheme of work is used:

  1. Choose a place. It is recommended to locate the post away from flammable liquids, materials and gases.
  2. Assembling the cabin. From the floor to the bottom edge of the walls, leave gaps of 5 cm for ventilation. When working with inert gases, this distance is increased to 30 cm. Ventilation meshes are installed. A tarpaulin or plastic non-flammable screen is hung at the entrance.
  3. Mount a table with a tabletop. Provides the ability to adjust the height of the racks and the area of ​​the tabletop.
  4. Install lighting fixtures.
  5. The cabin walls are painted with light gray paint that absorbs ultraviolet rays. Choose paint compositions based on titanium or zinc.
  6. Install a forced-type exhaust system. Connect the equipment to a centralized air exchange system.
  7. The floor is poured with concrete. Brick can be used to form flooring.
  8. Install a switch for emergency shutdown of welding machines.

At the last stage, connect the equipment to power sources.

Electric welder mask as a means of protection

Safety precautions for organizing a place for welders include the use of special shields and a helmet. When manufacturing them, the standards established in GOST 12.4035-78 must be taken into account. Among the main standards we note the following:

  1. The structure should not be heavier than 0.5 kilograms. Otherwise, it will be difficult to carry out the work.
  2. In order to protect the eyes, light filters are installed. They are divided into 13 classes, the choice is made depending on the power.
  3. When choosing a mask, attention is paid to ensuring that it fits comfortably. From time to time the welder has to open it for visual inspection of the seam.

There are a wide variety of protective masks available on the market. More expensive versions are characterized by greater efficiency. If you frequently carry out welding work, it is recommended to purchase a high-quality product, since ultraviolet and other radiation can be harmful to health.

Ventilation requirements

It is necessary to pay attention to the efficiency of ventilation when organizing the place, especially when working with a gas apparatus. Its purpose is to remove warm air and supply cold air, which is required for cooling tools and equipment.

During operation, quite a large amount of toxic gases can be formed. At high concentrations there is a risk of poisoning. If the concentration of gases is high, then there is a possibility of their detonation.

As a rule, artificial ventilation is represented by air ducts that supply and discharge air. To improve operating efficiency, a fan is installed. Problems with equipment cooling and gas pollution practically do not arise when work is carried out outdoors.

Ventilation

When using gas in the welding process, it is necessary to ensure good ventilation of the room.

Ventilation is needed for several reasons:

  1. To reduce the concentration of toxic substances that may be released from the metals being welded . When carrying out welding work, various harmful impurities can be released into the air: carbon monoxide, nitrogen monoxide and fluoride inclusions.
  2. In order to remove gas contamination from the room , which can lead to detonation.
  3. To ensure cooling of working tools and equipment that overheats during operation.

Ventilation can be natural, which is carried out using air flow from the street, as well as artificial. For artificial ventilation, special hoods, fans and other means of air circulation are used.

Exhaust ventilation is designed to remove harmful gases from the room as much as possible, while supply ventilation is designed to compensate for organized exhaust by diluting substances to acceptable working concentrations for health.

The best option for a welder's workbench is one that is equipped with dust extraction directed downward or to the side. The effectiveness of the suction of harmful substances from the inhalation zone is ensured by the close location of the exhaust intakes to the arc site.

Requirements for special clothing

Special clothing can be considered personal protective equipment. It is manufactured taking into account the characteristics of metal processing, as well as the possible impact. The kit includes:

In most cases, they are made using tarpaulins to which asbestos is added. Due to this composition, the surface becomes much more resistant to the ingress of molten metal.

Advantages of welding curtains

Special curtains are very popular. They make it possible to significantly simplify work and divide the site into several sectors. The features of such equipment include the following points:

  1. Fire-resistant fabric is used in production.
  2. The material used can also withstand minor mechanical stress.

Variety of welding curtains

There are several versions of such equipment, each characterized by its own characteristics.

Solid standard curtain

Most often, a continuous curtain is installed. It is represented by a solid material that is attached to special load-bearing elements. Among the features we note:

  1. Visual protection and blocking ultraviolet radiation.
  2. Protects the environment from splashes and molten metal.
  3. The negative impact of side air flows is reduced.

Solid standard curtain

When choosing the most suitable curtain, attention is paid to the width of the seams, the thickness of the material and some other points.

Strip welding curtain

The protective curtain is selected taking into account various parameters. The main ones can be called:

  1. Thickness and type of material. Some fabrics are characterized by increased resistance to temperature.
  2. High-quality versions are stitched.
  3. Type of supporting structure.

Strip welding curtain

Such protection can be installed quickly; after the process is completed, it is quickly assembled. The supporting element is made of corrosion-resistant metal.
