Metal sander cleaning welding seams with grinder

Article updated and supplemented: August 11, 2021

The welding process is based on the formation of a permanent connection between parts by heating them. After the formation of a molten weld pool, structural changes occur in the material. Due to external energy, the atoms occupy a new stable position in the crystal lattice.

The welding procedure is accompanied by the formation of a weld seam. If the technology was carried out incorrectly, then this place will be weakened in the design. High-quality cleaning of seams after welding eliminates possible negative consequences.

IRomanoff › Blog › Abrasives I use.

Hi all! I was once reproached for using materials and working methods that a “mere mortal” should not know about. They say this is the lot of professionals, not garage craftsmen. I categorically disagree with such statements and believe that any person with access to the Internet can and should be aware of the state of affairs in those areas that interest him.

However, I decided to group in one place information about the minimum of materials and related devices that are simply necessary for body repair. I’m not talking about the painter yet, we will talk only and exclusively about the tin.

So, what kind of abrasives and tools do I use when working on the Bucket and why.

0. I try to use 3M abrasive materials - extremely high quality, brutal efficiency and durability at a considerable price. However, the material consumption is so insignificant that you can simply forget about the price. Therefore 3M.

1. First of all - adapters. They are needed to attach consumables with a Roloc mount to the tool. I use an adapter with a diameter of 75mm and M14 thread for an angle grinder and a spindle adapter for a drill. They look like this:

In fact, these are the main investments when starting to work with 3M - each costs about 800 rubles, but is purchased once for a lifetime.

2. Cleaning discs for an angle grinder, 75mm in diameter:

There are different ones for working on different materials, while the abrasive for stainless steel, non-ferrous metal and steel is different. The grain size, of course, varies greatly depending on the task. My interest in them is cleaning weld seams, so the grit size is 60+. The photo shows the latest discs with “Cubitron 2” abrasive - they cut extremely aggressively and are about three times more wear-resistant than “regular” discs. Cost - about 80 rubles / piece.

3. Scotch Brite grinding wheels for grinders, 75mm in diameter:

The main purpose is to remove paint and other coatings. The efficiency is brutal, it’s simply stupid to compare with wire brushes. Anti-gravel and protective coatings are torn off from the bottom simply playfully, without the use of force or violence to the instrument. The metal tinder is very light, almost barely scratching - great for finishing weld areas where repairs should not be visible. Cost - about 100 rubles / piece.

4. Scotch Brite grinding disc for drill. Diameter 100mm, thickness 13mm, can take the shape of complex surfaces (such as an internal corner at a corner):

The application is the same - stripping paint and anti-gravel. Wear resistance when used correctly is very high - it took one disk to cover the entire underhood of the Bucket. Cost - 650 rubles/piece.

With this simple set you can almost completely cover the issues of cleaning during auto repair. The only caveat is that Scotchbrites deteriorate from contact with the bitumen so beloved by our collective farmers. This is understandable - no one in their right mind has been pouring bitumen on cars on purpose for about 50 years now.
