Another useful advice for novice welders and self-taught garage workers. The disc on the grinder has worn off to the point where it is no longer possible for them to cut metal. We unscrew the clamping nut and throw out what is left of the disk, many do this, do not rush, see what benefit this worn-out disk can bring.
Now let's take this little disk and break it into several pieces. The very thing is to divide it into 4 parts. Who is not in the subject completely confused, why is this necessary? Look.
All discs have a certain thickness, it is accurate and is not only whole numbers in millimeters, but even tenths of a millimeter. For example, discs 1.2 mm, 1.6 mm, 2.5 mm, etc.
Therefore, these broken pieces of disc will be an excellent material for setting gaps in parts to be welded. We just make a spacer between the parts with these discs and grab the parts.
This photo is for example. Three pieces of a profile pipe with the help of pieces of discs from a grinder and a clamp, we can expose before welding, more precisely in front of the tacks, with absolutely the same even gaps. Now I will show a few photos from my work, when I used this method, method.
It was we who welded a structure for the transportation of bulk goods on a semi-trailer platform for a truck. When installing racks and sides, the structure was initially assembled on tacks.
In order to have an even, uniform gap for the normal operation of the sides in the future design, we simply use pieces of discs to catch and fix exactly such a gap in millimeters that we need.
So this is a free free material for a very useful and necessary operation in welding. Grab your arsenal of technical tricks!
