How to remove solder joints in bidirectional welding

Before welding, apply "talcum powder mixed with water" or "graphite powder mixed with water" to the area where welding slag will splash. Then, welding is performed. This makes it easy to remove. Save time and effort.

In addition, the method includes:

First, if there is only slight welding slag, wipe it with emery cloth or install a sand table with an angle grinder.

Second, it can be filed off with a file, but it is very troublesome, and there is no other tool for emergency use when the file is broken.

Third, polish with an air brush.

Fourthly, the grinder is used for grinding and is suitable for small workpieces.

Fifth, sandblasting machine or shot blasting machine, although this thing is not specially used to remove welding slag, the effect of removing welding slag is still good. In the past, we often used it to remove welding slag from stainless steel parts.

Double shielded welding is suitable for welding various large steel structures of low carbon steel and low alloy high strength steel. High welding productivity, good crack resistance, small welding deformation and wide deformation range, which can be used to weld thin and medium plates.
