What material is used to heat up after welding?
Then an old welder had resoldered it, and it was just the place. The main point is that the flame can't blow for too long, the alloy hair is red and it should be immediately with the matrix, not only faster but also more important. Because it's bad if you don't do it twice
Not only copper, but also a deoxidizer, and the most commonly used is the pine powder. There is also a certain level of operation, because I've seen a lot of welding common car knives, and the alloy head always falls off at work.
The dried hydroxide powder is insulated after the tool is welded. Calcium hydroxide, the chemical Ca (OH) 2, which is known as lime and lime, is a white powdery solid. Due to its small grain size, low density, low thermal conductivity, good thermal insulation, and low price, it is used in the welding of the lathe to insert the heat insulation directly. It can also be insulated with asbestos powder.
