Welding is a process in which the materials of the workpieces to be welded (the same or different) are combined by heating or pressure or both, and with or without filling materials, so that the ma...
1.How to weld mild steel?
Low carbon steel has low carbon content and good plasticity, and can be prepared into various forms of joints and components. In the welding process, it is not easy to pr...
Electrode arc welding is the most widely used welding method in industrial production. The metal to be welded is one pole, and the electrode is the other pole. When the two poles are close to each ...
