Welding Machines

Welding machines melt and integrate two or more metallic members by applying heat or pressure.
Welding machines are used in applications such as automobile body welding and spot welding, where a bond is created by crimping metal and feeding an electric current through it so that the metal melts and joins due to the resistance heat.
