Study of safety operation of AC resistance spot welding system
This type of welding machine is a single-phase AC RSW machine. In practical welding operations, the firing angle α of each SCR is one of the most important input variables of the RSW electrical system. It decides the amount of energy delivered into the welding system and all the control performances of the system.

Resistance Welding Guide
What is Resistance Welding. Resistance welding is a group of thermo-electric processes in which coalescence is produced by the heat obtained from resistance of the work to electric current in a circuit of which the work is a part and by the application of pressure. Said another way, pressure is applied to the two overlapping sheets being joined.
