About Welding Process

In the resistance welding method, a current is passed through a welded portion of a metal to be welded and the joint portion is heated by the resistance heat generated, in the meantime a pressure is applied to weld the metal.
Generally referred to as 'lap resistance welding' and 'resistance butt welding'.
Our company develops light electricity precision parts by using the spot welding technology base on lap resistance welding method.
