ERW Welded Pipe Manufacturing Process

In ERW welding, two electrodes, usually made from copper, are used to apply pressure and current. The electrodes are disc-shaped and rotate as the material passes between them. This allows the electrodes to constantly contact the material to make long continuous welds.


A welding transformer supplies low voltage, high current AC power. The joint of the pipe has high electrical resistance relative to the rest of the circuit and is heated to its melting point by the current. The semi-molten surfaces are pressed together with a force that creates a fusion bond, resulting in a uniformly welded structure.
