Abstract

Provided is a lap seam welding apparatus (10) for seam-welding steel strips (18), which are individually cut by a shearing machine (21), by lapping the steel strips (18) partially and by feeding a DC power source (12) capable of controlling an electric current at the welding time. The lap seam welding apparatus (10) is equipped, separately of a welding circuit (15), with a demagnetizing circuit (17) for demagnetizing the shearing machine (21), which has been magnetized by the welding current, at a non-welding time with the power source from the DC power source (12). The demagnetizing circuit (17) removes the residual magnetism of the shearing machine (21) magnetized by the DC current at the welding time.
