する電縫管用誘導溶接機。An excitation coil is wound around the iron core as a primary winding, the iron core and the coil are insulated, and an induction coil assembly having a cooling water passage where both the iron core coil and the iron core coil are water-cooled is attached to a steel pipe material to be welded. Directly above the welding edge and facing the iron core so that the circumferential direction is perpendicular to the core, the induced magnetic flux generated at that time penetrates the material from the outer surface of the welding edge in the diametrical direction of the material, and the eddy current induced by this magnetic flux causes the material to An induction welding machine for electric resistance welding pipes, which heats the welding edges of the pipes to melt and pressure-weld them.
