ABSTRACT Structure for and a method of resistance welding using an induction coupled power source. The structure of the invention comprises an electric coil wrapped around a flux concentrating core in close proximity to members to be welded together, a source of alternating electrical energy connected through the coil and means for applying pressure between the members to be welded. In accordance with the method of the invention the members to be welded are heated by at least one of an induced current and hysteresis loss and the heated members are then forged together by applying pressure thereon. The weld effected by the method of the invention may be either a spot weld or a continuous weld. Further in accordance with the structure of the invention the flux concentrating core may be on one or both sides of the materials to be welded and may be linear and perpendicular or at an angle to the members to be welded, or may be U-shaped or cup-shaped including a central post around which the coil is wrapped.
