摘要

The method for connecting ring area of a thin walled hollow shaft with a massive component through resistance welding, comprises selecting unusable parameters during welding and machinably removing welding beads emerging during welding based on unusable parameter selection as required. The partial area of the ring area is conically tapered and the ring area is completely tapered in section wise, trapezoidal or cascade manner. The wall strength of the hollow shaft is reduced in the area of the ring surface. The diameter of the hollow shaft is reduced or enlarged in the ring area. The method for connecting ring area of a thin walled hollow shaft with a massive component through resistance welding, comprises selecting unusable parameters during welding and machinably removing welding beads emerging during welding based on unusable parameter selection as required. The partial area of the ring area is conically tapered and the ring area is completely tapered in section wise, trapezoidal or cascade manner. The wall strength of the hollow shaft is reduced in the area of the ring surface. The diameter of the hollow shaft is reduced or enlarged in the ring area. The counter-surface of the ring area has a thickened area, which is produced through plastic deformation. In the thickened area, a centering groove is intended that corresponds to the conically tapered area before the welding process. The welding seam is subjected to an annealing treatment through a target current pulse. Both ends of the hollow shaft are simultaneously welded.
