PURPOSE:To suppress the bending of a stator by welding a butting portions of a housing, and then, or simultaneously with welding applying heat of the prescribed amount less than the welding heat of the butting portions to the opposite side. CONSTITUTION:An iron plate is bent in a cylindrical shape to form a housing 1, a stator core 3 is inserted into the housing 1, and positioned. After clamped by a jig 4, the axial butting portions 2 are welded directly by a welding torch 5. Then, the stator is rotated at 180 deg., and heat of the prescribed amount less than that applied to the housing 1 by welding is applied by the welding torch 5 to the opposite side of the stator rotated at 180 deg.. The amount of the heat applied to the opposite side is suitably 20-30% of that applied to the housing 1 by welding. |
