摘要： PROBLEM TO BE SOLVED: To provide a simple method for preventing stress corrosion cracking in a worked metal product.
SOLUTION: In a step of manufacturing a worked product by using the pressing, a blank 1 is formed by blanking a metal, and a stock 2 after the bumping is formed by performing bumping on both sides of the blank 1. The stock 2 after the bumping is drawn in a semi-cylindrical shape to form a drawn product 3, and a final cylindrical drawn product 4 is manufactured through a product working step. Stress corrosion cracking in the cylindrical drawn product 4 is prevented by exerting compressive stresses in the surface of the blank 1 by the pressing by bumping, and mitigating the residual tensile stress generated in the next drawing.

摘要： PROBLEM TO BE SOLVED: To unnecessitate cut-off work in a postprocess eliminating troubles at assembly of a motor core without deteriorating the characteristics of the motor by preforming recessed sections which are deeper than projections produced by laser-beam welding at the welding sections of core pieces. SOLUTION: A split stator core for each slot is manufactured by preforming recessed sections 3 having the shape of a relieving groove at the laser-beam welding sections 2 of core pieces 1 punched with a blanking punch and successively punching the core pieces 1. Then the core pieces 1 are welded to each other by irradiating the welding sections 2 with a laser beam. The recessed sections 3 have the shape of the relieving groove and depths which are deeper than the projections formed by the laser-beam welding and are provided on the internal side faces 5 of the core pieces 1 facing a rotor. In order to make the welds 2 have sufficient welded strengths, welds are usually provided on two sides of the core pieces 1 in a well balanced state, the inside-diameter side 4 facing the rotor and the outside-diameter side 5. Therefore, the gap between a rotor core and a stator core can be fixed and the characteristics of a motor are not deteriorated.
