Title: Friction welding method for works made of different kinds of metals
Inventor: HASEGAWA TSUTOMU
IPC: B23K103/18
Filed: 2001-02-16
Abstract: PROBLEM TO BE SOLVED: To solve such problem that the area of end surface in the circumferential wall constituting a cylinder is small, when the neighborhood of an end surface to be friction-welded of a shaft work made of a high melting temperature metal is cylindrical, and then, only small joining strength is obtained in comparison with the case of the high melting temperature metal solid shaft work. SOLUTION: In a friction welding method, a space 11 constituted of the circumferential wall extended to the circumferential direction and a bottom surface 10 off-set at the deep side from the end surface 4, is arranged on the end surface of the metal made of the high melting temperature shaft work 2, and while keeping the pushing state of the end surface 14 of a shaft work 12 made of a low melting temperature metal against the end surface 4 of the circumferential wall, both shaft works 2, 12 are relatively rotated around the axes. The relative rotations are kept until the low melting temperature metal softened by the friction heat generated with the relative rotations is filled into the space 11 and becomes the pressurized state. In this way, both shaft works 2, 12 are friction-welded at their end surfaces and the works made of different kind metals can firmly be joined.
