Abstract: A turbocharger wheel (4) and shaft (1) assembly exhibits a frustoconical geometry of welding zone contact surfaces extending to the outer circumference of the shaft (1). This frustoconical geometry not only allows continuous centering of the parts (1, 4) during joining, it also eliminates the problem of stress propagation along a plane. The location of the electron beam is shifted so that only the radially outer segment of the frustoconical contact surface is joined by welding, leaving a radially inner unmelted and unfused zone for maintaining firm contact of the oblique surfaces.

Abstract: To provide a turbine rotor which enables mass production with a low-cost apparatus and which capable of suppressing leaning of the rotor shaft after welding to improve the yield, while a turbine blade rotor 12 and the rotor shaft 14 are fit to each other with concave and convex portions 12a and 14a and are permitted to be rotated, laser beam L from a laser beam generating device 30 is applied to a joint face 16 along the circumferential direction to weld the welding portion. Then, laser beam L is polarized to temper a region X on the rotor shaft side containing the welding portion with laser beam L. In contrast to residual stress R1 having a local angular distribution generated during the welding, residual stress R2 is permitted to be generated over the entire circumference by tempering. Leaning of the rotor shaft 14 after cooling is thereby be suppressed.
