PURPOSE:To reduce a thermal influence on frames, by fillet-welding the end sections of laser-welding sections between struts and the frames, locally. CONSTITUTION:A leg section 4 is fitted on the lower section of the drum section 3 of a rotary electric machine. The leg section 4 is composed of a base 8 and struts 9, and is connected to the drum section 3 at laser-welding sections 15. The end sections 17 of the laser-welding sections 15 are filling-fillet-welded so that the corner sections of the struts 9 may be locally wound up. The filling- fillet-welding is generally performed with MAG-arc-welding. The linear section of the welding is short, and so a thermal influence is small. |
