Abstract
PURPOSE: To obtain the annular worked body free from defects such as cracking, necking and crazing by forming the butt end faces of a metal plate formed to annular blank to the specified shape and flash butt welding the end faces then subjecting the same to weld flash planing and roll forming.
CONSTITUTION: One sheet of high tensile steel plate blank 10 is prepared and is formed to a parallelogram whose both side parts 10a, 10b are formed to the sides inclined by an angle θ from the straight line perpendicular in the lengthwise direction. After this is bent to a cylindrical shape, the butt surfces are flash butt welded to make a cylindrical blank 12. Next, the welding flash is removed by planing to make an annular blank 12', after which the planed portion 13 inclusive of the weld line is formed, and the blank is subjected to roll and expansion forming. In this way, the annular worked body 14 which is suited for disc wheel rims of desired shapes for vehicles, etc. and is free from defects such as cracking, necking and crazing, which are unavoidable with conventional methods, is obtained.
