<P>PROBLEM TO BE SOLVED: To provide a method of forming a welding connection part of a joining member, by which the loss amount of a required material is reduced and a projection part for preventing buildup of a deposited metal is easily and inexpensively formed in a joining member, when manufacturing the joining member to be butt-welded. <P>SOLUTION: By not forming the projection part of the joining member by shearing but forming the projection part at the welding connection part of the joining member by compressing, a notch margin of the material required in shearing is eliminated, and also the need of beveling of the projection part is eliminated. <P>COPYRIGHT: (C)2013,JPO&INPIT |
