Abstract

PURPOSE: To produce a pipe frame free from a sink on the pipe side during welding with a frame pipe and a joining piece having a projection matching the frame pipe placed on one electrode and energized under a pressure by the other electrode.
CONSTITUTION: A joining piece such as bracket and a pipe frame 2 are placed on a lower electrode 4 and energized under a pressure with the lowering of an upper electrode 1. At this point, as the pipe 2 comes in contact with a projection of the bracket 5 under a uniform surface pressure, the density of the current flowing through the each projection 10 is properly arranged thereby accomplishing an even projection welding. The projection 10 and the pipe 2 are fused together and with the lowering of the upper electrode 1, the outer cylinder surface of the pipe 2 is brought into contact with the innner cylinder surface of the bracket 5 under pressure. With such a method, a pipe frame of excellent quality for motorcycle or the like can be massproduced at a low cost.
