Abstract
PURPOSE: To enable persons having no high degrees of welding techniques to perform easy and highly efficient welding is well by forming a positioning/holding device for metallic pipes to be butt welded into the specific construction by which the pipes are held respectively freely rotatably and axially pressably.
CONSTITUTION: In order to weld metallic pipes 1, 2 with a welding device for metallic pipes, particularly, Al made thin-walled pipes, a pipe 1 is placed between a pair of receiving rollers 4, and the right end part of a pipe 2 is inserted into a holding/pressing device 7. A retaining roller 5 is lowered to press the pipe 1, and the pressing force thereof is such that when a roller 4 on rear side (on the rear side of the figure) revolves the pipe 1 is revolved by the friction force of said roller and the pipe 1. Thence, a piston rod 6a is advanced to the right by a cylinder and the device 7 is advanced to the left to press and butt the pipes 1, 2. The device is so adjusted that the butted parts come to the welding position below a torch 8 and the leading end of a filler metal supply device 9. The butt pressing force is set at the force by which the revolving force of the pipe 1 is transmitted to the pipe 2 by the friction of the end faces, and welding is carried out.
