Abstract
PURPOSE: To form welded joint part excelling in joint shape and strength, by placing a joint pipe of the same aperture and same material between the pipes to be welded, and welding the joint at two positions using the fitting part thereof as the filler metal, when butt-welding the pipes by nonconsumable electrode arc welding method.
CONSTITUTION: When butt-welding pipes 1, 1', the both pipes 1, 1' are connected together by means of a joint pipe 7 of a short width having the same aperture and material as the pipes. At both ends of the joint pipe 7 are provided ring projections 9, 9' which are to fit to the end outer edges of the pipes 1, 1' so as to connect with the pipes 1, 1'. In the central part of the pipe body 7 is formed a ring projection 10 for determining the welding position, and the position of electrodes 13, 13' is set by a positioning clamp 12. The both pipes 1, 1' are secured with clamps 11, 11', and arc welding is performed by using the projections 9, 9' as the filler metal. Thus, a welded joint having normal joint shape and excellent strength may be obtained.
