Abstract

PURPOSE:To improve efficiency and welding reliability by aligning a fixed pipe with a pipe to be welded by a piping aligning device to perform tack welding of piping by automatic welding equipment. CONSTITUTION:A cylindrical clamp 51 is fitted to the fixed pipe 1 so that the center of a window 54 for tack welding thereof comes to a welding groove line of the fixed pipe 1. Next, a mating cylindrical clamp 52 is fitted to the pipe 2 to be welded which is inserted thereinto with a tapered part of the inside of the clamp 51 as a guide and the pipe 2 to be welded is drawn near the fixed pipe 1 by a tightner 53 and the centering is carried out. The automatic welding equipment 60 is fitted to the fixed pipe 1 so that a welding torch 61 comes on the periphery of a welding groove 3 and the tack welding is performed from the window 54 for tack welding according to a predetermined program. After the tack welding, the piping aligning device 50 is removed and the main welding is performed by the automatic welding equipment 60. By this method, the tack welding by the manual welding can be eliminated.
