Abstract
PURPOSE: To achieve the improvement in the toughness of weld heat affected zone and welding efficiency by welding a pipe and pipe plate while cooling the same by the pressure air or the like from the circumference of a welding torch at the time of subjecting the pipe and pipe plate to TIG arc welding.
CONSTITUTION: The pipe 1 and pipe plate 3 belonging to a chemical apparatus such as methanol converter or the like are seal welded in a three o'clock welding posture. A welding torch 5 is made in double construction and pressure air, pressure carbonic acid gas or the like is jet out near the weld zone from the circumferential hole at the end of the outer nozzle 11 thereof, whereby the weld zone is cooled. Arc is generated between the welding torch 5 and the corner part of the end faces of the pipe 1 and pipe plate 2 and automatic welding is performed while the wedling torch 5 is being rotated along the circumferential direction of the pipe. According to this method, sound beads 9 are formed without becoming dropping beads. In addition, the weld heat effected zone 10 is suppressed of particle coarsening and the toughness is considerbly improved. Since the quantity of heat input may be increased, the considerably improvement in welding performance may be achieved as well.
