Abstract
PURPOSE: To captioned welding machine which is so constituted as to permit welding even in a narrow place around pipes by gripping the pipes being welding base metals only at one side of the fixing frame for containing said rotator and generating arc between the electrode mounted to the outside of the end face on the opposite side of the fixing frame and the pipes.
CONSTITUTION: Pipe gripping members 30, 30' and sealing members 39, 39' are opened and pipes 12 being welding base materials are set in the central position of a rotator 13 through notches 14, 15, after which the pipes are gripped by the members 30, 30'. In this state, only the open end of the rotator 13 having a gas release port 47 opens to the outside, in an internal spacing 49. Next, the sealing gas to be supplied 25 is jetted out 26 from outlet hole 29 upon starting of the welding machine to fill the space 49, after which it is released along the outside circumference of the pipes 12. On the other hand, arc is generated between the pipes 12 and electrode 41 by the high-frequency voltage to be applied to a non-consumable electrode 41, at the same instant of which the rotator 13 is rotated to perform welding of the pipe joint along the circumference of the pipes 12 by the electrode 41.
