題がある。<Conventional technology and its problems> A conventional TIG welding machine for pipes has a welding head attached to the tip of a power cord connected to a welding power source, and the tip of this welding head has a split shape. It has a pipe supporting and fixing part that can be opened and closed, and the pipes to be welded are sandwiched and supported by this part, and the pipes are welded together by rotating a tungsten electrode in an inert gas atmosphere and generating electric discharge. However, with this structure, when attaching the pipe to the pipe support fixing part,
It is difficult to support the pipe in a state in which the welded end faces are accurately aligned, and the current situation is that the pipe is usually temporarily attached to the welding head by spot welding on the welded circumference of the pipe in advance. Furthermore, since the heat generated during arc discharge is cooled and dissipated by the welding head itself, heat resistance is required, and there are problems such as a limit to the number of times the welding head can be used.

In addition, when the pipe is fixed and supported, the pipe roundness forcing mechanism increases the roundness of the pipe and enables highly reliable welding, and the pipe welding support absorbs most of the cooling heat dissipation during welding. Since the receiver is held, the durability of the welding head main body is increased, and a case made of a heat-resistant resin material or the like can be used.
