Abstract
PURPOSE: To make possible widening of weld bead widths with a small device of simple construction by providing cooling gas blow nozzles before and after a non- consumable electrode in its moving direction and flattening the arc in the direction rectangular to the weld line in the circumferential welder of stationary pipes by a TIG welding method.
CONSTITUTION: Cooling gas nozzles 17a, 17b are provided before and behind a non-consumable electrode 16 in its moving direction to cool the electrode and make an arc 18 in the flat shape in the direction rectangular to the weld line. Next, a plurality of filler wires 14 are supplied from forward of the moving direction of the electrode 16 and while inert gas is being supplied from the shielding nozzles, the welding torch is turned along the circumferential weld line of a pipe 5, whereby welding is accomplished.
