Abstract
PURPOSE: To make back weld penetration even by carrying out welding by flowing inert gas through a hollow, by forming a hollow route by butting groove faces mutually.
CONSTITUTION: Route surfaces 2 of groove faces of large-diameter pipes 1 and 1' are butted each other to form route 3. Next, while inert gas is flowed through route 3, arc 6 is generated by tungsten electrode 5 of TIG torch 4, thereby welding the both. At this time, the back penetration states of internal surfaces of pipes 1 and 1' are controlled by adjusting the feed amount of inert gas flowing through route 3.
