Abstract
PURPOSE: To prevent welding defects such as mis alignment and to improve the efficiency of welding, by inserting a fitting pipe between two pipes and by arc welding its two parts as a filler metal with nonconsumable electrode.
CONSTITUTION: A pipe fitting 8 is inserted between two pipes 1, 1', and both the ring-shaped projection 9, 9' is fitted to the both end of the pipes 1, 1' and is fixed by clamps 11, 11'. Next, the position of electrode is set by a positioning clamp 12 fitted to a center projected part 10. Then, two position are welded by electrodes 13, 13' utilizing the projected parts 9, 9' as fillers. Before this, water-soluble gas dams 16, 16' has been inserted in the inside of the tubes 1, 1' and protective gas is applied to the inside through a tube 17 by a hole 15 or through a notch at the projected line part of the pipe fitting 8. After the completion of these joint welding, the tube 17 is removed from the hole or the notch, and the hole is closed by spot welding or the like.
