Abstract
PURPOSE: To seal a thick base metal efficiently, by sealing a root face of a butt edge by high frequency resistance welding and by welding a molten metal on the beveling of the root face by the submerged arc welding method.
CONSTITUTION: When high frequency resistance welding device 20 and submerged arc welding device 30 are installed along the welding line and steel pipe 1 is brought into the line and then the electric current is passed through contact 21 of high frequency resistance welding device 20, the contact part of root face 2 is heated by the resistance heat, and root face 2 is sealed successively from the end under a pressure applied by pressure roll 12 and a back wave is formed at the back side. When tab plate 40 is tack welded on the end of steel pipe 1 sealed at root face 2 and the electric current is passed through each electrode 31, 32 and 33 of submerged arc welding device 30, a molten metal is padded on the upper surface of tab plate 40, and, when sealed root face 2 of steel pipe 1 reaches this point, the beveling is welded by the molten metal.
