Abstract

PURPOSE: To eliminate complicated after-treatment by usual method and to obtain good weld zone, by applying high energy density welding and arc welding on the groove having 10W30mm of root face at the same time and softening in a specific extent, on occasion of carrying out composite welding of thick steel materials.
CONSTITUTION: At the time of carrying out seam welding of butt part carried out UO press processing, using steel material having more than 40Kg of hardness, hardening by high energy density welding, the groove shape is made (A)W(F) and for example, on occasion of the shape (D), the depth root face x is made 10W30 mm (a fixed softening is difficult at more than 30mm and merit of this invention is not exhibited at less than 10mm) and groove depth y1, y2 is made about 30mm. At first, the high energy density welding is carried out against x face and next, arc welding is carried out against y1, y2 faces by annexed list condition and then, weld zone of the above hardened x face is softened at Hv≤300. Thus, complicated after-treatment by usual method is made unnecessary and good weld zone suitable for high pressure thick steel tube, is obtained.
