Abstract
PURPOSE: To heighten the efficiency of the tack-welding process, and to manufactur the large diameter pipe with good deposite metal condition, by welding the tab plates to four corners of the rectangular steel sheet before the 0-press process, by tack- welding the steel sheet after being pressed into 0-type, and by cutting away the tab plates after the main welding is finished.
CONSTITUTION: The tab plates 2 are welded to four corners of a rectangular steel sheet 1, whose circumference is then finished by the edge planer. Following to this, C-press, U-press, and O-press are carried out, and then, the automatic tack-welding is cairried out over the entire length of the weld zone 1C, and further, the main welding is carried out from outside and inside. Next, the tab plates 2 are cut and removed away. The thickness (t) of the tab plate 2 is taken as t=T±3mm when the thickness of the steel sheet 1 is T>19mm, and t=T±2mm for T<19mm.
