Abstract

PURPOSE: To prevent weld defects when a box pillar is manufactured by the electroslag welding of a plate of 20mm or less in thickness with a consumed nozzle, by providing a welding gap of prescribed cross-sectional area between the plate and another welded member and inserting the consumed nozzle into the gap.
CONSTITUTION: Backing pieces 8, 8' are welded to the plate 4 of 20mm or less in thickness. The electroslag welding gap 3 is provided between the end face of the plate 4 and the contact surface of another plate 2 so that the width of the gap on the contact surface is 25 to 30mm and the length of the gap is 25mm. Therefore, the cross-sectional form of the gap is trapezoidal. When the thickness of the plate 4 is 20mm, the minimum cross-sectional area of the gap 3 is 562mm2. The consumed nozzle 6 is inserted into the gap to perform the electroslag welding to manufacture the box pillar. Even if the nozzle 6 is curved into contact with the welded members due to the winding tendency of welding wire, the weld defects such as slag inclusion, incomplete penetration, etc. are prevented.
