Abstract
PURPOSE: To prevent the decrease in strength at the end part of weld by using the backing strip engraved with the grooves of the specific shape at the time of butting thin plates and welding the same while forming back beads on the back side.
CONSTITUTION: A backing strip 7 engraved with a parallel groove 8 of a depth h and tapered grooves 9, 9' of a length S is applied on the back side of the butt part of thin plates and arc welding is performed. It is desirable that h be made 0.5W 3mm and S 5mm or over. As a result, back beads are not formed on the back side owing to cooling effect in the portions where the thin plates make close contact with the backing strip and the convex form back beads are formed in correspondence to the depths of the grooves along with the progression of welding. Hence, the abrupt concave beads are not produced in the beginning end and terminal end parts of welding, hence nicking phenomenon is prevented and the weld zone free from any welding defect is formed.
