Abstract

PURPOSE: To prevent the occurrence of the captioned cracking by inserting a thin strap between the base metals of the backing strip joint part and backing strips.
CONSTITUTION: Backing strips 3, 3' are positioned slender in the joint direction on the back side of the one side butt welding face of base metals 1, 1'. In the butt portion of the backing strips 3, 3', a thin strap 4 whose top outside circumference is beveled 4' to taper form and whose width is approximately the same as that of th backing strips 3, 3' is so inserted between the base metals 1, 1' and backing stips 3, 3' of the backing strip joint part that it lays across both ends of the backing strips 3, 3'. After the discontinuous parts of the backing strip joint part is repaired, the one side butt welding face of the base metals 1, 1' is welded.
