Abstract
PURPOSE: To prevent the burn-through of molten metal surface from the root gap surface by forming a cut-step part on the surface opposing to a vertical plate or horizontal plate, of a backing strip.
CONSTITUTION: An oblique cut is formed to the upper left corner of a backing strip 4' to form a pocket part 7a. Hence, the molten metal formed in the bottom of the groove is accumulated in this pocket part 7a and will not drop onto its back side. If the amount is large, the molten metal 9 subsequently flows forward so as to gradually fill the inside of the passage of the pocket part 7a extending in the weld line direction, cools in that portion, and solidifies in the state that it is held closely contacted with the vertical plate, whereby the blowing-through of the arc coming from later is prevented.
