Abstract: An end portion of a steel bar such as a reinforcing bar is planed at an angle to form a oblique tip surface having a prescribed angle for an arc welding. The end portion of the steel bar is fitted within a guide member comprising a butting tab that extends forward, guide edge portions that start from diametrically opposite sides of a base portion of the butting tab and extend backward from a position at a distance from a surface to which the bar is to be welded, but protrude further outward than the oblique tip surface, and a slit formed in the axial direction of end portions of the guide edge portions. An end portion of the butting tab is trimmed into an end shape in accordance with a surface to which the bar is to be welded and is butted against that surface. Weld beads are then built up in sequence from the inner surface of the butting tab and between the surface to which the bar is to be welded and the oblique tip surface at the end portion of the steel bar, to form a single weld.
