PROBLEM TO BE SOLVED: To provide a welding technique for the steel bar with an anchor that eliminates restrictions in the size and shape of the anchor installed in the steel bar to be welded, that enables an excellent anchoring action in concrete to be obtained, and that has great operation convenience by allowing common use of a chucking means as is on a welding gun end. SOLUTION: On the end of a non-welding side of a steel bar 6 to be welded, there is provided a chucking margin L to install an anchor 12. Then, welding is performed for a base metal, e.g., an H-beam 8, with the steel bar 6 mounted on a welding gun 1 by the chucking means 5 through the chucking margin L. COPYRIGHT: (C)2007,JPO&INPIT |
