PURPOSE:To achieve welding with high accuracy, by performing cutting and welding of strips with the same welding head. CONSTITUTION:The rear end part of a preceding strip 1 which is clamped and held with a clamp 10 on an outlet side is cut with a welding head 9 and a cut scrap 7 is dropped. The cylinder 10 is tilted in an arrow B direction by a tilting cylinder 11 to deviate the rear end part of the strip 1 from the entrance path for a succeeding strip 2 and in this state a clamp 12 on an inlet side is advanced in an arrow C direction. The strip 2 is then clamped and held with the clamp 12 while the forward end of the strip 2 is in the position where the heat source of the head 9 travels. The front end part of the strip 2 in this state is cut with the head 9 and the cut strip 7 is dropped. The strip 1 is returned to the home position by the cylinder 11, and the strip 1 and the strip 2 are butted to each other, then both strips are welded with the head 9. |
