PURPOSE:To quickly and surely weld a work by providing a welding head to weld a weld zone of the work so that it can move to a lower frame. CONSTITUTION:The work W cut in a desired shape is supported on a bottom die 9 born on the lower frame 3 and pressed and fixed by a top die 25 through the fall of a vertically movable upper frame 5. The work W is bent by a bending die 45 while a bending frame 49 is moved in a vertical direction. At least when the work W is inserted between the top die 25 and a bottom die 9, the welding head provided on the lower frame 3 is moved as far as the weld zone of the work W and the weld zone of the work W is welded by the welding head. In this way, the bent work W is welded quickly, surely and precisely without carrying itself. |
