PURPOSE:To perform satisfactorily welding of thin plates as well by constituting a titled jig in such a way as to permit changing of a clamping distance and setting the best value of clamping distance according to the thickness of the materials to be welded. CONSTITUTION:The left end part of a press plate 3a is pinned to the lower part of an arm 15a, and the upper part of the arm 15a is screwed to a ball screw 16a. The screw 16a is supported freely rotatably on a frame 17a, and the top end face of the frame 17a is attached to a stationary end. A handle 18a is provided at the left end of the screw 16a, and the position of a chip 8a can be moved to the right or left by turning manually a handle 18a to the right or left. The position of a chip 8b can be similarly moved to the right or left by rotating a handle 18b. Therefore, if the materials 2a, 2b to be welded are light-gauged, the clamping width (d) is narrowed by operating the handles 18a, 18b, whereby the welding defect occurring in thermal strain is prevented. |
