PROBLEM TO BE SOLVED: To provide a jig for welding over parts in which the manufacturing man hour is reduced by reducing the number of actuators, and the parts can be easily drawn after welding. SOLUTION: Upper and lower shells SL, SU are almost overlapped and abutted on sunk surfaces 36, 46 of first and second press dies 30, 40, and abutted on the second die and the first die by operating actuators. The upper shell is pressed by an upper outer side receiver 45, and the lower shell is pressed by a lower inner side pressing plate 55 fixed to the second pressing die and moved on the sunk surfaces. The lower shell is held by a lower outer side receiver 35 and the lower inner side pressing plate 55, and the upper shell is held by an upper inner side pressing plate 50 fixed to the first pressing die and the upper outer side receiver 45, keeping the specified positional relationship. When the second pressing die is released after the welding, the upper and lower inner side pressing plates are also released from the inner side, and a product can be easily released.
