  • WELDING JIG DEVICE AND METHOD FOR PRODUCING PART
    Publication number: 20220134491
    Abstract: A device is used for forming a part by welding a plurality of members together, and includes a jig on one side having a joint face on one side, which is adapted to contact one of faces exposed on the outer surface sides of the plurality of members overlaid one on top of the other, and an opening on one side corresponding to a portion of desired welded portions of the part; a jig on another side having a joint face on the other side, which is adapted to contact another face of the faces exposed on the outer surface sides of the plurality of members, and an opening on the other side corresponding to another portion of the desired welded portions of the part and not corresponding to the opening on one side; a laser welding machine on one side that is configured to emit a laser beam toward the opening on one side; and a laser welding machine on the other side that is configured to emit a laser beam toward the opening on the other side.
