  • Welding method, welding system, and welding jig for robotically welding a motorcycle fuel tank
    Publication number: 20090206146
    Abstract: A welding jig for holding a motorcycle fuel tank when the fuel tank is welded includes a plurality of attachments for holding said fuel tank through resilient bodies. The plurality of attachments have springs hold the outer plate of a fuel tank, and an inner jig positions an inner plate. The attachments are attached to clamp arms which are opened/closed by cylinders. When the overlap portion between the outer and inner plates is welded, the thermal deformation caused by welding is accommodated by the springs. The attachments are spaced from the fuel tank in the order in which the welding point is approached.
