More Information
Summary:A laser welding jig for preventing resin extrusion and deformation when performing laser welding to join resin parts. The jig holds a first resin part (12) transmissible to laser light and a second resin part (13) that absorbs laser light. The first resin part is joined with the second resin part in a superimposed state. The jig is used to thermally weld the first resin part and the second resin part at a joint (12a, 13a) of the first and second resin parts. The jig includes a heat releasing means (117; 32; 44; 45; 23) arranged outward from the first resin part and the second resin part for absorbing and releasing heat generated by laser light at an outer side of the joint.
