Abstract:
1. A method for forming a joint by joining a portion of a metallic material and a portion of a resin material, comprising: coupling the portion of the metallic material with the portion of the resin material, and fixing by a clamp the portion of the resin material to be joined to the portion of the metallic material to be joined, then heating the portion of the resin material by a laser light source at a temperature that generates fine bubbles in the portion of the resin material to be joined, and wherein the joint obtained has a tensile shear strength of not less than 1 MPa, wherein the metallic material is selected from the group consisting of iron, aluminum, titanium, copper and alloys thereof, wherein the resin material is selected from the group consisting of polyamide resins, polyester resins, and polycarbonate resins, wherein the temperature is at a degree wherein the fine bubbles in the resin material do not transfer from the vicinity of the portion of the resin material to be joined, and wherein the fine bubbles have a sphere equivalent diameter of 0.01 mm to 3 mm.
