<P>PROBLEM TO BE SOLVED: To provide a welding technique capable of performing welding effectively even in a minute area. <P>SOLUTION: When a first resin 50 and a second resin 60 are welded, a metal chip 30 is pressed against the surface of the first resin 50 by a support 35. A laser light is emitted from a laser light source 10 of a welding apparatus and applied pulsewise to this metal chip 30. The area irradiated with the laser light is turned into plasma and the shock wave reaches the joining face of the resins (50, 60). By repeating this shock wave friction, heat is generated in the joining face of the resins (50, 60) and both the resins are welded. <P>COPYRIGHT: (C)2007,JPO&INPIT |
