<P>PROBLEM TO BE SOLVED: To weld with high welding efficiency by reducing reflection loss of radiated light in welding technology for welding a member by the radiated light. <P>SOLUTION: In the welding technology, a light transmissive second member 2 is closely attached to a first member 1, and a laser light L, which is deflected and controlled, is radiated from a second member 2 side to weld both members at a welding surface R. A reflectivity reducing means formed of an incident angle adjusting step 141 formed on a pressing plate 14 arranged on a light irradiation surface side of the second member 2 reduces incident angles θ1, θ2 of light on light irradiation surfaces of the first member 1 and the second member 2, to reduce the reflection loss of the laser light at the light irradiation surfaces and improve welding efficiency. <P>COPYRIGHT: (C)2013,JPO&INPIT |
