<P>PROBLEM TO BE SOLVED: To provide a laser welding apparatus capable of enhancing the welding strength of a transmitting material and an absorbing material. <P>SOLUTION: In the laser welding apparatus A for welding the laser transmitting material W1 and the laser absorbing material W2 by irradiating the joined surface of both materials with a laser beam from the side of the transmitting material W1 in a state that both materials are superposed one upon another, a pressurization means 2 for applying pressure toward the joined surface from the surface of the transmitting material W1 in the state that both materials W1 and W2 are superposed one upon another is provided. The pressurization means 2 can individually adjust pressures corresponding to a plurality of the pressure places set to the surface of the transmitting material W1. <P>COPYRIGHT: (C)2012,JPO&INPIT |
