<P>PROBLEM TO BE SOLVED: To provide a joining-treatment apparatus wherein a plurality of parts are mutually joined by adhesion or welding. <P>SOLUTION: A joining-treatment apparatus 10 is equipped with a 1st laser head 41 emitting a laser beam B1 for heating an adhesive and with a 2nd laser head 42 emitting a laser beam B2 for welding. When joining the parts, which composes a work W, with a thermosetting adhesive, an adhesion part 30 is irradiated with the laser beam B1 defocused for a short time and the thermosetting adhesive is primarily cured so that the parts are temporarily fixed to each other. When spot-welding the parts mutually, a spot-welding part 31 is irradiated with the laser beam B2 for welding, which is condensed by the 2nd laser head 42. <P>COPYRIGHT: (C)2004,JPO |
