<P>PROBLEM TO BE SOLVED: To temporarily hold and weld metal parts without causing any increase in the number of equipment items. <P>SOLUTION: In a bonding step, an adhesive 16 is applied to a part of a surface where a parent part 12 and a child part 14 make contact with each other, and then the parent part 12 and the child part 14 are accurately positioned and bonded to each other temporarily. In a conduction path forming step, a nugget 20 is formed in an area other than the area to which the adhesive 16 has been applied on a contact surface of the parent part 12 and the child part 14. In a welding step, an electrode 24 of a spot welding machine abuts on the parent part 12 and the child part 14 to apply an electric current to the parent part 12 and the child part 14, the adhesive 16 is heated and melted by the Joule heat generated at the parent part 12 and the child part 14, the adhesive 16 is removed from the area to which the adhesive 16 has been applied and then the parent part 12 and the child part 14 are brought into contact with each other, and the area to which the adhesive 16 is applied in the bonding step is subjected to spot welding so that the parent part 12 and the child part 14 are bonded to each other. <P>COPYRIGHT: (C)2012,JPO&INPIT |
