<P>PROBLEM TO BE SOLVED: To provide a welding apparatus capable of enhancing stability and strength of a joined part. <P>SOLUTION: The welding apparatus 1 mainly includes a first electrode 20 to which the current is supplied, a second electrode 30 which is provided separately from the first electrode 20 and where the current flows in via a member to be welded, and a pressing member 40 which is provided between the first electrode 20 and the second electrode 30 to apply the pressure to the member to be welded. Since the pressure can be applied between the first electrode 20 and the second electrode 30 by the pressing member 40, the welding apparatus 1 is capable of suppressing variation of contact resistances, and enhancing the stability and the strength of a joined part 84. <P>COPYRIGHT: (C)2013,JPO&INPIT |
