Abstract

PURPOSE: To perform spot welding of plates to themselves with a small-size device by inserting an insert having protrusions on both sides between an upper plate and lower plate and performing resistance spot welding.
CONSTITUTION: An insert 3 is inserted between an upper plate 1 and lower plate 2 and these are pressed between upper and lower electrodes 6, 7, through which current is supplied. Since heating and melting occurs at the protrusions of the insert 3, the upper plate 1, insert 3 and lower plate 2 fusion-bond, thereby forming fused part 4 and fused part 5 respectively. The upper plate 1 and lower plate 2 are bound by way of the insert 3. The indentation depth generated in the upper plate 1 and lower plate 2 by the upper electrode 6 and lower electrode 7 becomes extremely small because the volume of the insert 3 is added to the nugget part and this increases the volume of the nugget. In case the upper plate 1 and lower plate 2 being the welding works are aluminum alloy or copper alloy requiring large current, this invertion is extremely effective.
