RESISTANCE WELDING METHOD AND RESISTANCE WELDING STRUCTURE

Japanese Patent JP2016022508

A

PROBLEM TO BE SOLVED: To provide a resistance welding method and a resistance welding structure capable of easily performing firm resistance welding even for a plate material having a high electrical conductivity when members to be welded arranged in a row and two sheets of plate materials which are brought into contact with the members to be welded are subjected to resistance welding while leaving a gap between the plate materials in a width direction.SOLUTION: A plurality of plate materials 2, 3 have a long and narrow shape continuously elongated along the row direction Y and are brought into contact with respective members 1 to be welded, two sheets of plate materials are arranged in parallel to the width direction X leaving a predetermined gap S, and projections 5 which are projected respectively toward welding portions 1a are formed opposite to the welding portions 1a of the members to be welded, on the respective plate materials. Each of a pair of welding electrodes 10, 11 is brought into contact with an outer surface of the side opposite to the member to be welded on the plate material, the pair of welding electrodes are separated and arranged in the width direction X, electricity is conducted between the welding electrodes and two sheets of plate materials are subjected to projection resistance welding onto the welding portions of the respective members to be welded.SELECTED DRAWING: Figure 1
