A SERIES SPOT WELDING METHOD INCLUDES PROVIDING METALLIC PLATES(2,3)OVERLAPPING WITH EACH OTHER, AND EXECUTING A PRESSURE ENERGIZATION TO THE METALLIC PLATES (2, 3) WITH AN ENERGIZATION PATTERN BY USING A PAIR OF ELECTRODES (5, 6) EACH HAVING A SHAPE IN WHICH A DIAMETER IS REDUCED TOWARD A LEADING END THEREOF, SO AS TO WELD THE WORKS. THE ENERGIZATION PATTERN INCLUDES A FIRST ENERGIZATION SECTION(A1)IN WHICH THE ELECTRODES(5,6)ARE SUNK INTO ONE OF THE METALLIC PLATES(2) OVERLAPPING THE OTHER METALLIC PLATE(3)AND THE METALLIC PLATES(2, 3)ARE ENERGIZED WITH A FIRST CURRENT VALUE THAT CANNOT WELD THE METALLIC PLATES(2, 3), AND A SECOND ENERGIZATION SECTION (A2) IN WHICH THE METALLIC PLATES(2,3)ARE ENERGIZED WITH A SECOND CURRENT VALUE THAT IS LARGER THAN THE FIRST CURRENT VALUE AND CAN WELD THE METALLIC PLATES (2,3), AFTER THE FIRST ENERGIZATION SECTION. |
