PROBLEM TO BE SOLVED: To substantially shorten required process time per work in applying seam welding to a base and a cap with the cap mounted on the base. SOLUTION: A second pallet 41B is overlaid on a first pallet 41A at the lower side placing in a matrix shape a plurality of accommodation spaces prior to tack welding. The base B and the cap C are accommodated over the accommodation spaces of both the pallets 41A, 41B. A welding electrode 11 for tacking is inserted in the electrode insertion spaces E2, E2 of the second pallet 41B to bring the welding electrode 11 for tacking into contact with the cap C. The cap C is tack-welded to the base B. The second pallet 41B is then detached from the first pallet 41A. The entire periphery of the cap C is seam- welded to the base B in a state that the upper edge of the cap C is upwardly positioned rather than the upper surface of the first pallet 41A and with an electrode for seam welding brought into contact with the upper edge of the cap.
