IN A FIRST STEP (SI), A FIRST CURRENT VALUE (CL) IS APPLIED BETWEEN A WELDING ELECTRODE (10) AND A GROUND ELECTRODE (20) WHILE A FIRST PRESSURE (F1) IS APPLIED TO A JOINING PORTION (P). IN A SECOND STEP (S2), A SECOND CURRENT VALUE (C2) LOWER THAN THE FIRST CURRENT VALUE (C1) IS APPLIED BETWEEN THE ELECTRODES (10, 20) WHILE DECREASING THE PRESSURE BEING APPLIED TO A SECOND PRESSURE (F2) LOWER THAN THE FIRST PRESSURE (F1). IN A THIRD STEP (S3), A THIRD CURRENT VALUE (C3) HIGHER THAN THE FIRST CURRENT VALUE (CL) IS APPLIED BETWEEN THE ELECTRODES (10, 20) WHILE THE SECOND PRESSURE (F2) IS APPLIED TO THE JOINING PORTION (P). IN A FOURTH STEP (S4), A FOURTH CURRENT VALUE (C4) HIGHER THAN THE THIRD CURRENT VALUE (C3) IS APPLIED BETWEEN THE ELECTRODES (10, 20) WHILE THE SECOND PRESSURE (F2) IS APPLIED TO THE JOINING PORTION (P).
