The welding device comprises at least two same-side electrodes, and at least one of the at least two same-side electrodes is an eccentric electrode. Each eccentric electrode comprises a driving cylinder, an electrode seat, and an electrode head, wherein the driving cylinder has a first longitudinal shaft line which extends in the welding motion direction of the eccentric electrode, the electrode seat is connected with the driving cylinder, the electrode seat is suitable be in the welding motion direction of the eccentric electrode under the effects of the driving cylinder, the electrode head can be detachably mounted on the electrode seat, the electrode head has a second longitudinal shaft line, and the second longitudinal shaft line is parallel with the first longitudinal shaft line and is deviated from the first shaft line. Because the longitudinal shaft line (the second longitudinal shaft line) of the electrode is deviated from the longitudinal shaft line (the first longitudinal shaft line) of the driving cylinder, the intervals between welding points are not affected by the diameter of the driving cylinder in multi-point welding processes. Therefore one-step multi-point welding can be realized when intervals between welding points are small.
