A welding apparatus comprises a pair of suspension type electrode press devices for clamping an upper electrode and a lower electrode in perpendicular relation to workpieces for synchronizing them, whereby a clamping force is treated as the inner force of the pushing mechanism and the apparatus can be miniaturized. The surfaces of the workpieces can be uniformly clamped by the upper and lower electrodes whereby the consumptions of the upper and lower electrodes are substantially the same and the calibration of the positions of the upper and lower electrodes for consumption is not required. |
