ABSTRACT:
For welding tongues (12) onto sheet-metal parts (10), particularly tear-open can parts, a welding machine having at least one pair of welding electrodes (62, 63) is provided. The sheet-metal parts (10) can be moved through the machine steps between the welding electrodes (62, 63), one behind the other, by a sheet-metal conveyor (15) and be located in a defined position by a positioning device (17). The tongues (12) can each be placed against a sheet-metal part (10) between the welding electrodes (62, 63) in synchronism with the working cycle of the sheet-metal conveyor (15) by a tongue conveyor (18).
