Abstract
In a welding apparatus for the longitudinal seam welding of can bodies (31′) by way of electrode rollers (8, 17), three drive stages (4, 10, 20), by means of which the wire electrode (25) is driven in addition to the drive by the electrode rollers (8, 17), are provided in the wire course. Preferably, elastic stretching is brought about in this case by the three drive stages (4, 10, 20).
