ABSTRACT:
A welding and/or cutting machine 1 is provided for use on a workpiece 2 formed by a pair of metal sheets 3 in face to face contact. The machine comprises a movable carriage 4 mounted on a pair of drive rollers 5 operable to grip the sheets 3 of the workpiece in the nip of the rollers. The axes of rotation 6 of the rollers 5 are disposed so that as the rollers rotate, forces are generated which cause the carriage 4 to be pulled on to the workpiece 2. The carriage 4 is capable of transporting welding means 7 as shown in FIG. 1, for lip-welding the sheets of the workpiece together, or, alternatively, transporting cutter means 10 for subsequent removal of weld material.
