Abstract

The automatic welding machine has a pair of closely spaced magnetic rollers which grip the surface of a workpiece and which are driven to rotate the workpiece. The workpiece may rest on a support on the end of a double articulated arm. The driven rollers are adjustably mounted on a standard. The standard also mounts a carriage including a welding gun. The carriage is movable toward and away from the workpiece under the urgings of a probe which is mounted on the carriage with the gun and which travels over the surface of the workpiece as it rotates.
