ABSTRACT:
A method and machine for weld cladding, particularly for welding material to a cylindrical plate, such as hardfacing or corrosion resistant alloys normally applied as claddings. The machine has a mandrel extending from it for supporting and rotating the plate. The mandrel is supported by beams and driven either by hand or by a motor. Rotating the mandrel rotates the plate supported on the mandrel through the path of a welding apparatus. Flanges can be provided to hold the plate on the mandrel. Bearings can be provided in the beams to facilitate the rotation of the mandrel.
