Abstract
An apparatus for weld build-up on a surface of revolution within a bore has a head assembly, an elongated line shaft, a step assembly and a traveling assembly. The head assembly has a housing that may be fixedly mounted in a region spaced from the surface of revolution, the housing defining a chamber with an axis in alignment with an axis of revolution. It also has a spindle mounted for rotation within the chamber, coaxial with the axis of revolution. The line shaft is coupled to the spindle and extends for coaxial rotation within the bore in a region of the surface of revolution. The step assembly is fixedly mounted upon the line shaft. The traveling assembly is mounted also upon the line shaft and disposed for rotation within the bore. The traveling assembly consists of a wire reel, a wire feeder, and an electrical welding torch assembly that terminates in a torch nozzle. The step and traveling assemblies are fixed upon the line shaft for rotation within the bore, and the axial spacing between step assembly and the traveling assembly along line shaft are adjustable.
