Abstract: Various processes for the addition or build-up of material such as base metals or alloys onto tool joints and/or threads of drill pipe typically used in, but not limited to, the gas and oil industry are disclosed. In one example, a spiral delivery of material is described, as well as, a machine that delivers the material onto the tool joints and/or threads of drill pipe. Variables can be temperature used during pre-heat, application, inter-pass and/or post process, electrical current used (AC/DC), volts, amps, wire type and size, cooling process, width and depth of bead applied, rotation, and travel speed.
