This disclosure provides an apparatus, system, and method for thermal spraying a metal cladding on a substrate. The apparatus may include a housing having a first electrode and a second electrode disposed in the housing. The second electrode can be spaced apart from the first electrode. The apparatus includes a first contact tip removably attached to the first electrode and a second contact tip removably attached to the second electrode. The position of the first contact tip and second contact tip is configured to be selectively adjusted on the first electrode and the second electrode to provide a plurality of contact surfaces for a feedstock wire. The apparatus includes a nozzle between the first contact tip and the second contact tip. The first contact tip and the second contact tip are configured to contact and deflect a wire towards the nozzle.

The present invention relates to the field of surface alloy pipe manufacturing, and provides a process and spraying equipment for arc spraying carbon steel pipes. The process includes the following steps: S1: installing a raw metal wire on a wire feeder, adjusting the wire feeding voltage according to the required thickness of spraying, and adjusting the spraying current according to the material of the raw metal wire; S2: spraying an inner and outer walls of the pipe through an inner wall spray gun and an outer wall spray gun; S3: after the pipe being sprayed, cooling it naturally to room temperature; S4: putting the cooled pipe into a heating furnace, adjusting the heating temperature according to the required surface alloy thickness, and cooling it in the furnace or natural cooling outside the furnace after the insulation is completed; meanwhile, a surface alloy layer is formed on the inner and/or outer wall of the carbon steel pipe; S5: after the pipe being cooled to room temperature, using a medium frequency heat treatment equipment to heat-treat the pipe through the heat treatment process. The present invention solves the problems that the existing arc spray equipment cannot spray the inner wall of the pipe, and the spray coating has poor bonding force with the pipe body and is easy to fall off. It greatly improves the wear resistance, high temperature resistance and anti-corrosion performance of the inner and outer wall surfaces of the pipe, and increases the pipe life.
