Petroleum industry: It is used for the inner - wall surfacing of equipment such as valves, pipe fittings, and flanges to enhance corrosion and wear resistance, ensuring safe production.Thermal power industry: Mainly used for the on - line repair of valve sealing surfaces to reduce energy l...

Improve equipment corrosion resistance: During oil and gas exploration and transportation, equipment faces complex and corrosive media, such as oil and gas containing hydrogen sulfide and carbon dioxide. Hot wire TIG surfacing can deposit corrosion - resistant alloy materials on the surface of...

Hot wire TIG surfacing (Tungsten Inert Gas Welding with Hot Wire) is an advanced welding and surfacing process. Based on traditional TIG welding, it adds an additional heating device for the filler wire. During the welding process, the filler wire is preheated, so that the wire reaches a relatively...
