Surfacing the surface or edges of the metal parts, Tungsten Welding Electrodes wear-resistant, corrosion or the metal layer of the special properties of the repair failed shape metal parts and products, improve service life, reduce production costs, or use it static build bimetal parts.
Surfacing is A process for the special properties of the metal layer of the wear and corrosion on the metal material or the surface of the parts welded. Appearance unqualified surfacing can repair metal parts and products, or manufacture of bi-metallic parts. Using surfacing can extend component life, reduce costs, improve product design, especially for the rational use of materials (especially precious metals) has important significance.
Surfacing technology has been widely used in the aerospace, weapons, energy, metallurgy, power plants, mining, petroleum, chemical equipment, construction, agricultural, textile, and tool and die manufacturing and repair field.
Classification of surfacing materials
All surfacing materials can be grouped into several types of iron-based, nickel-based and cobalt-based tungsten carbide base and copper. Welding Accessory range of iron-based surfacing material properties, good toughness and wear resistance matching, to meet the many different requirements, and the price is low, so the most widely used. Nickel-based and cobalt-based surfacing material prices higher, but the high temperature performance, corrosion resistance, mainly used for the wear requirements of high temperature, high temperature corrosion occasions. The corrosion resistance of copper-based surfacing materials and reduce metal wear. The higher tungsten carbide-based surfacing material prices, but under conditions of severe abrasive wear resistance, surfacing still occupies an important position.
