    Thermal Spray

    Hardfacing Welding

    Hardfacing welding is a method of mixing and burning oxygen and acetylene at a certain rate, melting the solvent at a high temperature of 3000 degrees or higher, and bonding it to the surface to improve corrosion resistance and wear resistance on metal surfaces such as carbon steel, alloy steel, cast iron, and aluminum.
    ▶ PROCESS : MATERIAL INSPECTION → SURFACE ACTIVATION → HARDFACING WELDING → INSPECTION → GRINDING


    Application
    field

    Useful for industrial applications such as cutting tools and wear components

    Improved chemical resistance of equipment in the chemical field

    Improved wear resistance of agitation equipment such as screws

    Coating
    materials

    Tungsten Carbide : Excellent wear/heat/resistant welding rod can be applied to all materials

    Stellite : It has very good characteristics that do not reduce hardness even at high temperatures, so it has very high compression, corrosion resistance, wear resistance, and thermal resistance.

    Process
    condition

    Types of heat sources: oxygen + fuel

    Temperature of heat source: high temperature (3200 ~ 3500℃)

    Injection speed: low speed

    Base material temperature: over 500℃

    Process
    characteristics

    Provides excellent wear resistance and extended life in cutting and abrasion processes

    Formation of high coating thickness compared to other thermal spray processes

    Coating thickness is easily adjusted, so it is easy to repair products with severe wear
