    TIG Welding

    TIG (Tungsten Inert Gas) welding, which is widely used in the aerospace industry, is a method of melting and bonding both base materials with arc heat generated between tungsten electrodes and base materials, which are non-consumable electrodes.
    ▶ PROCESS : MATERIAL INSPECTION → Pretreatment → Pre-Fit → Welding → INSPECTION


    Application
    field

    welding of nonferrous metals such as aluminum, magnesium, and stainless steel

    Production of Aerospace Parts

    All industries requiring high-quality welding

    Coating
    materials
    Use welding rods suitable for base material (AWS D17.1)

    Aluminum welding rod: ER4043, 5356, etc

    Steel welding rod: ER347 etc

    Process
    condition

    Electrode: Non-consumable tungsten electrode (melting point 3,400°C)

    Shielding gases: inert gases such as argon, helium, etc

    Welding method: Current supply using foot pedal

    Process
    characteristics

    Heat input adjustment is possible during welding, making it easy to weld thin sheets

    Less impurities mixed and better arc stability

    Welds are less deformed and no slag is generated

    High-quality and high-purity welds compared to other bonding processes
