Carbon Steel TIG Welding Wire

It is TIG wires for 450 and 500MPa grade carbon steel. Good welding technical performance, all-position welding and beautiful welding performance. It has good crack resistance and higher low temperature impact toughness.

It is mainly used for single pass welding of killed steel, semi-killed steel and rimming steel. No need gas protection at back of joint.

  1. Protection gas flow requirement: The welding current is 100-200A at air flow of 7-12L/min; It is 200-300A at air flow of 12-15L/min.
  2. The extension length of the tungsten electrode should be as short as possible relative to the nozzle, and the arc length should be 1-4mm (2-4mm for welding carbon steel; 1-3mm for low alloy steel and stainless steel welding)
  3. It adopts windproof measurement while wind speed is above 1.0m/s.
  4. Strictly remove grease, rust and moisture impurities while welding.
  5. Welding linear energy directly affects mechanical properties of welding seam metal and crack resistance performance, etc which should be paid more attention to.
  6. The above points are taken into reference.
