TIG (GTAW) filler rods are used in the gas tungsten arc welding process, where the welder manually feeds the rod into the weld pool while maintaining the arc with the torch. TIG welding produces the highest quality, lowest spatter welds and is the process of choice for precision work on stainless, aluminum, titanium, and exotic alloys.
- Lincoln category: Filler Metals - Special Alloys;Filler Metals - Chrome-Moly Alloys
- Compatible families: SuperArc
- Electrode type: TIG Rod
TIG (GTAW) filler rods give welders precise control over the weld pool because the filler is fed manually rather than carried in the arc. Choosing the correct alloy and diameter keeps weld chemistry, penetration, and bead appearance consistent across procedures.
Low Alloy Steel • AWS A5.28 ER80S-B2
- B2 alloyed steel: 1.25% chromium, 0.5% molybdenum alloyed steel consumable designed for prolonged elevated temperature service up to 550°C (1022°F)
- Excellent corrosion resistance in refineries to sulfur bearing crude oil at 250°C-450°C (482°F-842°F)
- Capable of exceeding AWS minimum requirement of 550 MPa (80 ksi) tensile strength after 8 hours of stress relieving at 620°C (1150°F)
- Weld metal chemistry is low in impurity elements allowing it to respect the X Factor (<15ppm) and J-factor (<120ppm)
