GTAW PROCESS TIG welding produces an precise weld and is a commonly used as high quality welding process. TIG welding has become a popular choice of welding processes when high quality, precision welding is required. DC polarity is used in most welding applications. It produces a smoother welding output compared to AC. It creates a more stable arc, easier welding and less spatter. You can also either use DC negative for faster deposition rates when welding thin sheet metal or use DC positive for more penetration into the steel. Advantages: Produces very high-quality, superior welds, Leaves no slag or splatter. Particularly high visual quality of weld seams Uses a number of shielding gases including Helium (He) and Argon (Ar) Is easily applied to thin materials and Welding yields low distortion, Welds can be made with or without filler metal All welding positions are possible
