What is gas tungsten arc welding (GTAW)? GTAW or gas tungsten arc welding process is a manual welding process that can only be done by an experienced welder. GTAW produces excellent quality and excellent welding quality. This process is often used for pipe welding or pressure vessels with special materials such as high-temperature steel, stainless steel or high strength steel. This GTAW welding process is also often used with the SMAW process, which is in the root (which requires good and clean quality) using the GTAW process and is followed by a faster SMAW process. GTAW (Gas Tungsten Arc Welding) is an electric arc welding process using non-melted electrodes. In this GTAW welding, the electrode or tungsten is only functioning as an arc producer when it comes to contact with the workpiece, while the filler material is the filler rod. This GTAW welding is also often referred to as Argon[…]
