Which of the following is an attribute of welds produced by GTAW?

Welds produced by Gas Tungsten Arc Welding (GTAW) are known for their high quality and strong performance in various applications, particularly due to their excellent corrosion resistance. This attribute is a significant advantage when welding materials that are prone to degradation in corrosive environments, such as stainless steel and aluminum. The GTAW process, which uses a non-consumable tungsten electrode and a shielding gas, produces a clean and concentrated arc that minimizes contamination and oxidation during welding. As a result, the welds created are often smooth, with minimal impurities, contributing to enhanced durability and resistance to corrosion over time. This is essential for structural applications where long-lasting performance is critical.
