Gas Tungsten Arc Welding (GTAW), also known as TIG (Tungsten Inert Gas) welding, is particularly versatile and is commonly used to weld a range of metals due to its ability to produce high-quality, precise welds. The method is particularly effective for welding stainless steel, aluminum, and other non-ferrous metals, which can often present challenges with distortion and oxidation.

Stainless steels possess properties that make them ideal candidates for GTAW, such as corrosion resistance and aesthetic appeal. Similarly, aluminum, known for its lightweight and strength, benefits from the controlled heat input and precision of the GTAW process, allowing for clean connections without excessive spattering.

While GTAW can technically weld different types of metals, including ferrous metals, the focus is primarily on non-ferrous materials in this context. The high degree of control offered by GTAW is particularly advantageous for materials like aluminum and stainless steel, thus making option B the most suitable choice.

The other options refer to materials that, while they may be welded using other methods, don't represent the primary benefits or capabilities associated with GTAW. For instance, carbon steel and cast iron can be welded effectively, but other welding processes, such as MIG or stick welding, are generally
