Which metals can be welded using the GTAW process?

The GTAW (Gas Tungsten Arc Welding) process is known for its versatility in welding various types of metals. It is capable of welding all weldable metals, which include both ferrous and non-ferrous materials. Ferrous metals, such as steel and iron, possess magnetic properties and typically require specific techniques to handle their unique characteristics, while non-ferrous metals like aluminum, copper, and titanium have different behaviors during the welding process, often needing specialized filler materials or shielding gases.

GTAW is particularly favored for its ability to produce high-quality welds with a clean, precise arc, making it suitable for a broad range of materials. Its ability to weld thin sections and produce intricate designs also contributes to its extensive application across industries. Therefore, the statement that GTAW can be used on all weldable metals accurately reflects the process's capabilities, emphasizing its adaptability to various welding tasks.
