Which types of metals can be welded using GTAW?

GTAW, or Gas Tungsten Arc Welding, is a versatile welding process known for its ability to weld a wide range of metals. The correct choice reflects this versatility, stating that both ferrous and non-ferrous metals, as well as dissimilar metals, can be welded using this method.

Ferrous metals, which contain iron, include steel and cast iron, making them common materials in construction and manufacturing. Non-ferrous metals, such as aluminum, copper, and titanium, have specific properties that often require specialized techniques, which GTAW can accommodate due to its clean, precise control over heat input. Dissimilar metals can also be joined effectively with GTAW, allowing for innovative material applications in industries that require strong bonds between different metal types.

The method's ability to provide a clean weld pool, control heat input, and work in various environments contributes to its effectiveness across this range of materials. Understanding this capability is essential for selecting the appropriate welding technique based on the materials involved in a project.
