Which material is commonly weldable with GTAW?

Which material is commonly weldable with GTAW?

• A. Mild and low alloy steels
• B. Wood
• C. Plastic
• D. Concrete

Answer: (A)

GTAW, or TIG welding, is a process designed for metals and gives you clean, precise welds with a non-consumable tungsten electrode and inert shielding gas. Mild and low‑alloy steels weld well with GTAW because they respond predictably to the heat input, allowing tight control over fusion and bead appearance, especially on thinner sections. The other options are non-metals (wood) or materials that aren’t typically welded with GTAW (plastics and concrete require different joining methods). So among the choices, mild and low‑alloy steels are the material commonly weldable with GTAW.
