Which statement is an advantage of GTAW?

• A. It yields high travel speeds and high deposition rates
• B. Little or no post-weld cleaning is necessary
• C. It always leaves slag behind
• D. It cannot weld aluminum

Answer: (B)

Gas Tungsten Arc Welding shines because it produces clean welds with little or no post-weld cleaning. This comes from using a non-consumable tungsten electrode and an inert shielding gas without any flux, so no slag forms during the weld. The result is a neat, precise joint that often requires only minimal finishing, which is especially valuable on thin materials or critical parts where appearance and tight tolerances matter. If you think about other aspects, GTAW isn’t chosen for high deposition rates or fast travel speeds; its strength is precision and quality. And yes, GTAW can weld aluminum (with the right setup, typically AC to manage the oxide layer).
