Which industry is mentioned as benefiting from GTAW in the class summary?

• A. Construction and maintenance of ships and power plants
• B. Automotive exhaust systems only
• C. Plastic welding
• D. Woodworking

Answer: (A)

Gas tungsten arc welding is valued for delivering very precise, clean welds on metal structures, especially when quality and appearance matter. The class summary identifies the construction and maintenance of ships and power plants as a sector that benefits from GTAW because these applications require strong, corrosion-resistant joints in metal components—often in tight or demanding positions and with alloys like stainless steel. GTAW gives you good control of heat input, minimizes distortion, and provides high-quality welds across thin and thick sections, which is essential for the safety and longevity of ships and power plants. The other options don’t align with what the summary emphasizes: automotive exhaust systems, plastic welding, and woodworking involve different materials or scopes that aren’t singled out for GTAW in the summary.
