Which industry is listed as requiring GTAW?

• A. Automobile manufacturing
• B. Textile production
• C. Aerospace industry
• D. Software development

Answer: (C)

GTAW is chosen when you need very precise, clean welds with tight control over heat input, especially on thin or difficult alloys. In aerospace, components are often made from aluminum and titanium and must meet strict strength, leakage, and distortion requirements, with joints that pass thorough non-destructive testing. GTAW provides excellent bead quality, low porosity, and the ability to weld delicate or exotic materials with minimal cleanup, which is why it’s listed as required in that industry.

Automobile manufacturing typically uses faster, high-volume processes like MIG and spot welding; textiles and software development don’t involve welding at all.
