What does TIG stand for?

  1. Thermal Inert Gas

  2. Thermal Ion Gas

  3. Tungsten Inner Gas

  4. Tungsten Inert Gas

The correct answer is: Thermal Inert Gas

TIG stands for Thermal Inert Gas. This method of welding uses an inert gas, most commonly Argon, to protect the weld pool from atmospheric contamination. This creates a cleaner, higher quality weld. The other options are incorrect because thermal ion gas is not a commonly used term in welding and Tungsten Inner Gas is not a method of welding. While Tungsten Inert Gas is a similar term, it is often used interchangeably with Gas Tungsten Arc Welding (GTAW). Therefore, TIG is the most accurate and commonly used term for this welding process.
