Gas Tungsten Arc welding MCQ with Answers

26) Which gas is inactive or deficient is active chemical properties in TIG welding?

Answer is:

Argon

Explanation:

Inert gas (usually Argon) is inactive or deficient in active chemical properties. The shielding gas serves to blanket the weld and exclude the active properties in the surrounding air.

27) What is the purpose of inert gas used in TIG welding?

Answer is:

To protect the molten metal from the atmospheric contamination
