Identify use of argon from following.
- A In supersonic wind tunnels
- B For magnetic resonance imaging
- C For producing inert atmosphere in welding
- D For production of lasers
Answer & Solution
Correct Answer
(C) For producing inert atmosphere in welding
Step-by-step Solution
Detailed explanation
Argon is used in the welding of specialty alloys as well as in the welding of automobile frames, mufflers and other automotive parts. It is called a shield gas because it does not react with whatever gases and metals are hovering in the vicinity of the metals being welded; it merely takes up space and prevents other, unwanted reactions from occurring nearby owing to reactive gases such as nitrogen and oxygen.
