Argon-Carbon dioxide​

Answer 1

Explanation:

Which of the following gas mixtures is not used in Gas tungsten arc welding (T!G)?

Argon-Carbon dioxide

Answer 2

The correct answer is OPTION 2: Argon-Nitrogen.

• Tungsten inert gas welding is another name for gas tungsten arc welding.
• In this approach, metal coalescence is achieved by heating the base metal with an arc between it and a non-consumable tungsten electrode.
• The tungsten electrode's primary duty is to keep the arc alive.
• A gas or gas mixture, commonly helium, argon, or a combination of the two, provides shielding.
• Depending on the joint arrangement, pressure and filler metal may or may not be used.
• Any metal or alloy can be used to make high-quality welds.
