But in heavy fabrication units co2 and argon mixture is also use for MS welding. And for SS welding pure ARGON gas is use.

ALSO, HYDROGEN gas is used in atomic hydrogen welding for shielding the weld zone. Hence protecting the welded part from oxidation or contamination.

H2, C2H2+O2, ARGON (MIG WELDING).

Best resembling option will be option C.

What is thermal welding?

Abhishek said:   1 decade ago
Argon gas also used, now these days argon gas used in welding. So correct answer C.

Abhay said:   1 decade ago
Argon being inert gas used to cover welded portions to protect it from oxidation.

Depending on the type of welding, Oxygen can be used in combination with a gaseous fuel (acetylene or hydrogen). Argon is used as the shielding gas, which helps to protect the weld from any external interference.

Correct option is (C). Because argon is used in tungsten inert gas welding as a shielding gas to protect weld pool.

Guys correct answer is c. Because argon is also used in tungsten arc welding.
