O2 + C2H2---> Oxyacetylene gas and very hot temperature. this temperature helps to welding.

Salman said:   1 decade ago
Because oxygen react with acetylene and form oxyacetylene gas which helps in welding process.

Its oxyacetylene gas which melts metals like iron steel etc. So right answer is option D.

Deepa gupta said:   1 decade ago
Mixture of oxygen and acetylene forms oxyacetylene gas which helps in welding process.

R D said:   1 decade ago
It is also called as oxyacetylene gas and has ability to create very high temperature.

Vinay said:   1 decade ago
oxygen react with acetylene form oxy acetylene which produces a very high temperature

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.
