Because oxygen react with acetylene and form oxyacetylene gas which helps in welding process.

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

Oxygen react with acetylne and forms diff types of flame which is at very high temp.

Argon is also used guys... not only oxygen and acetylene... correct answer is C

After reaction between 02 and C2H2 the Oxyacetyline flame is produced.Which can produced the temperature approx 2500-3000 degree.

In welding process we will use three methods.

1. Thermal welding.

2. Electric arc welding.

3. Gas welding.

In gas welding the most widely used method is OXY-ACETYLENE welding.

Oxy-hydrogen is also suitable for welding because it is 2800 celsius and oxy-acetylene flame is 3300 celsius.

I'm agree with vishal now-a-days argon gas is used in industries

Abp said:   1 decade ago
Argon is used to provide a inert atmosphere surrounding the welding.
