Question

why oxyacetylene flame used in welding process and why only at high temperature​

Answer 1

Answer:

hope it helps

Explanation:

Oxyacetylene burns to produce a lage amount of heat which is sufficient for melting metals. Therefore it is used for welding purposes. On heating Oxy acetylene produces a large amount of heat and a huge temperature about 5000-6000 degree Celsius which is enough to melt metals like iron etc.

Answer 2

The oxy-acetylene welding process combines oxygen and acetylene gas to provide a high temperature flame for welding. This temperature provides enough heat to melt most metal. This flame can be used to melt metal and flame is directed by welding torch.

The temperature of the flame can reach as high as 6,300 (3,480)." Thomas Wilson created the oxyacetylene torch in 1903. He combined both pure oxygen (99.5%) and acetylene in proper proportions to yield a flame of about 3,480 degrees Celsius. Oxyacetylene the only gas mixture that will burn hot enough to cut steel.
