Answer Details
Oxyacetylene flame is used for iron-welding because it evolves a lot of heat when burnt. The oxyacetylene flame is produced by mixing oxygen and acetylene gases. The flame produced has a temperature of around 3000°C, which makes it very hot and suitable for welding iron. The high temperature of the flame allows the metal to melt quickly, making it possible to fuse two pieces of metal together. The flame also produces a reducing atmosphere that protects the weld from oxidation and other impurities, ensuring a strong and clean weld.
