Hey Dear,

◆ Answer -

Acetylene

● Oxy-acetylene welding -

• This welding uses flame obtained by burning of acetylene with oxygen.
• Oxygen & acetylene are stored in separate cylinders and transported to the torch.
• Flame is concentrated at the joint edges until metal melts.

Acetylene is preferred as fuel gas because -

1. triple bond of acetylene stores lot of energy
2. it has high flame temperature & high rate of flame propagation

Hope this helped you.
