Air acetylene welding is one type of gas welding process, where unit body is produced by the heating work piece. The heat is produced from mixture of acetylene and air. Weld joint is made without the application of pressure and with or without use of filler metal.
Air acetylene welding
Air acetylene welding working principle:
Bunsen burner working principle is followed in air acetylene welding torch. A certain amount of pressure acetylene gas is flowing through Bunsen jet torch and same time a suitable amount of air included. Such this a weld-able flame is produced.
First acetylene gas is flown through a proper hose and it is regulated by a valve system. Acetylene gas is mixed with automatic included air for combustion. During combustion required amount of oxygen is obtained from air. There a special designed torch is used.
Application of air acetylene welding:
The flame temperature is lower than the other kind of fuel acetylene and oxygen welding. The following application-
Where soft solder is required for copper plumbing.
Lead welding purposes (of course small cross section).
Small thickness copper sheet welding.
Refrigerant copper tube joining.
Gas welding
Arc welding
Resistance welding
Solid state welding
Radiant energy welding
Thermo-chemical welding
