A neutral flame is obtained by supplying an Equal volumes of oxygen and acetylene.
A neutral flame is obtained by supplying an Equal volumes of oxygen and acetylene.
When more volume of acetylene and less volume of oxygen is supplied, then a Carburising flame is obtained.
carburizing flame is one with little oxygen, which produces a sooty, lower-temperature flame. It is often used to anneal metal, making it more malleable and flexible during the welding process.
Neutral flame is used to weld
* steel
* cat iron
* copper
A slightly oxidizing flame is used in torch brazing of steel and cast iron. A stronger oxidizing flame is used in the welding of brass or bronze.
A carburizing flame is advantageous for welding high carbon steel and hard facing such nonferrous alloys as nickel and Monel.
Carburising flame is used to weld Hard surfacing materials such as stellite
