Oxy Acetylene Welding

Oxy acetylene welding is a type of welding that uses oxygen in order to generate the heat needed for the welding process. It is also used for cutting pieces of metals.

It was a pair of Frenchmen who pioneered the use of the process at the beginning of the twentieth century. They used pure oxygen to generate enough heat to melt metals. This type of welding process is not as frequently used now as it was in the past but it is still highly favoured when working on some repair work. It is also used in creating art pieces.

Despite the fact that there are more modern welding techniques in use right now oxy acetylene welding still holds some advantages over other types of welding and here are some of those advantages:

-Oxy acetylene welding is easier to learn and master when compared with other types of welding process.

-The equipment needed for oxy acetylene welding is cheaper when compared with the equipment needed for other forms of welding.

-Aside from being cheaper the equipment for oxy acetylene welding is also easier to move around and transport.

– The tools in oxy acetylene welding can also be useful in cutting large chunks and pieces of metal giving them a dual purpose.

While OA welding has its advantages it has its drawbacks. The weld done with OA welding looks rough and it requires more work to make it look finished and the metal parts that have undergone OA might have weakened and their properties altered. Steel and brass are the two metal types that are most suited for working on OA Welding.

Here are some tips that you can keep in mind when doing OA welding:

– Safety is always the most important thing to remember when doing any form of welding work. With oxy acetylene welding you need to be extra careful because you are dealing with flames and a tank of highly combustible material.

– Make sure to clean the surface of the parts that are to be welded. Use a steel brush if necessary. You have to be sure that the surface to be welded is free from any form of contaminant that might spoil your work.

– Pick the appropriate nozzle to use for the project. Large nozzles can create huge flames that are suitable for working on large pieces of metal. Finer work requires smaller nozzles.

– Make sure that the nozzle is clean and free from any dirt. Carbon deposits tend to build up inside the nozzle after repeated use and that might interfere with your work.

– Make sure that the acetylene tank shows at least 50 psi in the gauge. You can use the one for oxygen until the tank is empty.

– Be very careful when starting the flame. Make sure that there is nothing combustible nearby when you start the flame.

– Never start the flame while the valves for both oxygen and acetylene are open. Only use the acetylene and then slowly open the oxygen. The flame should turn bluish once the oxygen is increased.
