  Job knowledge for welders 3: The oxyacetylene welding [gas welding] process
Oxyacetylene welding, commonly referred to as gas welding, is a process which relies on combustion of oxygen and acetylene.
The action of the oxyacetylene flame on the surface of the material to be welded can be adjusted to produce a soft, harsh or violent reaction by varying the gas flows.
The principal techniques employed in oxyacetylene welding are leftward, rightward and all-positional rightward.

  Oxyacetylene - Wikipedia, the free encyclopedia
Oxyacetylene is a gas welding process using acetylene and oxygen.
An oxyacetylene torch can also be used for cutting metal by heating the metal until it glows and then pressing a lever on the torch which allows an excess of oxygen to be added to the gas mixture.
Oxyacetylene welding is not difficult, but there are a good number of subtle points that should be learned such as: never fully empty an acetylene cylinder or use more than 1/7 the capacity of the cylinder per hour.

 Welding_gas, equipment for a self sufficient welding outfit.
If you are too young to have seen Welding_gas, oxyacetylene welding in action in the garage near home, in the farm or in some old flsmith shop, you may think we are talking of an obsolete process, an old time curious scrap.
Our presentation is limited to Welding_gas oxyacetylene welding equipment because it is the most practical and important of all gas welding processes that were researched in the past, but now have only a historic interest.
The regular oxyacetylene Welding_gas Torch can be used also for Hobby and Home Welding and for Brazing, justifying its being considered a very versatile tool.
