Oxyacetylene Welding (OAW)

The Oxyacetylene welding process uses a combination of oxygen and acetylene gas to provide a high temperature flame.

OAW is a manual process in which the welder must personally control the the torch movement and filler rod application. Cylinders contain oxygen and acetylene gas at extremely high pressure.   

Oxy-Acetylene (OA) welding is one of the many types of welding supported by the DP Metals Shop. It is extremely versatile and affordable. Oxy-acetylene welding is simple in concept - two pieces of metal are brought together, and the touching edges are melted by the flame with or without the addition of filler rod.

Advantages of Oxy-Acetylene Welding :

  • It's easy to learn.
  • The equipment is cheaper than most other types of welding rigs (MIG/TIG welding)
  • The equipment is more portable than most other types of welding rigs (MIG/TIG welding)
  • Oxy/Acetylene equipment can also be used to "flame-cut" large pieces of material.

Disadvantages of Oxy-Acetylene Welding :

  • Oxy/Acetylene weld lines are much rougher in appearance than other kinds of welds, and require more finishing if neatness is required.

  • Oxy/Acetylene welds have large heat affected zones (areas around the weld line that have had their mechanical properties adversely affected by the welding process).

Materials Suitable for Oxy/Acetylene Welding:

  • Mild Steel
  • Brazing can be done on many other materials i.e. aluminum, stainless steel, copper, and brass
