Welding: When burned in oxygen, acetylene produces a reducing zone, which easily cleans the metal surface. However, propane doesn't have a reducing zone. This property makes it unsuitable for welding. Today, oxy-acetylene welding is employed for high strength steels.

Is oxy-acetylene welding still used?

In recent decades, oxy acetylene welding has become obsolete. Our modern arc welders have more consistency and weld faster. However, oxy acetylene cutting is still a commonly used process that is utilized by millions of welders every day.

What type of welding uses oxy-acetylene?

Process features. Oxyacetylene welding, commonly referred to as gas welding, is a process which relies on combustion of oxygen and acetylene. When mixed together in correct proportions within a hand-held torch or blowpipe, a relatively hot flame is produced with a temperature of about 3,200 deg. C.
