Oxyfuel cutting

The oxyfuel cutting technique is an auxiliary welding process, by which metals can be sectioned by means of local and continuous combustion in the presence of any combustible gas (acetylene, hydrogen, propane, coal, tetrene or crylene) in combination with pure oxygen ( in percentages greater than 99%).

This cutting technique was developed at the beginning of the 19th century and has been used to this day in countless industrial applications for the preparation of the edges to be welded.

Flame cutting phases

The flame cutting consists of two stages: Preheating and Cutting

Preheating

In the first preheating phase the flame reaches temperatures between 2425 ºC and 3320 ºC, depending on the type of combustible gas and the richness of oxygen in the mixture.

Cut

In the second phase, an oxygen current cuts the metal and eliminates the iron oxides produced
