Thermal Cutting Processes

Linde is expert in all matters pertaining to “thermal cutting” (i.e., the parting or shaping of materials by applying heat, with or without a stream of cutting oxygen).

Oxy-fuel and plasma cutting are the dominant thermal cutting processes, and they compete in many areas with laser cutting.


Thermal Cutting - Oxy-fuel Cutting

In industrial applications, oxy-fuel cutting is the predominant process for cutting heavy-gauge mild and low-alloy steels. It belongs to the family of flame processes that also includes flame gouging and cleaning, flame heating, flame straightening, soldering and brazing, among others.

Acetylene is often the fuel gas of choice for oxy-fuel cutting processes. (PDF 256 KB)

Thermal Cutting - Plasma Cutting

Plasma (arc) cutting was developed in the 1950s, to cut metals that could not be flame-cut (e.g., stainless steels, aluminum and copper). It is now used to cut mild and low-alloy steel, and high-precision plasma-cutting units are available.

Thermal Cutting - Laser Cutting

A laser resonator emits a low-divergence beam of light with a well-defined wavelength that, when focused to a small spot, is capable of cutting metal. Most laser-cutting machines in metal fabricating shops are powered by a CO2 resonator and range in power from 1.5 kW to 6 kW.
