contactWhat is flame cutting? Flame cutting is oxygen cutting in which the appropriate part of the material to be cut is raised to ignition temperature by an oxy-fuel gas flame (definition from BS 499:Part 1:1991 Section 7 No.72 002). Also known as oxy-fuel cutting, the process is used for separating and shaping steel components.

contact202324 · A neutral flame is mostly used for gas welding processes. 3. Oxidising flame. Oxidizing flame is the main flame used in the gas cutting process. It is the flame used to cut the metals because it oxidizes the
contactThe flame cut can be done with a flame cutting gauge, thus a 90° cut to the rail is possible. If rails with 880 N/mm² minimum tensile strength are installed then the rails should be warmed before the start of flame cutting. The rail should be warmed over a length of 1 m around the place to be cut (to about 50°C).
