WebOxy-fuel cutting begins by using a torch to heat a metal to its kindling temperature. This is the lowest temperature at which the metal in question will spontaneously ignite. At this point, a stream of oxygen is trained onto the metal, in turn burning it into a metal oxide.
WebFeb 8, 2024 · Oxyfuel cutting heats metal to ignition temperature with an oxygen and fuel gas flame. A chemical (exothermic) reaction between the oxygen and carbon steel creates iron oxide, referred to as slag, which is blown out of the gap by the high pressure of the gases used.
