Gas cutting It is popular because there is no need for electricity, no need for a special room, the gas cutter is small enough and mobile in movement. gas cutting the cutting surface is heated with propane or acetylene to a temperature of 1000 - 12000C. After this, a stream of oxygen is supplied, which, upon contact with the heated surface, ignites and begins cutting the metal. During the cutting process, it is important to maintain a continuous supply of oxygen, otherwise the flame will go out.
Gas cutting not applicable to metals with melting points below 6000C, since cutting is practically impossible. The cutting width can range from 2 mm to 10 mm and can be done manually or by automatic machines. Gas cutting It can be oxygen, oxygen-flux, or lance welding and is used for different thicknesses of metal.
Gas welding and cutting Metals have synonymous similarities in that the part must be heated to a specific temperature, requiring propane, acetylene, or a substitute, oxygen cylinders, hoses, cylinder feeds, a torch, and a welding table. However, welding requires filler wire, a set of torch tips for heating metal of different thicknesses, fluxes, and welding powders.
At gas welding and cutting Industrial oxygen is extracted from air processed in special air separation units. There, it is purified from carbon dioxide and dried to remove moisture. Most filler wires are used with a composition similar to the metal being welded; it is essential to know the wire grade. During welding, it should melt evenly and smoothly, and upon solidification, the resulting metal should be homogeneous.
