1, rolling wire

Most of the wire belongs to this category, including carbon steel Welding Wire China, low alloy steel wire, alloy steel wire, stainless steel wire and wire and other nonferrous metals.

2, cast wire

Some alloys, such as cobalt-chromium-tungsten alloy, not forging, rolling and drawing, and is made by casting method. It is mainly used for manual welding surface to meet, such as antioxidant, anti-wear and high temperature corrosion resistance and other special performance requirements. The use of continuous casting and liquid extrusion can produce up to several meters of cobalt-chromium tungsten wire, tungsten wire used to automatically fill in gas shielded arc welding, in order to improve efficiency and surfacing welding quality, while improving working conditions. Cast iron welding wire is sometimes used.

3, flux-cored

Roll into a thin strip round or shaped steel tubing, filled with a certain composition of the powder, made by drawing a seam flux cored wire, or steel pipe filled with a powder made of seamless flux cored wire drawing (see Figure). This Flux Cored Welding Wires with high deposition efficiency, adaptability of steel, a short trial period, so its use and use expanded. This wire is mainly used for carbon dioxide gas shielded arc welding, submerged arc and electroslag welding. The powder composition of flux-cored electrode drugs and skin generally similar. Containing slag, making the gas composition and stability of flux-cored arc welding without shielding gas, said the self-shielded flux cored wire, for large welded structure works.

4, the cold wire EDM

Special cold welding of EDM wire coating, applied at room temperature under welding or welding with, one second after the welding wire is characterized by the temperature does not exceed 40 degrees Celsius, continuous welding without high 80 degrees Celsius. Mainly used for heat-resistant parts that do not repair, welding stoppage time, temperature is controlled at 40 degrees Celsius, 0.4-0.5 mm in thickness, the maximum not higher than 100 degrees Celsius.
