Understand the relevant knowledge of the welding wire in the welding wire machine

The most important part of the wire welding machine is the welding wire. The welding wire is used as a filler metal or as a wire welding material for conducting electricity at the same time. Please follow our wire welding machine manufacturer to learn more about welding wire.

In gas welding and tungsten gas shielded arc welding, the welding wire is used as the filler metal; in submerged arc welding, electroslag welding and other molten electrode gas shielded arc welding, the welding wire is both the filler metal and the welding wire is also the conductive electrode. The surface of the welding wire is not coated with anti-oxidation flux.

Welding wire classification

Rolling

Most welding wires fall into this category, including carbon steel welding wire, low-alloy structural steel welding wire, alloy structural steel welding wire, stainless steel welding wire and non-ferrous metal welding wire, etc.

Common welding wire:

Explosion-proof bottoming welding wire: bonding of high-hardness steel, bottoming of hard surface production, and welding of cracks. High-strength welding wire with high content of nickel-chromium alloy. It is used for anti-cracking bottom welding, filling and bottoming. It has strong tensile force and can repair cracks and welds of steel.

Oil-steel welding wire: blanking dies, gauges, drawing dies, perforation punches, can be widely used in hardware cold stamping, hand-decoration embossing dies, etc., general-purpose special tool steel, wear-resistant, oil-cooled.

High-speed steel welding wire: High-speed steel, the durability is 1.5 to 3 times that of ordinary high-speed steel, suitable for manufacturing and processing high-temperature alloy, stainless steel, titanium alloy, high-strength steel and other difficult-to-process materials, welding broach, hot work high hardness Tools, molds, hot forging master molds, hot stamping dies, screw dies, wear-resistant hard surfaces, high-speed steel, punching tools, cutting tools, electronic parts, thread rolling dies, dental plates, drill rollers, rolling dies, compressor blades and Various molds, mechanical parts, etc. It has undergone strict quality control of European industrial standards, high carbon content, good composition, uniform internal organization, stable hardness, wear resistance, toughness, and high temperature resistance. The characteristics are better than those of general materials of the same grade.

Casting

Some alloys cannot be forged, rolled, or wire drawn, but are made by casting methods. It is mainly used for manual surfacing of work piece surfaces to meet special performance requirements such as oxidation resistance, wear resistance and corrosion resistance at high temperatures. Continuous casting and liquid extrusion can produce cobalt-chromium-tungsten welding wire up to several meters, which can be used for automatic filling tungsten gas shielded arc welding to improve welding efficiency and quality of surfacing layer, and at the same time improve working conditions.

Drug core

Thin steel strips are rolled into round or special-shaped steel pipes, filled with powder of a certain composition, and drawn into seam flux-cored wires, or steel pipes are filled with powder and drawn into seamless flux-cored wires. This kind of welding wire has high welding and deposition efficiency, good adaptability to steel, and short trial production cycle, so its usage and scope of use continue to expand. This kind of welding wire is mainly used for carbon dioxide gas shielded welding and submerged arc welding.
