Rolling class, most of the wire belongs to this category, including carbon steel wire, low alloy structural steel wire, alloy structural steel wire, stainless steel wire and non-ferrous metal wire. Common welding wire: SKD11 > 0.5~3.2mm HRC 56~58 welding and cooling for steel, metal stamping die, die-cutting, cutting tools, molding die, workpiece hard hard to produce a high hardness, wear resistance and high toughness of the argon electrode, welding before heating preheating, otherwise prone to cracking phenomenon. 63-degree edge edge welding Wire > 0.5~3.2mm HRC 63~55, mainly used in welding broach die, heat for high hardness mold, hot forging total mold, hot stamping die, screw mold, wear-resistant, high speed steel, edge repair. SKD61 > 0.5~3.2mm HRC 40~43 Welding zinc, aluminum die-casting mold, with good heat resistance and crack resistance, hot air die, aluminum-copper forging, aluminum-copper die-casting, with good heat, wear-resistant, crack resistance. Common hot-pressing mold often shell-like crack, mostly caused by thermal stress, but also because of surface oxidation or die-casting raw material corrosion, heat treatment to the appropriate hardness to improve its life, too low or too high hardness is not applicable. 70N > 0. $number. 0mm welding Wire characteristics and applications: the bonding of high hardness steel, zinc-aluminum die-casting die cracking, welding and reconstruction, iron/cast iron welding. Welding Wire
Can be directly surfacing a variety of cast iron/pig iron material, can also be used as a mold crack welding, the use of cast iron welding, as far as possible to lower the current, with a short distance of the arc welding, the steel part of the preheating, after welding heating and slowly cooling. 60e> 0.5~4.0mm characteristics and uses: Special welding high tensile steel joint, hard-faced production of the bottom, crack welding. High-strength welding wire, nickel-chromium alloy components, professional used to prevent cracking bottom welding, filling and playing the bottom, tensile strength, and repair of steel after welding cracking phenomenon. Tensile strength: $number n/mm² reach rate: 26%.Welding Wire
Some alloys, such as cobalt-chromium-tungsten alloys, cannot be forged, rolled, and wire-shaped, but are made by casting. It is mainly used for manual surfacing of workpiece surface to meet special performance requirements such as anti-oxidation, abrasion resistance and corrosion resisting at high temperature. The use of continuous pouring and liquid extrusion can produce a number of meters of cobalt-chromium-tungsten welding wire for automatic tungsten electrode gas shielded arc welding, in order to improve welding efficiency and the quality of surfacing layer, but also improve working conditions. Cast iron welding wire is sometimes used to repair.Welding Wire
