Classification Of Welding Wire

   The wire is used as a filler metal or as a conductive wire for welding. In the gas welding and tungsten gas protection arc welding, the wire used as a filler metal; in submerged arc welding, electroslag welding and other melting gas protection arc welding, the welding wire is both filled with metal, but also conductive electrodes. The surface of the wire is not coated with an oxidative flux.Welding Wire Rolling, most of the welding wire belongs to this category, including carbon steel wire, low alloy structural steel wire, alloy steel wire, stainless steel wire and non-ferrous metal wire. Common welding wire:

SKD11> 0.5 ~ 3.2mm HRC 56 ~ 58 welding cold steel, metal stamping die, die, tool, forming mold, the workpiece hard surface with high hardness, wear resistance and high toughness of the argon electrode, welding before the first Heating preheating, or easy to produce cracks.Welding Wire 63 degrees knife edge welding wire> 0.5 ~ 3.2mm HRC 63 ~ 55, mainly used in welding knife mold, hot for high hardness with mold, hot forging the total mold, hot die, screw mold, wear hard surface, high speed steel , Knife repair. SKD61> 0.5 ~ 3.2mm HRC 40 ~ 43 welding zinc, aluminum die-casting mold, with good heat resistance and resistance to cracking, hot stamping die, aluminum and copper hot forging die, aluminum die-casting mold, with good heat resistance Grinding, crack resistance. General hot die casting mold is often tortoise shells, most of which is caused by thermal stress, but also due to surface oxidation or die-casting raw materials caused by corrosion, heat treatment to adjust the appropriate hardness to improve its life, hardness is too low or too high Be applicable. 70N> 0.1 ~ 4.0mm Wire Features and Uses: High hardness steel bonding, zinc aluminum die casting mold cracking, welding reconstruction, pig iron / cast iron welding. Can be directly surfing a variety of cast iron / pig iron material, but also as a mold cracking of the welding, the use of cast iron welding, as far as possible the current down, with a short distance arc welding, steel part of the preheat, after welding The heating and slowly cooling.Welding Wire 60E> 0.5 ~ 4.0mm Features and Uses: special welding high tensile strength of the bonding, hard surface production of the bottom, the welding of the cracks. High-strength wire, nickel-chromium alloy with high composition, professional for anti-rupture of the bottom of the welding, filling the bottom with a strong pull, and can repair the phenomenon of steel after welding cracks. Tensile strength: 760 N / mm & sup2; Tendency: 26% 8407-H13> 0.5 ~ 3.2mm HRC 43 ~ 46 Zinc, aluminum, tin and other non-ferrous alloy and copper alloy die-casting mold, can be used as hot forging or stamping die. High toughness, abrasion resistance and good heat resistance, high temperature softening, high temperature fatigue resistance, welding hot make punch, reamer, rolling knife, grooving knife, scissors ... and so do heat treatment , To prevent decarburization, hot tool steel after welding the hardness is too high prone to rupture. - anti-bursting wire> 0.5 ~ 2.4mm HB ~ 300 high hardness of the steel joint, hard surface production of the bottom, the welding of the crack. High-strength wire, nickel-chromium alloy with high composition, for the prevention of rupture of the underlying welding, filling the base, Rally strong, and repair steel cracking welding reconstruction.Welding Wire
