Resistance welding wire SKD11

aluminumaluminum alloy

Aluminum and aluminum alloy welding wire is selected according to the type of base metal, the mechanical properties of the joint and the corrosion resistance requirements. In general, when welding aluminum and aluminum alloys, a thin plate similar to the chemical composition of the base metal is often used as a welding wire. For heat-treated reinforced aluminum alloys with a high tendency to weld hot cracks, it is mainly necessary to use a welding wire with good crack resistance. Common welding wire: SKD11 > 0.5～3.2mm HRC 56～58 Welding repair cold steel, metal stamping die, cutting die, cutting tool, forming die, workpiece hard surface, making argon welding rod with high hardness, wear resistance and high toughness, before welding Warm up and preheat, otherwise it will be prone to cracking. 63 degree blade edge welding wire> 0.5～3.2mm HRC 63～55, mainly used in welding broaching die, hot for high hardness mould, hot forging master die, hot die, screw die, wear resistant hard surface, high speed steel , the knife edge repair. SKD61 > 0.5～3.2mm HRC 40～43 Welded zinc, aluminum die-casting mold, good heat resistance and crack resistance, hot air die, aluminum copper hot forging die, aluminum copper die-casting die, good heat resistance, resistance Grinding, crack resistance. Generally, hot-pressing molds often have cracks in tortoise shells, most of which are caused by thermal stress, and are also caused by corrosion of surface oxidation or die-casting materials. Heat treatment is adjusted to proper hardness to improve their life. Hardness is too low or too high.
