HS221 is a special brass welding wire containing a small amount of tin and silicon. The melting point is about 890 degrees Celsius. Tin can improve the fluidity, strength, and corrosion resistance of welding wire, while silicon can effectively control the evaporation of zinc, eliminate pores, and achieve satisfactory mechanical properties. Brass is used as a filling material in oxyacetylene gas welding and carbon arc welding, and is also widely used in brazing copper, steel, copper nickel alloys, gray cast iron, and embedded hard alloy cutting tools, with a wide range of applications. Attention: 1. Before welding, the groove of the welded part and the surface of the welding wire must be carefully cleaned. 2. Preheat to 400-500 degrees Celsius before welding. Copper gas welding solvent must be used as a solvent during welding. 3. The welding flame should use a neutral flame or a slight oxidizing flame, appropriately reduce the temperature during welding, increase the welding speed, and minimize the residence time of the molten pool at high temperatures to reduce the evaporation and oxidation of zinc.
