Construction site Brass welding rods Strong solder joints HS221 tin brass

 HS221 is a special brass welding wire with 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 the welding wire, while silicon can effectively control the evaporation of zinc, eliminate pores and obtain satisfactory mechanical properties.

Brass oxyacetylene gas welding and carbon arc welding are used as filler materials. It is also widely used in brazing copper, steel, copper-nickel alloy, gray cast iron and inlaid carbide tools, etc., and has a wide range of uses.

Precautions:

1. The groove of the weldment and the surface of the welding wire must be carefully cleaned before welding.

2. Before welding, it is generally preheated to 400-500 degrees Celsius before welding. The copper gas welding solvent must be used as the solvent when welding.

3. The welding flame should be a neutral flame or a slight oxidizing flame. The temperature during welding should be appropriately reduced, the welding speed should be increased, and the residence time of the molten pool at high temperatures should be minimized to reduce the evaporation and oxidation of zinc.
