10PCs Welding Rods Wires Sticks Tin Brass Wire For Brazing Soldering Repair^VV

Description

Features:
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.
Widely use:
Brass oxyacetylene gas welding and carbon arc welding, used as a filler material, also widely used in brazing copper, steel, copper-nickel alloy, gray cast iron and inlaid carbide tools, etc., with 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. Generally preheat to 400-500 degrees Celsius before welding. 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.
