S223是含少量锡的黄铜焊丝,熔点约900℃,熔融金属具有良好的流动性,焊缝金属具有一定的强度和耐蚀性。
S223 is a brass welding wire with a small amount of tin with a melting point of about 900°C. The molten metal has good fluidity, and the weld metal has certain strength and corrosion resistance.
主要用于火焰、炉中、感应等方法的铜、钢及镍的钎焊,也可用于铜、铜镍合金的熔化极气体保护电弧焊和惰性气体保护电弧焊。
It is mainly used for brazing of copper, steel and nickel in flame, furnace, induction and other methods. It can also be used for molten electrode gas shielded arc welding and inert gas shielded arc welding of copper and copper-nickel alloys.

1. 焊前必须仔细清洁焊件被焊部位及焊丝表面。
2. 焊件一般预热到400~500℃后施焊,非惰性气体保护焊时一般须配铜气、钎焊熔剂使用。
1. Before welding, the welded parts and the surface of the welding wire must be carefully cleaned.
2. The weldment is generally preheated to 400~500℃ and then welded. Generally, copper gas and brazing flux must be used for non-inert gas shielded welding.
