S222是含少量铁、锡、硅、锰等元素的特殊黄铜焊丝,熔点约860℃。流动性较好,硅可有效地抑制锌的蒸发、消除焊缝气孔和得到满意的机械性能。
S222 is a special brass welding wire with a small amount of iron, tin, silicon, manganese and other elements, with a melting point of about 860°C. Good fluidity, silicon can effectively inhibit the evaporation of zinc, eliminate weld pores and obtain satisfactory mechanical properties.
黄铜氧-乙炔气焊及碳弧焊时作为填充材料。也可用于钎焊铜、钢、铜镍合金、灰口铸铁以及镶嵌硬质合金刀具等。
Brass oxygen-acetylene gas welding and carbon arc welding are used as filler materials. It can also be used for brazing copper, steel, copper-nickel alloy, gray cast iron and inlaid carbide tools.

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,氧-乙炔火焰焊时必须配铜气焊熔剂使用。
3. 焊接火焰应采用中性焰或轻微的氧化焰,适当降低焊接温度,提高焊接速度,尽量减少熔池在高温下的停留时间,以减少锌的蒸发和氧化。
1. Before welding, the welded parts and the surface of the welding wire must be carefully cleaned.
2. Welding parts are generally preheated to 400~500℃ and then welded. Oxygen-acetylene flame welding must be used with copper gas welding flux.
3. The welding flame should be a neutral flame or a slight oxidizing flame, reduce the welding temperature appropriately, increase the welding speed, and minimize the residence time of the molten pool at high temperatures to reduce the evaporation and oxidation of zinc.
