S215是一种含铁的铝青铜焊丝,高强度、抗腐蚀、耐磨性能优良。
S215 is an iron-containing aluminum bronze welding wire with high strength, corrosion resistance and excellent wear resistance.
通常用于焊接类似成分的铝青铜、锰硅青铜、某些铜镍合金、铁基金属和异种金属。最通常的异种金属是铝青铜与钢、铜与钢的焊接。该焊丝也用于耐磨和耐腐蚀表面的堆焊。
Usually used for welding similar composition aluminum bronze, manganese silicon bronze, certain copper-nickel alloys, iron-based metals and dissimilar metals. The most common dissimilar metals are the welding of aluminum bronze and steel, and copper and steel. The welding wire is also used for surfacing welding on wear-resistant and corrosion-resistant surfaces.

1. 焊前必须清除工件焊接边缘及焊丝表面的氧化物、油污等污物,以免引起气孔,夹渣等缺陷,使焊缝性能降低。
2. 铝青铜的焊接和碳钢的堆焊时,薄件不需预热,厚件须预热200℃左右。
3. 由于在熔融的熔池中会形成氧化铝,故不推荐该焊丝用于氧燃气焊接方法,只用于惰性气体保护焊。
1. Before welding, the oxides and oil stains on the welding edge of the workpiece and the surface of the welding wire must be removed to avoid defects such as pores and slag inclusions, which will reduce the performance of the weld.
2. When welding aluminum bronze and surfacing of carbon steel, thin parts do not need to be preheated, and thick parts must be preheated at about 200°C.
3. As alumina will form in the molten pool, it is not recommended to use this wire for oxy-gas welding and only for inert gas shielded welding.
