S211是含少量锰的硅青铜焊丝。熔点约为910~1025℃,塑性好。由于锰的加入,焊接后具有良好的力学性能、抗腐蚀性能和耐磨性能。具有良好的工艺性能。
S211 is a silicon bronze welding wire with a small amount of manganese. The melting point is about 910~1025℃, and the plasticity is good. Due to the addition of manganese, it has good mechanical properties, corrosion resistance and wear resistance after welding. Has good process performance.
用于硅青铜、紫铜、黄铜及铝青铜的氩弧焊,也可用于铜和铸铁的氩弧焊及堆焊,铜与钢的焊接。如汽车门框、摩托车零件的氩弧钎焊,机车车辆、重型机器摩擦面的堆焊。
It is used for argon arc welding of silicon bronze, red copper, brass and aluminum bronze. It can also be used for argon arc welding and surfacing welding of copper and cast iron, and the welding of copper and steel. Such as argon arc brazing of automobile door frames and motorcycle parts, and surfacing of friction surfaces of locomotives and heavy machinery.

1. 焊前必须清除工件焊接边缘及焊丝表面的氧化物、杂质等。
2. 焊接接头板厚小于3mm时,不开坡口;板厚为3~10mm时,开60°~70°V型坡口;板厚大于10mm时,开60°~70°X型坡口。
3. 推荐TIG焊采用直流正极性或交流,MIG焊采用直流反极性,为了避免出现热裂纹,层间温度最好控制在65℃以下。
1. The oxides and impurities on the welding edge of the workpiece and the surface of the welding wire must be removed before welding.
2. When the plate thickness of the welded joint is less than 3mm, no groove; when the plate thickness is 3~10mm, open a 60°~70°V groove; when the plate thickness is greater than 10mm, open a 60°~70°X groove .
3. It is recommended to use DC positive polarity or AC for TIG welding, and DC reverse polarity for MIG welding. In order to avoid thermal cracks, the temperature between layers should be controlled below 65℃.
