说明：
S911是含有少量Mn以及Fe、Ti的镍铜焊丝。耐蚀，可焊性好。
S911 is a nickel-copper welding wire containing a small amount of Mn, Fe and Ti. Corrosion resistance and good weldability.
用途：
适用于镍-铜合金本身以及与钢的焊接，也可用于镍-铜合金复合钢覆层一侧的焊接或在钢上堆焊。
It is suitable for the welding of nickel-copper alloy itself and steel. It can also be used for welding on one side of nickel-copper alloy composite steel cladding or surfacing welding on steel.

注意事项：
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.采用钨极氩弧焊时宜采用直流正接。焊较厚板时可以选用熔化极氩弧焊，采用直流反接或交流施焊。
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 using tungsten argon arc welding, DC positive connection should be adopted. When welding thicker plates, argon arc welding with melting pole can be used, and DC reverse welding or AC welding can be used.
