S901 纯镍焊丝
标准:
符合GB SNi2061
相当AWS ERNi-1
说明:
S901是含有适量Ti的特殊纯镍焊丝。加入一定量的钛脱氧可防止焊缝金属产生气孔,并能改善组织,从而获得优良的焊接接头。
S901 is a special pure nickel welding wire with appropriate amount of Ti. Adding a certain amount of titanium to deoxidize can prevent the weld metal from producing pores, and can improve the structure, so as to obtain an excellent welded joint.
用途:
用于工业纯镍的氩弧焊,也适用于镍复合钢板的焊接,以及铜合金、不锈钢、高镍合金等与纯镍的异种金属焊接。
It is used for argon arc welding of industrial pure nickel, and also suitable for welding of nickel clad steel plates, and welding of dissimilar metals such as copper alloys, stainless steels, high nickel alloys and pure nickel.

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.
