AWS A5.11 ENiCrMo-6       

Description: Ni327 -6 is a nickel-based electrode with low-hydrogen sodium coating. Use DCEP (direct current electrode positive). The deposited metal has excellent plasticity, toughness and crack resistance. Deposited metal has a linear expansion coefficient similar to that of steel, and has high strength and strong corrosion resistance at room temperature and high temperature. Application: It is used for the welding of Ni9% steel, and can also be used for welding of dissimilar steels and difficult-to-weld alloys.   Chemical composition of weld metal(%):

  Notice: 1. The electrode must be baked for1 hour at around 300℃ before welding operation. Try to use a short arc to weld; 2. It is essential to clean up rusty, oil, water, and impurities on welding parts before welding. 3. Try to use small line energy when welding, multi-layer and multi-pass welding.
