ENiCrMo-3 Welding Electrode
1. Description
ENiCrMo-3 is a nickel-based electrode with a low hydrogen type coating. The weld has excellent plasticity, toughness and crack resistance. Weld metal has high strength and good corrosion resistance at room temperature and high temperature. DC reverse connection, good welding process performance, good operability, good all-position weldability.
2. Application
ENiCrMo-3 welding electrode are used for nickel-base alloy welding, and can also be used for welding and surfacing of difficult-to-weld alloys and dissimilar steels.
3. Standard
(1). AWS ENiCrMo-3
(2). GB/T13814 ENi6625
4. Attention
(1). The electrode before welding shall be baked at 350 ° C for 1 hour before use and used with baking.
(2). Before welding, the weldment must be clear of rust, oil, moisture and other impurities.
