Equivalent to: GB/T 15620 SNi6276 AWS A5.14 ERNiCrMo-4 ISO 18274 SNi6276
Characteristics and Applications
MSM-WNi6276 welding wire is mainly used for welding Inconel C-276 alloy and other nickel-chromium-molybdenum alloys via MAG, MIG, TIG, CMT or plasma welding processes, and it can also be applied to surfacing welding on steel surfaces. This welding material demonstrates excellent corrosion resistance in various aggressive media, especially outstanding resistance to pitting corrosion and crevice corrosion. The welding wire is suitable for dissimilar material welding, including the joining of Inconel C-276 alloy with other nickel alloys, stainless steels and low-alloy steels.
Precautions
1.When using MIG, TIG or other applicable welding processes, the shielding gas can be pure argon, argon-rich mixture gas or other suitable gases.
2.Thoroughly clean oil stains, moisture, dust, oxide films and other contaminants from the groove and its adjacent areas before welding.
3.The welding site shall be equipped with effective wind shielding to prevent the reduction of shielding gas performance.
4.For multi-pass welding, the interpass temperature shall not exceed 100℃.
5.When conducting non-consumable electrode filler wire welding (e.g., TIG, plasma, laser welding), the shielding gas shall be 99.99% pure argon.
