Equivalent to: GB/T 15620 SNi6022 AWS A514 ERNiCrMo-10 ISO 18274 SNi6022
Characteristics and Applications
MSM-WNi6022 welding wire is mainly used for welding Inconel 622/625 alloys and Incoloy 25-6Mo/825 alloys via MAG, MIG, TIG, CMT or plasma welding processes. Benefiting from its high chromium and molybdenum content, the weld metal exhibits excellent resistance to preferential corrosion, pitting corrosion and crevice corrosion. Therefore, it is also widely applied in welding molybdenum-containing stainless steels and Inconel C-276 alloys. TP-WNi6022 welding wire is suitable for dissimilar material welding, such as joining Inconel series alloys, Incoloy series alloys with carbon steels, low-alloy steels and stainless steels.
Precautions
1.When adopting 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 avoid compromising the 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.
