Characteristics and Applications
The MSM-SNi6022 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. Thanks to the weld metal’s excellent resistance to preferential corrosion, and its high chromium and molybdenum content that also endows it with outstanding pitting and crevice corrosion resistance, this welding wire is also widely applied in welding molybdenum-containing stainless steel and Inconel C-276 alloy. The MSM-SNi6022 welding wire can be used for dissimilar material welding, such as joining Inconel series alloys, Incoloy series alloys, carbon steel, low-alloy steel and stainless steel.

Precautions
1.MIG, TIG or other applicable welding processes can be adopted. The shielding gas shall be pure argon, argon-rich mixed gas or other applicable gases.
2.Thoroughly remove oil stains, moisture, dust, oxide films and other contaminants from the groove and its adjacent areas before welding.
3.A reliable wind-shielded facility shall be provided at the welding site to avoid diminishing the shielding effect of the gas.
4.For multi-layer and multi-pass welding, the interpass temperature shall not exceed 100℃.
5.When using non-consumable electrode filler wire welding processes such as TIG, plasma welding and laser welding, the shielding gas shall be 99.99% argon.
