Characteristics and Applications
The MSM-SNi8065 welding wire is mainly used for welding Incoloy 825 alloy and other nickel-iron-based alloys with similar nickel-iron-chromium-molybdenum-copper compositions via MAG, MIG, TIG, CMT or plasma welding processes. The weld metal formed by this welding material exhibits excellent corrosion resistance, and is particularly resistant to corrosion by reducing chemicals such as sulfuric acid and phosphoric acid.
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.
