Characteristics and Applications
The MSM-SNi6054 welding wire is mainly used for welding Inconel 690 alloy via MAG, MIG, TIG, CMT or plasma welding processes, as well as for surfacing on the surfaces of carbon steel and stainless steel to form a nickel-chromium corrosion-resistant alloy coating. Its high chromium content endows it with excellent resistance to stress corrosion cracking in pure water environments under radiation conditions. This product is also suitable for applications requiring resistance to oxidizing acid corrosion, and can be used for dissimilar material joining of Inconel and Incoloy alloys.
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.
