Cobalt

Cobalt Superalloys are used in turbine blades for Gas Turbine engines due to their high temperature strength, oxidation resistance and wear resistance. Welding cobalt alloys should not be difficult once the correct method and filler wire is used.


To avoid crack susceptible microstructures a compatible filler metal should be selected, this is especially important when welding dissimilar base metals. Contact the VBC Technical Team for assistance on the best filler wire for your application at tech@vbcgroup.com
