Applications • First Stage Turbine Blades & Lower Temp • Sheet applications such as exhaust case & Burner liners • Medical Implants

Resistance Welding The resistance welding manual says: Cobalt alloys can be spot, seam and flash welding with conditions similar to that of Nickel. But they also say data is limited. RWMA concludes: current requirements will be no more than for SS, but slightly higher welding forces will be required. Welding time should also be about the same.
