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.
