Nickel based flux cored wires comprise a family of wires that can be used to weld and clad in those applications where nickel based solid wire For GMAW and stick electrodes for SMAW or equivalent composition are commonly used. Incorporate a slag system that enables significantly higher deposition rates when welding out-of-position versus solid wires or stick electrodes. Typical deposition rates are 2 1/2 to 2 times higher than GMAW with solid wire and 2-3 times higher than SMAW.
