ABSTRACT:
A method for resistance welding zinc-coated steel members is described wherein at least one member comprises a copper layer intermediate the steel and the zinc coating. The copper layer melts during welding and seals fissures within the fused steel to produce a hermetic weld. The copper layer also protects exterior surfaces where the zinc coating is disrupted by the welding operation.
