Title: Steel welding electrode wire - coated with a very thin film of rust-inhibitor and oil for corrosion protection
IPC: B23K35/02
Filed: 1974-08-29
Abstract: This consumable electrode wire is made of ferrous metal and has an ultra-thin coating on its surface, the coating consisting of a monomolecular layer of a passive prod. resulting from the chemical reaction of an inhibitor with the wire surface. The coating may also contain a residual layer of a hydrocarbon liq., so thin that the layer feels dry when touched, and with an evapn. pt. lower than the welding temp. so the layer evaporates when the wire is heated for welding. The inhibitor, with or without the hydrocarbon liq., is pref. applied using a readily volatile solvent to give a final coating 10 mu thick. The wire can be made of carbon-, alloy-, or stainless steel. Not only prevents corrosion of the welding wire but also the excessive wear or jamming of the feeding mechanism and the wire-guides, two defects which frequently occur with the conventional Cu coating which tends to flake and peel off.
