Method of Producing Solid Wire for Welding. This invention describes an in-line process for efficiently producing copper-plating-free solid welding wire. Roller dies draw the stock wire at high speed using a dry solid lubricant containing sodium stearate, potassium stearate, or both. A washing device then removes lubricant from the wire, and an oiling device applies a lubricant for wire feeding. These steps produce wire at or near its finished diameter.

Wire for Welding. This patent concerns plated or unplated solid wire and flux-cored wire for carbon or stainless steel. It describes depositing selected hydrocarbon compounds on the wire surface and using them to chemically combine lubricating oil or particles with that surface. The specified total deposit of hydrocarbons and lubricant is 0.1 to 5 grams per 10 kilograms of wire.
