DUAL WIRE WELDING OR ADDITIVE MANUFACTURING CONTACT TIP AND DIFFUSER

摘要

A welding or additive manufacturing contact tip (200, 700) includes an electrically-conductive body extending from a proximal end of the body to a distal end of the body. The body forms a first bore terminating at a first exit orifice (701, 702) at a distal end face of the body, and a second bore terminating at a second exit orifice (701, 702) at the distal end face of the body. The first and second exit orifices (701, 702) are separated from each other by a distance configured to facilitate formation of a bridge droplet between a first wire electrode (E1, E2) delivered through the first bore and a second wire electrode (E1, E2) delivered through the second bore during a deposition operation.
