ABSTRACT:
An apparatus for forming a metal article includes a station which receives and supports a workpiece. The station has a source of electrical current and a source of a fluid. The station further includes a first and a second electrode clamp. Each clamp is in electrical communication with the source of current and in fluid communication with the source of fluid. The clamps engage a workpiece and deliver an electrical current and a fluid thereto. The system includes an actuator mechanically associated with at least one of the clamps. The actuator is operable in combination with a clamp to apply mechanical force to the workpiece. The system is operable to selectably control the temperature profile and/or ambient conditions of a workpiece during forming or processing steps. Disclosed are specific systems including modular systems. Also disclosed are methods for using the systems.
