This disclosure relates to weldability of steel alloys that provide weld joints which retain hardness values in a heat affected zone adjacent to a fusion zone and which also have improved resistance to liquid metal embrittlement due to the presence of zinc coatings.

Weldability improvements in advanced high strength steel

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.

Metal forming apparatus and process with resistance heating

A method for providing a controlled heating profile in an article being heated in a resistance heating process is provided. The method includes contacting the article with a plurality of electrodes, selecting a first correlated group that includes at least two electrodes, and establishing a flow of electrical current between the electrodes of the first correlated group. The method also includes selecting a second correlated group that includes at least two electrodes, the second correlated group differing from the first correlated group. A flow of electrical current is also established between the electrodes of the second correlated group for the purpose of providing a controlled heating profile for an article undergoing resistance heating.

Method and apparatus for the uniform resistance heating of articles

A structural supporting roof pillar for use in a vehicle including an elongated, interiorly hollowed and polygonal shaped body having a selected arcuate lengthwise configuration and corresponding in placement to at least one of an A, B, and C vehicle pillar. A first component supporting flange is integrally formed, such as by overlapping end portions of a roll formed body, and projecting in at least a partially lengthwise extending fashion from a given cross sectional location. A secondary component supporting flange is affixed to a further cross sectional location associated with the body, such as further by welding.

One-piece, tubular member with an integrated welded flange and associated method for producing

A continuous process for producing a shaped metal member from a feedstock comprising a flat web of metal includes a roll-forming station for shaping the web, a cutting station for cutting the shaped web into individual members, and a processing station for altering a physical characteristic of the metal comprising the members. The processing may include heat treating and/or shaping. The process may also be operable to carry out further operations such as marking, inspection, sorting and the like. Also disclosed is an apparatus for carrying out the process.

Continuous process for producing a shaped steel member

A system for delivering a coolant fluid to a workpiece has a reservoir for retaining the fluid, a pump for delivering fluid from the reservoir, a supply line in communication with the workpiece and a diverter valve. A bypass line is in communication with the diverter valve, and the valve may be utilized to deliver fluid from the reservoir to the workpiece or to bypass the workpiece and circulate fluid back to the reservoir. The system also includes a fluid return line for conveying fluid from the workpiece back to the reservoir.

Coolant delivery system and continuous fabrication apparatus which includes the system

A frame system for a motor vehicle includes a plurality of frame members each having a connector socket defined therein. The system further includes a connector having an outer profile configured to engage the sockets of two of the frame members so as to connect them in a fixed angular relationship. The connectors are composite bodies including a core member and an exterior body which covers at least a portion of the core member and defines a portion of the outer profile of the connector. Also disclosed are frames which employ the system and methods for manufacturing the frames.

Frame system for motor vehicle

A vehicle bumper system defined principally by outboard and inboard elongate beams which project transversely across the vehicle. The ends of the front and rear beams are joined by connecting points which function as energy-absorbing fulcrums or hinges, with the remainder of the front and rear beams initially being free of direct structural connection. The front beam is outwardly curved so that the center portions of the front and rear beams define a gap therebetween. The rear beam has connections to the vehicle at two points spaced transversely inwardly from the end connections, which connections define inboard fulcrum or hinge points. The front and rear beams are each formed as elongate monolithic structures, such as of high strength steel, and have configurations which enable them to nest one within the other in the longitudinal direction of the vehicle.
