Abstract: The concepts described herein provide a method, system, and apparatus for joining, via welding, first and second members fabricated from an aluminum alloy including aluminum, zinc, and manganese, such as 7000-series aluminum alloys, and a resultant workpiece. A junction is formed by a first member being disposed contiguously to a second member. A welding machine generates a weld pool at the junction that includes liquified aluminum alloy. An ultrasonic transducer directs ultrasonic energy in proximity to the weld pool. In some embodiments, an electro-magnetic transducer directs electro-magnetic energy in proximity to the weld pool. The first member is fused to the second member at the junction upon solidification of the weld pool.

Abstract: A method of forming a component includes providing a work-piece blank from a formable material. The method also includes engaging the work-piece blank with a transfer device. The method additionally includes austenitizing the work-piece blank in the transfer device via heating the blank to achieve austenite microstructure therein. The method also includes transferring the austenitized blank to a forming press using the transfer device. The method additionally includes forming the component via the forming press from the austenitized blank and quenching the formed component. A work-piece blank transfer system includes a transfer device having clamping arm(s) for engaging, holding, transferring, and releasing the work-piece blank. The transfer device also includes a heating element configured to austenitize the work-piece blank via heating the blank to achieve austenite microstructure therein. The transfer system additionally includes an electronic controller programmed to regulate the heating element and the clamping arm(s).

Abstract: A method to achieve variable properties of a component using a coating free press hardened steel comprises: transferring a blank of a coating free press hardened steel (CFPHS) material having base blank properties into a heating unit having multiple induction heating coils; heating the blank within the heating unit to create a modified blank having differing modified blank properties throughout the modified blank compared to base blank properties; moving the modified blank out of the heating unit into a die; and forming a shaped part by operation of the die creating a finished CFPHS part.

Abstract: A method of assembling a vehicle component, a system for assembling a vehicle component, and a vehicle component assembly. A blank is formed from a steel sheet, wherein the steel sheet includes a coating on a surface. The coating is removed from a first interface surface of the blank and the blank is stamped either prior to or after removing the coating. The first dynamic interface surface is arranged relative to a second interface surface and thermally joined to form a joint.

Abstract: A hot formed joined blank includes a first metal blank having an ultimate tensile strength of ≥about 1300 MPa to ≤about 2000 MPa and defining a first surface, a second metal blank having an ultimate tensile strength of ≥about 400 MPa to ≤about 1200 MPa and defining a second coated surface having a coating disposed thereon. The coating includes aluminum and silicon or in alternative variations, zinc. A third surface of the second metal blank is joined to the first surface of the first metal blank to form the hot formed joined blank. A weld nugget is disposed along a boundary between the first and second metal blanks that is configured to join the first and second metal blanks, where the weld nugget optionally includes less than or equal to about 1.5 weight percent aluminum or a microstructure comprising austenite and delta-ferrite.

Abstract: A sheet blank includes a core substrate having a generally planar shape with opposed first and second sides. The core substrate is made of high-strength steel containing at least two of ferrite, martensite, bainite, and austenite and having an ultimate tensile strength of at least 490 MPa. A respective decarburized layer of the high-strength steel is formed on each of the first and second sides of the core substrate, wherein each respective decarburized layer contains a minimum ferrite content of at least 80 volume % ferrite and has a respective thickness of 5 to 100 microns. A respective transition layer of the high-strength steel may be formed between the core substrate and each respective decarburized layer, with each transition layer having a respective inner transition layer abutting the core substrate and a respective outer transition layer abutting the respective decarburized layer.
