摘要： The invention provides a method of manufacturing a component formed of an aluminum alloy for use in an automotive vehicle application, for example those requiring high strength, light-weight, and a complex three-dimensional shape. The method begins by providing a blank formed of an aluminum alloy which is already solution heat treated and tempered, and thus has a temper designation of about T4. The method further includes heating the blank to a temperature of 150° C. to 350° C., preferably 190° C. to 225° C. The method next includes quickly transferring the blank to a hot or warm forming apparatus, and stamping the blank to form the complex three-dimensional shape. Immediately after the forming step, the component has a temper designation of about T6, but preferably not greater than T6, and thus is ready for use in the automotive vehicle application without any post heat treatment or machining.

摘要： A method for manufacturing a hot formed part (20), such an automotive body component, is provided. The method includes heating a steel blank (22) to an austenite temperature, and quickly transferring the heated blank (22) to a hot forming apparatus (28). The method then includes forming the heated blank (22) between a pair of dies (24, 26), and trimming, piercing, shearing, or otherwise cutting the heated blank (22) or hot formed part (20) in the hot forming apparatus (28). The cutting step occurs while the microstructure of the steel blank (22) is substantially austenite, for example at a temperature of 400° C. to 850° C. The method can provide a hot formed part (20) having a desired shape in a single die stroke, without the need for a costly post-forming operation outside of the hot forming apparatus (28), such as laser trimming.
摘要翻译：提供了一种制造这种汽车车身部件的热成型部件（20）的方法。该方法包括将钢坯（22）加热至奥氏体温度，并将加热的坯料（22）快速转移到热成型装置（28）。该方法然后包括在一对模具（24,26）之间形成加热的坯料（22），并且在热成形设备中修剪，刺穿，剪切或以其他方式切割加热的坯件（22）或热成形部分（20）（28）。当钢坯（22）的微观结构基本上为奥氏体时，例如在400℃至850℃的温度下，发生切割步骤。该方法可以提供具有期望形状的热成形部件（20）单模冲程，而不需要在热成型装置（28）之外的昂贵的后成形操作，例如激光修整。

摘要： The present invention relates generally to laser welding in the manufacture of sheet metal components, such as for example automobile components. More particularly, the present invention relates to a process and a system for forming a localized anti-corrosion surface layer along a laser welded joint (weld bead), subsequent to the laser welding together of sheet metal plates having an anti-corrosion surface layer pre-coat.

摘要： A process is described for laser welding a sheet metal workpiece having an aluminum-silicon containing pre-coat layer disposed on at least one major surface thereof, and having first and second opposite side edges. The sheet metal workpiece is arranged such that the first and second side edges are in contact with one another and such that the at least one major surface faces outwardly. A closed tube-shaped product is obtained by forming a laser-weld joint between the first and second side edges. In particular the laser-weld joint is formed absent removing the aluminum-silicon containing layer from along the adjacent edges, such that aluminum from the aluminum-silicon containing layer enters into the melt pool that is formed. An alloying material is introduced into the melt pool during laser welding and forms a compound with at least some of the aluminum in the melt pool.

摘要： A process is disclosed for laser-welding sheet metal plates that have an aluminum-silicon containing pre-coat layer. The pre-coated sheet metal plates are arranged one relative to another such that an edge of one of the plates is adjacent to and in contact with an edge of the other one of the plates, and a laser-welded joint is formed along the adjacent edges of the pre-coated plates. In particular the joint is formed absent removing the aluminum-silicon containing layer from along the adjacent edges, such that aluminum from the aluminum-silicon containing layer enters into the melt pool that is formed. Additionally, an alloying material is introduced into the melt pool during forming the laser-welded joint and forms a compound with at least some of the aluminum in the melt pool.

摘要： A process is described for laser welding a sheet metal workpiece having an anti-corrosion pre-coat on at least one major surface thereof and having first and second opposite side edges. The sheet metal workpiece is arranged such that the first and second side edges are in contact with one another and such that the at least one major surface faces outwardly. A laser beam having a first beam spot-size, is used to form a laser weld joint between the first and second side edges. Subsequently, a localized anti-corrosion surface layer is formed on the laser weld joint. To this end, a laser beam having a second beam spot-size larger than the first beam spot-size is scanned along the laser weld joint. During the scanning, a flow of a powdered anti-corrosion surface layer material is directed toward a portion of the laser weld joint that is being irradiated by the laser beam. The laser beam melts the material, which subsequently solidifies to form a layer adhering to the laser weld joint.

摘要： A process is described for laser welding a sheet metal workpiece having an anti-corrosion pre-coat material on at least one major surface thereof. The sheet metal workpiece is arranged such that first and second side edges are in contact with one another and the coated major surface faces outwardly. A first laser beam having a first beam spot-size is used to form a laser weld joint between the first and second side edges. A second laser beam having a second beam spot-size larger than the first beam spot-size is then scanned along the laser weld joint and is tilted in a tilt direction parallel to the scanning direction to produce an elongated beam spot. During the scanning, a flow of a powdered anti-corrosion surface layer material is directed toward a portion of the laser weld joint that is being irradiated by the second laser beam. The second laser beam melts the material, which forms a layer adhering to the laser weld joint.
