  • Patent number: 9827633
    Abstract: A method for the preparation of steel sheets for fabricating a welded steel blank is provided. The method includes procuring at least two pre-coated steel sheets, each having a pre-coating of an intermetallic alloy layer, topped by a layer of aluminum metal or aluminum alloy or aluminum-based alloy. The sheets have a principal face, an opposite principal face, and at least one secondary face. The sheets are positioned so a gap between 0.02 and 2 mm exists between the secondary faces. The secondary faces face each other. The positioning of the first and second sheets defines a median plane perpendicular to the principal faces. Layers of metal alloy are removed by melting and vaporization simultaneously on the principal faces, in a peripheral zone of the sheets, the peripheral zones being the zones of the principal faces closest in relation to the median plane.

    Abstract: The invention provides a hot stamped structural component (20) for an automotive vehicle, such as a B-pillar, including a first part (22) formed of a high strength steel material joined to a second part (24) formed of a high ductility steel material. The structural component (20) also includes a locally tempered transition zone (26) along the joint (28) to reduce the potential for failure along the joint (28). The transition zone (26) has strength and ductility levels between the strength and ductility levels of the remaining portions of the first and second parts (22, 24). The tempering step can be incorporated into a laser trimming cell or assembly cell, and thus the transition zone (26) can be created without adding an additional process step or increasing cycle time.

  • Publication number: 20140112709
    Abstract: A dissimilar material joint is formed by arranging a plurality of joint segments consecutively in a longitudinal direction. Each joint segment is formed by joining and integrating together a first member, an intermediate member, and a second member by explosive welding. A groove is formed in a joint end face of each joint segment, the joint end face being joined to another one of the segments, the groove spacing apart an end face of the first member and an end face of the second member from each other in a stacking direction. In the dissimilar material joint, the end faces of the respective first members of the joint segments that are adjacent to each other are joined together by welding, and the end faces of the respective second members of the joint segments that are adjacent to each other are joined together by welding.
