  • Publication number: 20190232424
    Abstract: A hybrid weld joint for joining sheet metal pieces together. According to one example, the hybrid weld joint exhibits characteristics of both butt welds and lap joints and is used to create a tailor-welded blank assembly where at least one sheet metal piece is made of aluminum or an aluminum-based alloy. Such a tailor-welded blank assembly is particularly suitable for the automotive industry.

  • Patent number: 8715424
    Abstract: A method of removing material such as surface treatments, metal coatings, and other material layers from an edge region of a metal work piece where they could potentially contaminate a nearby weld. According to one embodiment, a scraper tool includes a body having a base portion and a tab portion, and several scraping elements attached to the base portion. During operation, the scraping elements scrape one or more surfaces of the edge region so that the depth to which the scraping element engage the metal work piece is generally affected by the amount of rotation of the scraper tool about a pivot axis.

  • Patent number: 8573021
    Abstract: A metal blank that includes a binder trim component having at least one cut edge with a non-linear section. The creation of the non-linear section simultaneously forms a corresponding section in a binder trim component of an adjacent metal blank so that binder material can be shared therebetween. This reduces the amount of scrap metal, as the binder trim component is subsequently cut off and discarded. Furthermore, the non-linear section can include one or more strategically placed formations, such as projections, recesses, flat sections, etc., that cause it to be non-uniform along its length and to be specifically tailored to the manufacturing requirements of the part being formed.
