  • Patent number: 9884468
    Abstract: Disclosed are a tailor welded blank and a manufacturing method thereof. The tailor welded blank is manufactured by connecting blank elements of different materials or thicknesses, thereby eliminating quality problems in a welded zone. A hot stamped component is manufactured by hot stamping the tailor welded blank formed by laser-welding blank elements made of coated steel plates having different strengths or thicknesses using a filler wire, wherein a laser-welded zone has a martensite structure.
    Type: Grant

  • Patent number: 8555507
    Abstract: As to the method for fabricating a member of a vehicle, after a member for the vehicle having high-rigidity of martensite organization is fabricated by a hot stamping forming, the martensite organization is transformed to a ferrite having a low-rigidity partially and improved toughness or to a metal organization heat treated by tempering process through induction heating or secondary heat treatment using laser beam of conduction area, and thereby collision absorption performance is improved by stabilizing the absorption directivity of the collision energy without additional reinforcement.

  • Patent number: 7988908
    Abstract: Provided is a filler metal alloy composition capable of improving appearance of a welded zone and fluidity, penetration, etc., of an inexpensive filler metal by minimizing a content of silver (Ag) and adding tin (Sn) and silicon (Si) components. The filler metal alloy composition, brazed to a joint between parent metals to stably join the parent metals formed of the same material or different materials, is characterized in that the composition comprises silver (Ag), copper (Cu), zinc (Zn), tin (Sn), silicon (Si), and other unavoidable impurities.
