Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A tailor welded blank manufactured 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 composition providing an austenite structure at temperatures ranging from 800° C. to 950° C. 2. The tailor welded blank according to claim 1 , wherein the welded zone has a composition in which a base material and a coating layer of each of the coated steel plates are mixed with the filler wire. 3. A hot stamped component manufactured by hot stamping a 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. 4. The hot stamped component according to claim 3 , wherein each of the blank elements includes a boron steel plate having hardenability as a base material, and an Al—Si or Zn coating layer. 5. The hot stamped component according to claim 4 , wherein the filler wire has a higher amount of an austenite-stabilizing element than the base material of the coated steel plate. 6. The hot stamped component according to claim 5 , wherein the austenite-stabilizing element comprises C or Mn.
