| 发明名称 | Tailor welded blank, manufacturing method thereof, and hot stamped component using tailor welded blank | ||
| 摘要 | 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. | ||

| 主权项 | 1. A method of manufacturing a tailor welded blank, comprising: laser-welding blank elements made of coated steel plates having different strengths or thicknesses using a filler wire, wherein the filler wire has a composition system in which a welded zone does not generate a ferrite structure at temperatures ranging from 800° C. to 950° C., by taking intrusion of a composition of coating layers of the coated steel plates into the welded zone into account. | ||
