全球领先钢铁和矿业公司安赛乐米塔尔（ArcelorMittal）的下属子公司安赛乐米塔尔激光拼焊板（AMTB）于7月1日庆祝其北美生产制造的第300万片激光拼焊钢制门环下线。此第300万片门环于下午3点在AMTB底特律工厂制成。
ArcelorMittal Tailored Blanks (AMTB), a subsidiary of ArcelorMittal, the world’s leading steel and mining company, celebrated the production of three million laser-welded steel door rings for AMTB’s Americas region on July 1st. The three millionth door ring was made at AMTB Detroit at 3 P.M.
安赛乐米塔尔激光拼焊板北美总裁兼首席执行官Todd Baker表示：“我感到非常自豪，我们在北美地区已生产出300万个门环，且此项生产记录在最先进的底特律工厂诞生。这一成就证明，门环已成为汽车制造商提高车辆性能和安全性的关键工具，可同时降低车辆重量和生产成本。这也证明了AMTB整个团队的辛勤工作、奉献精神和担当，他们使这一‘行业首创’成为可能。”
“I am immensely proud that we have produced three million door rings in our Americas region, with the record door ring happening at our state-of-the-art facility in Detroit,” said Todd Baker, president and CEO, ArcelorMittal Americas. “This achievement is a testament to how the door ring has become a key tool for automakers in improving vehicle performance and safety, while reducing vehicle weight and cost. It’s also a testament to the hard work, dedication and commitment of the entire AMTB team, who made this ‘first in the industry’ achievement possible.”
The ArcelorMittal Tailored Blanks facilities that contributed to this incredible milestone are: AMTB Detroit, AMTB Pioneer (Ohio), AMTB Woodstock (Ontario, Canada) and AMTB Concord (Ontario, Canada).

安赛乐米塔尔激光拼焊板是全球领先的汽车定制钢板或称激光拼焊钢板生产商。激光拼焊板经过冲压和组装制成汽车车身结构的关键部件，如门环、纵梁、立柱、前后门内板、前围挡板和车身结构侧围。
ArcelorMittal Tailored Blanks is the global leader in producing tailored steel blanks, or laser-welded blanks, for the automotive industry. Laser-welded blanks are stamped and assembled into critical components of a vehicle’s body structure such as door rings, as well as structural rails, door pillars, front and rear door inners, cowl sides and structural body sides.
激光拼焊门环是汽车安全笼的关键部件，能保护驾驶员和乘客，并取代了传统的多片点焊设计。将不同等级的先进钢材焊接成一个汽车零件提高了性能和安全性，支持轻量化目标，并降低了汽车制造商的总体生产成本。门环技术最新应用于2019款讴歌RDX和2019款RAM卡车上，还有例如本田Pilot、奥德赛和克莱斯勒Pacifica等路上的众多其他车辆。
A laser-welded door ring serves as a critical part of a vehicle’s safety cage, protecting both the driver and passengers, and replaces conventional multi-piece, spot-weld designs. The ability to weld together various grades of advanced steels into a single vehicle component improves both performance and safety, supports lightweighting goals and reduces overall production costs for the automaker. The door ring technology is most recently featured in the 2019 Acura RDX and 2019 RAM truck, as well as additional vehicles on the road today such as the Honda Pilot and Odyssey and the Chrysler Pacifica.
“量身定制”的生产流程通常从安赛乐米塔尔专利压力硬化钢Usibor®和Ductibor®开始，这两种钢材是用于热冲压的镀铝高强度钢。结合Usibor®和Ductibor®钢种能为汽车制造商提供几大重要的优势，包括减轻重量、改善碰撞性能、通过材料和制造优化节省成本。Usibor®和Ductibor®钢种在当地的数家落料厂完成落料，然后运往安赛乐米塔尔激光拼焊板底特律工厂，在那里进行激光消融。消融后钢材被焊接在一起，并运用多项质量控制工艺，以确保精度。随后，这些板料会被运往热冲压厂冲压制成汽车制造商要求的最终零件。
The “tailor made” process typically begins with ArcelorMittal’s patented press hardenable steels, Usibor® and Ductibor®, which are aluminium-coated high-strength steels used in hot stamping. The ability to combine Usibor® and Ductibor® offers several significant advantages to automakers including weight savings, improved crash behavior and cost savings through material and manufacturing optimization. The Usibor® and Ductibor® steel is blanked at one of several local blanking companies then shipped to ArcelorMittal Tailored Blanks Detroit where the enabling technology, called laser ablation, takes place. Once ablated, the steels are welded together, with multiple quality control processes being to ensure precision. The blanks are then sent to a hot stamper to be stamped into the final part required by the automaker.
