Laser Welding Joins the Lightweighting Trend
Illustrative of the weight savings afforded by the combination of aluminum parts and laser welding, the Valley City, Ohio-based Shiloh Industries in 2014 unveiled the industry’s lightest, mass-produced aluminum door blanks, which consist of sheets of varying thickness and grade. Shiloh’s aluminum laser-welded door-inner blanks weighed 26.8 pounds, compared to 35.5 pounds for four aluminum, monolithic door-inner blanks of similar geometry. And while the aluminum laser welded door-inner blanks yielded a nearly nine-pound weight reduction per vehicle, the savings were even greater — 58 pounds — when compared to steel monolithic door blanks.
