Laser Welding Joins the Lightweighting Trend

Industrial Photonics

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.
