WORKSHOP #2 | Fastening & Joining: New & Alternative Methods
Lasers for Lightweighting
Lasers are creating new possibilities to shape and join lightweight materials. In particular, lasers are being used to assemble aluminum doors, window frames, hoods, trunk lids and other parts that require a Class A finished surface. Lasers are advantageous in these applications because engineers can carefully control and focus the energy directed at the assembly. Joints produced by arc welding or resistance spot welding may require finish grinding; joints produced by laser welding need little or none. Another advantage of laser welding is its ability to produce continuous seam welds, parallel welds, and C- or S-shaped welds. That can make for stronger welds and allow engineers to use thinner materials in their designs. In this presentation, you’ll learn how automakers like Ford, GM and BMW are using lasers on their assembly lines.
