Laser Optics Guideline for Welding - Advantages and Differences of Scanner and Fixed Beam Optics
Laser welding is well established in the manufacturing world of sheet metal, automotive and electronics. However, the right selection of laser power source, optics and process parameter is complex and depends on the specific application. This presentation focuses on differences between fixed beam optics and 2D/3D scanner optics. Best practices on real world applications will be shown to highlight and explain individual advantages in processing speed, shielding gas supply and resources. Advanced techniques like beam oscillation and the importance of the right spot sizing are demonstrated to show how to overcome gap conditions and bad part fit ups.

Laser Welding with Beam Wobbling and Power Modulation to Improve Weld Quality of Aluminum Alloys for Manufacturing of E-mobility Parts
The ALO4-O processing head combines the advantages of tactile seam tracking with the laser beam wobbling of the remote optics. Latest developments have shown stabilizing effects of the molten pool, increased processing speed, possibility to tailor the shape of the weld seam and superior joint quality in those applications with 6xxx series aluminum alloys which, traditionally, are prone to critical defects such as blow-out and cracks. Application cases from WMG, at the University of Warwick, and the Scansonic application lab in Berlin will demonstrate the capability of the ALO4-O in terms of joint strength, reduction of weld defects and increase of process stability in applications targeting aluminum-intense structures for e-mobility. Case studies will be drawn from manufacturing of battery enclosures which requires structural joints between dissimilar aluminum (casting, extrusion, sheets) as well as fully sealed joints to comply with OEM requirements.
