PowerPhotonic and the Warwick Manufacturing Group’s (WMG) joint paper on the effects of laser beam profiles on porosity in the laser welding of aluminium 1060, will be presented at ICALEO®, later this month. ICALEO®, the International Congress on Applications of Lasers and Electro-Optics, is the world’s premier platform for breakthrough, laser solutions. This year it will be held at the Palmer House® Hilton Hotel in Chicago, from 16th to 19th October.
PowerPhotonic, designer and manufacturer of freeform, wafer-scale optics, worked with WMG on the breakthrough research. WMG is part of the University of Warwick, focused on industrial, academic research collaborations. Dr. Stephen Kidd, Head of Sales and Marketing, at PowerPhotonic, said, “PowerPhotonic developed optimal beam shaping elements for aluminium welding, which WMG tested with its unique, welding simulation software. Results showed that freeform, optical beam profiles can reduce the likelihood of porosity formation in the welding of Aluminium 1060. These findings clearly show we can enhance efficiency in welding equipment with our beam shapers for aluminium, and probably other materials, too.”
Mark Wilson, Product Manager, and Alex Griffiths, Lead Development Engineer at PowerPhotonic, worked with Pasquale Franciosa, Senior Researcher and Qamar Hayat, Project Engineer, at WMG. The resulting paper, entitled, “Elucidating the Effect of Circular and Tailing Laser Beam Shapes on Keyhole Necking and Porosity Formation during Laser Beam Welding of Aluminium 1060 using a Multi-physics CFD Approach” will be presented by Qamar Hayatin the Welding of Aluminium session at ICALEO, on Wednesday, 18th October.
ICALEO®, alongside Laser Additive Manufacturing (LAM) and the International Laser Safety Conference (ILSC®), are conferences and exhibitions organised by the Laser Institute of America.
