Summary

This panel discussion, moderated by Mark Elliot, brings together three experts in laser safety and welding: David Lawton (Kentek), Rex Alexandre (Handheld Laser Institute), and David Werba (Miller Electric). The conversation centers on the safety challenges and knowledge gaps associated with the increasing use of handheld laser welding systems in industrial settings. Key topics include common misconceptions about laser hazards, the unique risks of class 4 lasers, the lack of adequate training and information for traditional welders transitioning to laser technology, and the regulatory landscape in Europe and the US. The experts emphasize that handheld lasers are inherently class 4 and cannot be fully enclosed, making training and risk assessment crucial. They discuss the need for simplified, accessible safety information and the shared responsibility of manufacturers, distributors, regulators, and end users. Specific resources mentioned include AWS Safety and Health Fact Sheet No. 46 and an IIW white paper on handheld laser welding. The discussion also touches on the role of laser safety officers, the importance of proper PPE, and the need for a cultural shift in safety practices.
