Fiber Laser Welding Cuts Costs and Improves Results
Excelling arc welding and CO2 lasers at keyhole welding
Wolfram Rath has studied physics at Universities Heidelberg and Erlangen–Nuremberg with the degree of Dr.rer.nat. He was working with Siemens in CO2 laser and excimer laser development and applications before he became responsible for Coherent-Rofin's applications lab in Hamburg for macro applications. Since 2010 he is responsible for the Product Management for all high power laser sources.
Abstract
Lasers have been employed in a variety of welding applications for many years. And, as laser technology further develops and diversifies, its uses in welding continue to expand. This article provides an overview of high power lasers in keyhole welding. It then examines the characteristics and advantages of fiber laser sources for welding from Coherent-Rofin, in particular, and reviews a specific application that has benefitted from these lasers.
