Back to basics: The subtle science of burr-free laser cutting

Jan 25, 2017 · Caristan began by describing the basics: The laser beam’s intense energy brings the metal beyond its melting temperature, and the dynamic action of the assist gas evacuates the molten metal from the kerf. When using nitrogen, an inert gas, the cutting process relies solely on the beam’s energy to melt the metal.
