Abstract :
Investigations of the melt removing in the gasjet-assisted CO2 laser cutting by pyrometer have been performed for steel plate 3, 6 mm and 10 mm thick are reported. The measurements of local brightness and brightness temperature were conducted for different values of cutting speed and assisted gas pressure.
