SURFACE TEMPERATURE MONITORING DURING PULSED LASER, ELECTRON BEAM AND PLASMA ACTION
RESUMO
The set of pyrometers was developed for thermocycles monitoring in energy beams material processing. The combination of high speed (sampling time 20-50 μs), wide temperature range (800-4700 K) and spatial resolution (300-400 μm) provides the means for precise analysis of surface temperature dynamics. The advantages and the problems of pyrometry in pulsed laser applications are illustrated for Nd:YAG-laser action on metallic and ceramic materials. As a result, quantities such as the maximum value of temperature during whole thermocycle, the time of liquid phase existence, the duration of an allotropic transformation in a solid state, the heating and cooling rates, etc... may be determined. The real time monitoring of surface temperature is realised for electron beam welding and plasma cladding.
