In materials processing heat input into parts is a major issue. To reduce heat impact, temperatures can be evaluated to optimize processes i.e. for low distortion, low dilution or small heat affected zones. For the first time a new sensor which combines ratio pyrometry with 2D-resolved measurement is applied for laser processing. The advantages of independence of emissivity and attenuation of the thermal radiation together with 2D-temperature information are demonstrated on laser cladding. The temperature distribution at the parts’ surfaces becomes available with quantitatively high precision. This information was successfully applied to validate FEM-based temperature field simulations.
