A theoretical model for the calculation of the reflections on an arbitrary position above the process zone, as well as a radiation analyzer based on a modular set-up are presented. This device enables a time- and space-resolved measurement of the reflected radiation. Using the experimental results, characteristic positions on the hemisphere could be identified to calibrate the theoretical model. The calibrated model allows to analyze the reflected radiation during the welding process to determine the energy which is absorbed by the work piece.
