To ensure a constant quality of manufactured components and to shorten the development process between CAD model and suitable produced components a quality management system is inevitable. Therefore, a system has been developed to evaluate the cladding process by means of thermographic measurements. Melt pool temperature measurements by a thermal imaging camera has been processed to 2- and 3-dimensional temperature maps of the manufactured component, like a tomographic image, to easily reveal weak spots in the process and the component itself. The quality management system was tested and evaluated on several laser-cladding processes with various failures.}, language = {en} }
