In order to ascertain a seamless supversvision of all processes, an evaluation of which parameters need to be continually supervised is necessary. During this evaluation, it is investigated which factors are relevant for a concrete application, while the concrete test process is chosen in the production stage.
Quality assurance of the welding process is performed through measurements during and after welding. Among them are tests of the optical attributes prior to welding as well as measurements of laser output, welding time, elasticity and other dimensions during welding. Downstream the welding, tests using ultrasonic and x-rays as well as computer tomography allow conclusions on the quality of the weld.
