At the X-ray facility at the IFSW, so far it has been possible to record videos with a framerate of 1 kHz to 3 kHz. In this setup the X-rays propagate through the workpiece and are filmed by the high-speed camera via a projection on the scintilator. Through a new sample formation and using less attenuating sample material, frame rates of 10 kHz could now be achieved during high-speed laser beam welding processes. This allows the laser beam welding process to be recorded in a highly dynamic manner, which means that a more precise temporal resolution of the process can be measured. The temporal resolution in the case of this 10 kHz x-ray video is 0.1 ms. With the X-ray system at IFSW, high-speed laser material processing can be recorded with a high temporal resolution up to 10 kHz in order to detect effects during the process.
