摘要

Process for controlling the quality of a welding seam, a sprayed layer, a thermal cut, a micro-cast part as testing composition during or after production comprises reflecting the radiation emission produced during the production process or an applied energy beam; processing using an IR camera operating in the spectral region of 600-2000 nm with a coupled computer; and displaying as an image or graphic. Preferred Features: The measuring is carried out during production or after production using a pulsed laser or a gas discharge. A silicon chip based on C-Mo is used as a sensor.
