LASUS today offers a standardised wall thickness measuring system for all the forming stages in the hot production of tubes. The measuring principle is the proven ultrasonic technology which has now been further developed for use even at high temperatures by means of laser induction and detection. The measuring system and results from the practical application in seamless tube production are presented. LASUS supplies wall thickness measurement values with high local resolution and can be used even where a tool (mandrel bar) is used inside the tube. The variety of potential applications for the system and the excellent quality of the measurement data open up a new level of quality for seamless tube production.
