Laser Ultrasonic Thickness Measurement

Lasus today offers a standardised wall thickness measuring system for all the forming stages in the hot production of tubes.

Laser ultrasonic thickness measurement.

The basic components of a laser ultrasonic system are a generation laser a detection laser and a detector. Hence if any corrections need to be made they can be made immediately. In some cases ultrasonics can measure diameter and ovality eccentricity. It is a non contact technique used to measure materials thickness detect flaws and carry out materials characterization.

Thickness measurement in 1 2 steel. In this application a laser ultrasonic system makes wall thickness measurements on tubes while they are in production. For measuring material thickness the process involves the following. Laserlinc uses ultrasonic frequencies from 2 25 mhz to 50 mhz.

In the laser ultrasonic testing system illustrated schematically here the small fiber coupled measurement head is placed near the part to be evaluated and the remote base station contains all the support equipment. Spacing of echoes gives thickness to high accuracy. Wall thickness measurement of seamless steel tubes has been the most successful application for laser ultrasonics. 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.
