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.

In this application a laser ultrasonic system makes wall thickness measurements on tubes while they are in production. Laser ultrasonics uses lasers to generate and detect ultrasonic waves. The basic components of a laser ultrasonic system are a generation laser a detection laser and a detector. 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.

Hence if any corrections need to be made they can be made immediately. The laserlinc ultragauge series of ultrasonic devices measure wall thickness or layer thickness and concentricity of clear or opaque plastic rubber glass and metal products like tubing hose pipe insulated wire and cable. In some cases ultrasonics can measure diameter and ovality eccentricity. For measuring material thickness the process involves the following.

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. Laserlinc uses ultrasonic frequencies from 2 25 mhz to 50 mhz. It is a non contact technique used to measure materials thickness detect flaws and carry out materials characterization.
