Ultrasonic testing

Ultrasonic testing is one of the methods of assessing technical conditions of a device and its elements. Our fully equipped lab and qualified staff whose skills are confirmed by Level 2 PN-EN 473:2002 certificates allow us to respond timely to the fast-growing demand of our customers.

Cast, weld and forging tests

Ultrasonic defectoscopy is one of the non-destructive testing methods that ensures safe operation of industrial installations. Tests are carried out  according to ultrasonic testing norms (PN-EN 583, PN-EN 1712, PN-EN 1713, PN-EN 1714, PN-EN 10228, PN-EN 12680) and the internal procedure of our Materials Research Lab.

Wall thickness spot measurements

Ultrasonic thickness measurement is a popular technique of assessing the technical conditions of a device. Measurements are taken in accordance with PN-EN 14127 norm.

Tests results visualisation through thickness maps, corrosion cavities and delamination

A special software for test results analysis and illustration devised by MEGroup specialists, as well as the use of automatised measurement system allow for a graphical illustration of test results in the form of thickness maps (including the possibility of examining composite laminates by means of submersion tests), corrosion cavities and lamination.

Tests of acoustic properties of the material

The changes in the micro-structure of material caused by the outside and technological factors can be assessed with the ultrasonic method. Setting up the damping ratio and the speed quotient of vertical and horizontal waves allows to set up a material constant for components exploited. A comparative analysis of results obtained with the values of a material prior to its operation is one of the factors taken into account in assessing the condition of material exploited.

Ultrasonic submersion tests

Ultrasonic submersion test is a method used for defect detection in thin laminates and composites. This method is characterised by high sensitivity to damping changes of an ultrasonic wave in a material and thus reacts on all inadequacies of the structure. Ultrasonic submersion tests are used jointly with a computerised image analysis and allows for generating maps of materials examined together with the location of inner defects.
