Non-des­truc­tively detect cracks, inclu­si­ons or pores wit­hout the need of cou­pling agents

How does a defect ana­ly­sis with air-cou­pled ultra­so­nics work?

The sound is reflec­ted or scat­te­red by defects or other inho­mo­genei­ties within an test object. This chan­ge in the sonic waves makes a defect in the com­po­nent detec­ta­ble. This is why ultra­so­nics is used for crack detec­tion, for exam­p­le.

What can be seen when test­ing mate­ri­als with ultra­so­nics?

Para­me­ters rela­ting to the num­ber, size, shape or posi­ti­on of defects can be deter­mi­ned during a defect ana­ly­sis with air-cou­pled ultra­so­nics. With the­se, the com­pon­ents to be exami­ned can be easi­ly clas­si­fied accor­ding to OK and NOK parts (rejects).

What are the Advan­ta­ges of Mate­ri­al Test­ing with Ultra­so­nics?

The pro­cess is fast, relia­ble and cost-effi­ci­ent and is par­ti­cu­lar­ly sui­ta­ble for use in manu­fac­tu­ring com­pa­nies whe­re a quick check is requi­red. It is also non-inva­si­ve, which means that it does not dama­ge or affect the mate­ri­als. In addi­ti­on to defect and flaw ana­ly­sis, air-cou­pled ultra­so­nics can be used to inspect adhe­si­ve bonds or welds.

Over­all, mate­ri­al test­ing with ultra­so­nics is a valuable way of che­cking the inte­gri­ty of mate­ri­als and can help to iden­ti­fy and rec­ti­fy qua­li­ty pro­blems at an ear­ly stage.
