Non-des­truc­ti­ve & cou­pling agent-free ultra­so­nic test­ing


Adhe­si­ve Bonds

Adhe­si­ve bonds are beco­ming incre­asing­ly com­mon in modern pro­duc­tion pro­ces­ses becau­se they offer num­e­rous advan­ta­ges. In the auto­mo­ti­ve indus­try, for exam­p­le, adhe­si­ve bonds make car bodies ligh­ter and increase their struc­tu­ral rigi­di­ty.

Howe­ver, the imple­men­ta­ti­on of good bon­dings is incre­asing­ly chal­len­ging. Becau­se they tend to leak and requi­re a clean, grease-free, dry and well-tem­pe­red envi­ron­ment, bond­ed joints should be tes­ted. Howe­ver, in prac­ti­ce the­re are only a few non-des­truc­ti­ve test­ing methods that are sui­ta­ble.  Air- cou­pled ultra­so­nic test­ing with the yoU­San sys­tem is a pro­ven method for this chall­enge.

Defect & Flaw Ana­ly­sis

The main advan­ta­ge of defect ana­ly­sis with air-cou­pled ultra­so­nic is the fast detec­tion of cracks, inclu­si­ons, pores and blow­ho­les in the pro­duc­tion line. Ultra­so­nics can detect and visua­li­se the chan­ge bet­ween air and mate­ri­al par­ti­cu­lar­ly well. This makes the various inspec­tion appli­ca­ti­ons in the field of defect ana­ly­sis easy to mana­ge for air-cou­pled ultra­so­nics.


Wel­ded, Bra­zed & Sold­e­red Joints

The sta­bi­li­ty of pla­s­tic welds , spot welds or sold­e­red joints can be ana­ly­sed regar­ding their qua­li­ty using air-cou­pled ultra­so­nics via two dif­fe­rent pro­ce­du­res we offer.

With ultra­so­nics, it is pos­si­ble to auto­ma­ti­cal­ly inspect the weld bead for cracks or holes. The uni­for­mi­ty of the waves, width and height of the weld bead can also be asses­sed. An inspec­tion for weld pene­tra­ti­on is also fea­si­ble. The eva­lua­ti­on of the­se para­me­ters is important for asses­sing the strength of the weld and stiff­ness of the enti­re com­po­nent.
