Ana­ly­ze welds and sold­e­rings non-des­truc­tively & wit­hout cou­pling agents

Pla­s­tic Welds — many advan­ta­ges, but also high stan­dards

Poly­mers do not rust or cor­ro­de, bring enorm­ous weight savings and make it pos­si­ble to easi­ly pro­du­ce com­plex parts, which makes them ide­al for cars and air­crafts.

Howe­ver, high pro­duc­tion speeds can push pro­ces­ses such as laser wel­ding to their limits. The­r­e­fo­re, it should always be che­cked whe­ther the strength of the pla­s­tic weld meets the requi­re­ments. This is the only way to ensu­re that they can with­stand the high stres­ses in the auto­mo­ti­ve and aero­space indus­tries at all times. Weld seam test­ing with ultra­so­nics is ide­al for this pur­po­se.

This is how a Cou­pling gent-free ultra­so­nic inspec­tion of a weld seam works

The inspec­tion pro­ce­du­re for pla­s­tic welds is simi­lar to the pro­ce­du­re for defect ana­ly­sis: Are­as with defects dif­fer in the ultra­so­nic image com­pared to defect-free are­as. This method also uses air pockets or inter­nal sepa­ra­ting lay­ers to atte­nua­te the trans­mit­ted ultra­so­nics. The­re are two pos­si­ble pro­ce­du­res for this method:

1: Trans­mit­ter and recei­ver are loca­ted on the left and right side of the weld seam.
In this case, the weld seam is soni­ca­ted. As with gene­ral defect ana­ly­sis, inclu­si­ons can be detec­ted.

2: Trans­mit­ter and recei­ver are loca­ted abo­ve and below the weld seam.
The sound is con­duc­ted over the sur­face through the weld seam and picked up again on the other side. Thus, in addi­ti­on to the first vari­ant, con­clu­si­ons can also be drawn about the qua­li­ty of the bond.
