20.500.12556/RUL-148507 Kontrola razpok pri avtomatiziranem varjenju nosilca kolesa iz visoko trdnostnega jekla Crack control at automated welding of a trailing arm from high strength steel V magistrski nalogi smo obravnavali kontrolo razpok na preoblikovancih iz visoko trdnostnega jekla po fazi varjenja nosilca kolesa. Visoko trdnostna jekla so zaradi zahtevnih materialnih lastnosti med preoblikovanjem podvržena velikim obremenitvam, kjer lahko nastale zaostale napetosti privedejo do pojava inicialnih razpok na končnem izdelku. Za kontrolo razpok smo uporabili obstoječ kontrolni sistem na principu robotskega 3D laserskega skeniranja površine, ki se primarno uporablja za preverjanje zvarnih spojev. V magistrskem delu smo na preoblikovancih definirali potencialna kritična območja nastanka razpok in na podlagi tega zasnovali preizkuševališče, ki omogoča zajem 3D slik. Z rezultati zajetih meritev smo dokazali, da lahko z obstoječim kontrolnim sistemom zanesljivo zaznavamo razpoke do velikosti 1,5 x 0,5 mm. In our master's thesis, we addressed the control of cracks in post-welded transformations of high-strength steel in the wheel carrier assembly. Due to demanding material properties, high-strength steels are subjected to significant stresses during forming, where resulting residual stresses can lead to the occurrence of initial cracks in the final product. For crack control, we utilized an existing inspection system based on robotic 3D laser surface scanning, primarily employed for weld joint verification. In the master's work, we identified potential critical crack initiation areas on the formed components and based on this, designed a test setup enabling the capture of 3D images. Through the results of the captured measurements, we demonstrated that with the existing inspection system, we can reliably detect cracks down to a size of 1.5 x 0.5 mm. visoko trdnostno jeklo razpoke pri preoblikovanju pločevine kontrola kakovosti laserska triangulacija obdelava 3D slik high strength steel cracks at sheet metal forming quality control laser triangulation 3D image processing true false false [D.
