Evaluation of liquid metal embrittlement crack in resistance spot welds under intensive welding condition using industrial X-ray computed tomography and machine learning

3D characterization of the propagation of liquid metal embrittlement inner cracks during tensile shear testing of resistance spot welds

“…As a non destructive technique, it allows for in situ testing of materials in a wide range of loading conditions (Buere et al [23]). Although a few works have initiated very recently the use of X-ray tomography to quantify the characteristics of LME cracks (Hang et al [24]), no study can be found in the literature regarding the use of this nondestructive technique to monitor the evolution of LME cracks in resistance spot welds and assess their impact on the weld fracture.…”
