The influence of two different weld imperfections (gap/crack) on the fatigue behaviour of spot welded joints was tested
Surface cracks have no influence on the fatigue life
Samples with cracks in the electrode indentation /HAZ where tested
Stiffness curves are not significantly influenced by surface cracks
3D FE-Simulation demonstrate no changes of stress due to surface imperfections
•
Welding under external forces was found suitable for characterizing AHSS materials
New quick and easy-to-perform procedure for establishing a material ranking regarding cracking susceptibility
