Abstract
The paper gives the results of fatigue tests carried out on raised edge joint assemblies obtained by laser welding. It examines joints made of FePO4 UNI 8092 steel sheets 0.8 and 1.2 mm thick, assessing the influence of the welding speed on the fatigue characteristics of the joints, for the same laser source.
The analysis of the data obtained for the various series of joints revealed in particular the contribution of the secondary bending caused by the geometry considered, and confirmed the possibility of applying the Uniform Scatter Band (USB) criterion also in this specific case.
