Notes:
This work summarizes the outcome of recent research by the authors on modeling theformation of seam welds in aluminum extrusion and on evaluating the related mechanical propertieson the final products. A profile with a seam weld in the middle section was produced with differentdie designs in order to investigate the relation between die design and local welding parameters,such as contact pressure, temperature, time of contact, strain and strain rate paths. The local weldingconditions were evaluated by complete thermo-mechanical 3D FEM simulation of the processes.Specimens were extracted from the profiles and tensile tested, the resulting mechanical propertiesbeing discussed with respect to the local welding conditions. The possibility to adopt criteria forassessing the welding quality is discussed, together with the effect of high speed damage cracking
