Résumé : |
Induction welding in a highly efficient and flexible joining process that uses an electromagnetic field for heating the component. An inductor moves above the surface providing a contact-free heat input limited to the bonding zone. Afterwards, the weld is consolidated under pressure. The component can be utilized immediately as no curing time is necessary.
Up to now, this technology was limited to flat geometries. In the framework of an industrial cooperative research, the process was enhanced to 3D geometries for joining of complex shaped components. A newly development welding unit integrating the heating and consolidation fonction is handled by a six-axis industrial robot allowing cured 3D seam design. This setup was used for welding single lap joints of GF/PA6 that were characterized by mechanical and microscopical analyses. The main parameters force, generator power, and feed were investigated and their influence on the mechanical properties in shown. A comparison between GF/PA6 with local welding filler and CF/PA6 without welding filler is drawn. In case of CF/PA6 the woven fibers are directly heated by the induced magnetic field. |
