Development of innovative welding systems for structural joints of Thermoplastic matrix-based Composites

Door surround structures (DSSs) are complex parts of an aircraft’s fuselage. To obtain highly integrated DSSs and be able to weld assembly clips on stiffened panels, the EU-funded DEWTECOMP project aims to develop an innovative and efficient induction welding system. The goal is for the system to achieve a structural bond between reinforcement parts (gussets, wedges, fittings) and structural frames. The design will include supporting tools, automated devices, heating systems, end effectors needed to weld DSS frames to DSS fittings and clamping methods to ensure contact between welding surfaces. The system will be based on CETMA - European Research Center for Technologies Design and Materials technology.
