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

The DEWTECOMP project proposal objective is to develop an induction welding system to achieve innovative and efficient way of structural bond of reinforcement parts (gussets, wedges, fittings) to structural frames to obtain a highly integrated Door Surround Structure (DSS), as well as to be able to weld assembly clips on stiffened panel. In order to achieve the main foreseen objective and system characteristics DEWTECOMP project will:

• Provide at the beginning of the project a comparison of the state-of-the-art welding technologies (i.e. Laser, Induction, Conduction, Resistance and Ultrasonic welding-but not limited to them) with a benchmark of maturity to justify the use of Induction welding CETMA patented technology vs baseline resistance welding.
• Propose and manufacture the most suitable and innovative system design for the induction welding technology to be applied for DSS, including supporting tools, automated devices, heating systems, end effectors required to weld DSS frames to DSS fittings and clamping methods to ensure welding surfaces contact. The induction welding system will be based on CETMA patented technology.
• Generate process parameters in such a way that delivers the relevant information to Topic Manager but keeps the industrial secret that will be part of the exploitation plan of the consortia. For instance, welding parameters (temperatures, speeds, pressures, tolerances…) as well as the tooling list and materials required will be provided to Topic Manager.
• Manufacture and test coupons to validate the equipment and tooling.
• Delivery of the Prototype System and tooling set for manufacturing to the Topic Manager facilities.
• Carry on different manufacturing trials in order to proof the welding system characteristics

Support set up in the Topic Manager premises.

Follow up of the works performed by the Topic Manager until the end of the manufacture of a demonstrator compliant with typical aeronauticals.
