Through partnership with CETMA and SYNERGO from Italy we worked together in the maturation of Induction Welding as a joining technique for thermoplastic composite parts. The technology outstands as one of the more consistent for joining parts taking advantages of thermoplastic resins properties, thus avoiding the use of rivets or other mechanical joints. Now after research projects, for example, like welding a keel beam aircraft structure, welding rotorcraft structural parts or welding door frames aircraft structures, we are ready to offer you a comprehensive package so you can do your own way, discover the power of use induction welding, in terms of automation, cost effectiveness, weight reduction and strength results. Whether you need to develop from scrap or start a serial production qualification, we can provide a solution for you. We adapt to be you partner all the way form application development to supply of the hardware systems full of data processing for your data science implementation toward continuous improvement. This approach will be extremely useful for you to implement Digitization and Digitalization in your company.

Induction Welding

The Technology:
 Induction Welding for joining composite parts

Sectors: Aeronautic, Space, Automotive, Naval, Wind Energy, Hydrogen Systems, ...

It uses inductive heating for melting down polymer matrix in the joining zone. The components to be welded are submitted to an alternating electromagnetic field with a frequency around five hundred KHz. When there are electrically conductive loops in the component, e.g., due to carbon fiber reinforcement, eddy currents are induced, resulting in efficient, localized heating of the laminate.

When the part is made with glass fiber reinforcements which are electrically non-conductive, extrinsic electromagnetic susceptors, e.g. metal grids, must be incorporated to the composite array to convert the magnetic energy into thermal energy.                

In the case of ferromagnetic materials, hysteresis effects contribute further to heating. The heating is based on two mechanisms, namely, the energy dissipation due to Joule heating and energy dissipation due to magnetic hysteresis. The heat generation is described by the equation Q = I * I * R * t => Q = Heat; I = Current; R = Resistance; t = time.


  • Fast and clean process.

  • Can be applied to complex geometries with irregular contoured surfaces.

  • Weld can be re-opened by induction re-heating which makes it possible to open an assembly for internal repair, part replacement, and repair defective welds. 

  • With right parameters it delivers high values of G1c and SLS values

    • Joining of several materials, as carbon fiber composites and aluminum​

Systems allow allows to get extremely high mechanical properties of the joint, without drawbacks typical of other welding techniques (no need of metallic mesh between parts to be welded).​

Pieces can be reworked or repaired; no special environment is required to operate. Immediate equipment turns on - turn off and exceptionally low power comsumption.

Machines are result of our research for an innovative process and a new generation of equipment for welding of composites. They are designed based on computer Electrophysics simulations FEM, laboratory test and measurement of mechanical proprieties of welded parts, noting high values of mechanical and fatigue resistance.
