Tube-to-diffuser component for radiators

Ensuring an efficient thermally conductive bond between a tube and a radiator diffuser without perforating the tube, in order to guarantee optimum heat transfer in consumer goods applications.

Development of a laser welding process with fine optimisation of path parameters and energy input. Design of suitable tooling to secure the operation and its repeatability.

Creating an efficient thermally conductive joint between a tube and a radiator diffuser without perforating the tube, to ensure optimum heat transfer. Precise control of laser penetration is critical to achieve a strong joint without weakening the tube structure.

The solution makes it possible to replace a brazed joint with a welded joint, offering high and reproducible joint quality. It also improves process productivity thanks to shorter cycle times and delivers significant energy savings in manufacturing.
