Tube-to-diffuser component for radiators
Industrial need
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.
IREPA LASER solution
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.
Technical challenge
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.
Results achieved
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.
