As the European market leader for laser-welded absorbers,
KBB Kollektorbau offers top quality features:
- Fully automatic CNC-controlled welding plant
- Ultra-precise focussing of the laser beam for increased output
- 100% fully automatic pressure test in a closed cabin
- Automatic production data collection, enabling the traceability of products
- With around 25,000 welding spots per absorber, the strength and durability of the weld has been proven through accelerated ageing tests
A pulsed laser melts small sections of the pipe and plating, fusing the melted particles. The targeted and precisely-metered laser beam only heats the absorber at the welding spot, allowing the heat-affected zone to be kept to a minimum. This keeps material stress to a minimum. In this manner, per meter of pipe, up to approximately 1,000 welding spots assure a durable and stable connection and excellent heat transfer characteristics.
