SIRIO Antenne

For the production of SKALA antennas for the SKA-Low radio telescope in Australia, SIRIO Antenne operates a dedicated laser welding system engineered for outstanding quality and repeatability. The system features a 2 kW laser source and a welding head on a CNC Cartesian gantry for high-precision XYZ motion and total process consistency. A dual lathe on a rotating wall allows loading and unloading while welding is performed inside the cell, minimizing downtime and maximizing efficiency. Laser welding is ideal for aluminum, offering high speed, precision and low heat input. However, it demands tight dimensional tolerances. This is where SIRIO Antenne’s expertise makes the difference, with advanced production processes and quality systems developed to deliver fully compliant components.

Tecnelab featured the collaboration between Sirio Antenne and Opto Engineering within the international Square Kilometre Array Observatory project, the world’s largest radio telescope. For the SKA-Low site in Australia, Sirio Antenne is manufacturing 78,520 low-frequency antennas designed to detect the oldest signals in the Universe. A project of this scale requires uncompromising quality standards. That is why we implemented an advanced quality control system based on Opto Engineering machine vision technologies, enabling 100% dimensional inspection of every antenna. Software, lenses, cameras and illuminators work together to ensure precision, reliability and production efficiency on a large scale. A technological and industrial challenge that demonstrates how innovation, manufacturing expertise and collaboration can bring Italian know-how to the forefront of international scientific research.
