Focus on labs & facilities
CO2 transverse flow laser
It is powered by a 6 kW source, equipped with 2.5 *5 m sized working table and is driven by a 5-axis programmable robot, which can treat flat and bended frames and components.
CO2 SLAB laser
Equipped with a 2.5 kW source, it reaches a significant gaussian-shaped beam (k30.8).
ND:YAG laser
The 4.4 kW diode pumped Nd:YAG laser couples good beam quality with the possibility to deliver it through optical fibres. It is installed on a 6-axis anthropomorphic robot, which allows us to program and actuate complex 3-D routes.
Friction stir welding
In this facility, metallic alloy welding occurs due to the heat produced by the high rotation speed of an element, which is pushed against the shoulders to be joined. This approach prevents materials from melting, as in fact the joint is obtained through the material plasticization and smearing.
As far as conventional welding equipment is concerned:
- The Gas Tungsten-Arc Welding (GTAW) and the PAW/GMAW apparatus are respectively fed by 450 A and 300 A inverter electric generators
- The Gas Metal-Arc Welding (GMAW) can be installed on the laser working table and controlled by a 6-axis robot
- Plasma-Arc Welding (PAW) and GTAW avail themselves of a 3 meter long working table.
