Sinterleghe will be the first company in the world to present technology that will enable aluminium welding at competitive costs.

Sinterleghe, within the 7th European Research & Development Framework for SMEs funded by the European Union, developed a new, completely automated adaptive control system called Smartdress. Besides improving production efficiency of welding lines and reducing downtime caused by poor electrode maintenance, Smartdress will also make it possible to weld aluminium sheets at competitive costs.

  • The revolutionary system was developed in collaboration with major international research institutes (Fraunhofer in Germany, TWI in the United Kingdom and VTT in Finland) as well as other 3 SMEs involved in the project. Smartdress, to be launched on the market at the end of 2017, comprises of 5 worldwide patents, two of which were developed specifically during the project and industrialised in bundle with the University of Trento.
