Saldatura. Studio delle tecniche e delle problematiche di saldatura

Applications of laser technology for polymer welding:

  • optimization of the process parameters using a thulium fiber laser source (in collaboration with IPG Photonics);
  • mechanical and structural characterization of welded joints.

Applications of Friction Stir Welding (FSW) technology:

  • optimization of welding parameters to weld both samples and production details;
  • mechanical and structural characterization of welded joints;
  • identification of the proper machine, tool and equipment design and process setup.

Applications of resistance welding technology:

  • optimization of parameters to perform welding between similar or dissimilar materials (according to ASTM / UNI);
  • mechanical and structural characterization of welded joints;
  • technical support for new industrial applications (in collaboration with TECNA SpA).

Applications of traditional welding technologies:

  • optimization of welding parameters;
  • mechanical and structural characterization of welded joints;
  • technical support for new industrial applications, regarding the materials to be welded, the filler materials and the identification of the most suitable shielding gas (in collaboration with LINCOLN ELECTRIC ITALY Srl and SIAD SpA);
  • optimization of welding parameters to realize small thickness joints, using a MIG-MAG robotic system (in collaboration with ROBOTECO Srl).
