We study the application of laser technology in the welding, hardening and texturing of aluminium and titanium alloys.

For the last 10 years, the group has been working on a line of research into the laser treatment of light alloys (aluminium and titanium), carrying out studies on the optimisation of welding processes and the re-melting of these alloys.
The microstructure, mechanical properties and corrosion resistance of the laser processed samples have been analyzed. Several scientific papers have been published.

Línea de investigación 01

Laser processing of metallic materials.

For the development of this line of research the group has two laser equipments:

  • Procesado láser de materiales metálicos
  • Procesado láser de materiales metálicos
The first of these is a ROFIN-SINAR diode laser model DL028S with a maximum power of 2.8 kW.

The main characteristic of this equipment is the size of the spot, which depending on the lens used can be up to 4.02mm2. This makes it especially useful in surface processing applications.


  • Conduction welding of aluminium and titanium alloys.
  • Surface hardening of different metal alloys.
The second laser used in this line is a pulsed fiber laser (ytterbium-doped fibber laser) RofinEasymarkF20 with a maximum power of 20 W.


  • Texturing of Al.
  • Marked.
  • Selective paint removal.
  • Removal of titanium mould release agent.
  • Modification of hydrophobic properties.
  • Modification of hydrophobic properties.


These are some of the publications of the members of the Protection and Corrosion Group related to this line of research.
