processes - Maximum metallurgical
integrity - Efficiency, quality
and reliability
Welding technologies
We select the most suitable joining process for each application, based on material, geometry, tolerances, required strength and production volume.
Laser Beam Welding (LBW)High-precision laser welding
Laser welding uses a high-energy beam to melt and join materials at the contact zone without adding extra material.
The concentration of the beam’s energy allows work with very small heat-affected zones, resulting in joints with high metallurgical integrity, minimal distortion and an excellent dimensional finish.
Key advantages
- Complex and rotational geometries
- Tight assembly tolerances
- Heat-sensitive materials
- Series production where repeatability and speed are critical
Laser Metal Deposition (LMD)Laser-based metal additive manufacturing
The LMD process deposits metal powder directly onto the surface using a high-precision laser, creating a complete metallurgical bond with the base material.
Main applications
Joining
Enables strength and/or sealing joints in assemblies with wide fit tolerances, bridging gaps of up to 1 mm.
Coatings
Deposition of high-performance material to improve resistance to wear, corrosion or severe tribological conditions.
Rebuilding
Dimensional recovery of worn parts or adaptation to new specifications without the need to manufacture a new part.
Digitalisation technologies
We capture, analyse and transform the reality of your components into accurate data to improve control, quality and product development.
3D scanning
High-precision capture of part and assembly geometries, directly on the shop floor and in process, with no need for disassembly.
3D inspection
Full analysis of mesh deviations and dimensional and geometric errors against the CAD model and drawing, with customised reports according to the standard and customer specifications.
Reverse engineering
Conversion of the scan into optimised CAD models for redesign, additive manufacturing and product development.
