Laser Welding allows the assembly of a large number of materials, classic, hybrid and even the most reflective (copper, nickel, aluminium, steel, titanium, and alloys…) with important technical advantages compared to conventional technologies:

  • No filler metal ;
  • Sealing of welds ;
  • Retained electrical and magnetic properties;
  • High mechanical strength;
  • Excellent repeatability;
  • Very high welding rate;
  • Welding depth > 1 mm ;
  • All welding geometries: flat, circular, 3D, …

Many industrial customers trust our engineers and technicians to design and manufacture laser machines.
