Laser welding on batteries
Laser welding batteries
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.
