Customized welding

Conventional, innovative and exclusive technologies


Conventional welding technology 

  • MAG/MIG and WIG welding processes (for applications in the sector of high-strength fine grain structural steel, structural steel, stainless steel and aluminum)
  • Orbital MAG/MIG processes
  • Stud welding with capacitor discharge and drawn arc ignition


CO2 Laser beam welding

  • Profile welding up to lengths of 12 m
  • Butt welding (linear) of oversized blanks
  • Butt welding (linear/non-linear) of tailored welded blanks (TWB)
  • Construction welding with laser beam (two-dimensional / spatial)


Laser-hybrid welding

Laser-hybrid welding is a combination of processes consisting of MAG/MIG welding and CO2 laser beam welding. This system-integrated technology combines the advantages of both welding processes to allow large penetration depths at high welding speeds with the benefit of a low thermal load on the base material. The process is used in particular for the production of laser-welded profiles.


Dual LaserHybrid Process (DLHP®)

With the Dual LaserHybrid Process (DLHP®), simultaneous laser/MAG welding is combined with a special inductive thermal treatment of the steel. This is proven to reduce the risk of stress-induced cracking and breakage in the welding zone. Developed and patented by Stahlkontor, the system is suitable for a reliable, faster and more economical production of parts and components for armored vehicles of all types, rail vehicles, door systems and façade elements made of high-strength steel. Comparative ballistic and explosive tests have already been carried out successfully at the Bundeswehr Technical Centre 91.
