Laser hybrid welding

Laser hybrid welding is a process combination of the MAG/MIG process and CO2 laser beam welding. This plant-integrated technology combines the advantages of both welding processes and enables large welding depths at high welding speeds, resulting in low thermal stress on the base material. The process is used in particular for the production of laser-welded profiles.

Double Laser Hybrid Process (DLHP®)

The Double Laser Hybrid Process (DLHP®) combines simultaneous laser/MAG welding with a special inductive heat treatment of the steel. This demonstrably reduces the risks of cracking and fracture under load in the weld area. The process developed and patented by Stahlkontor is suitable for the safe, faster and more economical production of parts and components for armored vehicles of all types, rail vehicles, door systems and facade elements made of high-strength steels. Comparative impact and sprue tests have already been successfully completed at Wehrtechnische Dienstelle 91.
