Laser beam-submerged arc hybrid welding: New process for joining thick duplex steels

Laserstrahl-Unterpulver-Hybridschweißen: Neues Verfahren zum Fügen von Duplexstählen
09 November 2022

With laser beam-submerged arc hybrid welding, the Laser Zentrum Hannover e. V. (LZH) and the Fraunhofer Institute for Machine Tools and Forming Technology IWU have succeeded in joining duplex steel in sheet thicknesses of up to 30 mm quickly and reliably. 

The novel process developed by the researchers as part of the DupLUH project on behalf of the Research Association for Steel Application (FOSTA) combines the advantages of established submerged arc welding with the high productivity of a beam welding process. The results could pave the way for laser beam-submerged arc hybrid welding in the industrial welding production of thick duplex steels.
