LaserHybrid + Tandem

close
Laser Hybrid + Tandem welding is an automated high-performance welding process, in which the Laser Hybrid process is combined with the Tandem welding process. The combination of a laser beam with three arcs, opens up new dimensions in the joining of heavy gauge metallic sheet materials: high welding speeds with good gap bridgeability and good metallurgical characteristics.
The preliminary LaserHybrid process with one arc creates a very narrow heated zone with a great weld-depth to seam-width ratio. The following Tandem welding process has considerably less concentrated energy, and is characterised by a very high deposition rate. Steel sheets up to 8 mm thick can be welded with increased welding speed.
Base metals
Structural steels, ferritic/austenitic, duplex steels, aluminium materials
Fields of use
Plant and container construction, mechanical engineering and steel engineering, automobile and component supply industry, tracked vehicle manufacturing
