Description
Currently, thick-walled steels are mostly joined using arc-based welding processes in the industry. The industrial use of alternative welding processes, such as the laser-gma hybrid welding process, are limited due to some process-specific challenges, such as the gravity-induced droplet formation at the weld root, limited gap bridgeability and a high sensitivity to manufacturing tolerances, or poor mechanical properties due to high cooling rates.
In this work, laser-gma hybrid welding with contactless electromagnet backing is presented. With this innovative process, it was possible to join plates with a thickness up to 30 mm using a 20-kW fiber laser. In addition, the gap bridgeability could be significantly increased. The mechanical properties such as the tensile strength and Charpy impact strength could also be increased. With the implementation of this process in industry, e.g. in shipbuilding or wind tower fabrication, the productivity can be significantly increased compared to the arc-based welding processes, such as the submerged arc welding.
