Flexible and efficient generation of unique ship parts by an innovative laser-assisted additive production process.

Sub project:

Gall & Seitz Systems GmbH – Development of a demonstrator plant for laser assisted cladding utilizing a non-transfered electrical arc.


The automated creation and reconditioning of metallic structures through additive manufacturing methods represent the state of the art in the industry. Gall & Seitz Systems GmbH (GSSY), for example, uses Laser-Powder-Cladding for the preparation of ship components such as pistons, crankshafts or rudder shafts. GSSY aims to apply this wire-based process for manufacturing processes. Because of the comparatively high achievable cladding rates, this type of process is an addition to Laser-Powder-Cladding.

The new process is based on a pair of electrodes with a non-transferred arc for efficient melting of the wire filler material. When the melt droplets produced in this way hit the component surface, a laser beam is used to influence the further flow of the melt. In the project extensive experimental investigations to determine the appropriate process parameters will be performed.

The smart system technology, which will be developed within the project, will be implemented in a robot-supported demonstration system. Besides the project coordination, GSSY takes over the development of the demonstration system, its construction and commissioning at project partner Meyer Werft.
