In a recently finished project at University West, SAMw (Synergy for Additive Manufacturing using laser beam heat source and wire), the L-DEDw process was developed for manufacturing of duplex stainless steel and a high-end component for an Alfa Laval application was successfully manufactured. In addition, this component was then placed in and tested with success in its real application, i.e. reaching TRL 5/6 on a component maturity level.

In this project SESAM selected technical parts of the L-DEDw process will be further developed, with system expert support from Procada and Adaxis. The welding wire that will be used in the project is supplied by voestalpine Böhler Welding, that have identified this area as a potential business area for increased sails opportunities of welding wire. Furthermore, the application area for the L-DEDw process will be expanded in this project to also include manufacturing of other component geometries of interest for Alfa Laval’s applications. The work in this project will be conducted in a former production cell at Production Technology Centre (PTC) in Trollhättan. Here staff from Alfa Laval will also take part of the process development and investigate the material quality, which thereby assures the necessary competence development within the company for successful upscaling and implementation of the L-DEDw process for production.
