Laser Materials Macroprocessing

The Laser Materials Macroprocessing (MACRO) track comprises some of the most productive laser processing applications. Although these applications have been broadly adopted, researchers and industry are persistently innovating to provide new techniques and novel technologies to advance macro materials processing. While welding currently dominates its industrial applications, this track welcomes contributions on experimental work and modelling across all manufacturing processes based on cw-lasers, e.g. cutting, surface and heat treatment as well as welding. The track involves contributions on emerging key trends like beam shaping, artificial intelligence, high power laser sources, as well as monitoring and control technologies.
