Replication Data for: Analytical Description of the Criterion for the Columnar-To-Equiaxed Transition During Laser Beam Welding of Aluminum Alloys

The here published experimental data was done in a collaborative DFG project between IFSW and MPA (project number 398552773). The published data is repilcation data for a publication. In this project laser beam weld trials were conducted and the resulting weld seams were prepared metallographically. The here presented data is a set of optical micrographs etched with Barker's method. The optical micrographs highlight the type of weld microstrucutre: columnar dendritic and equiaxed dendritic grain structure.
