Summary: This paper presents the results of bead-to-plate welds performed with different aluminum cored wires in comparison to solid wire welds. The droplet transfer is recorded with a high speed camera and the electrical signals are measured simultaneously. Cross sections of the welded samples with cored wires show improved weld bead geometry and less tendency of porosity.
