| Abstract Scope |
This study systematically analyses effective wear mechanisms at the shoulder and probe, separately for plunging and welding. The investigations were carried out with a robotic welding setup in which AA-6060 T66 sheets with a thickness of 8 mm were joined by varying weld seam lengths. To compare and differentiate the wear mechanisms between plunging and welding, repeated plunging cycles are initially investigated without tool travel. Subsequent experiments consider the welding as well whereby adhesion, abrasion, surface fatigue and corrosive wear were characterised for various weld seam lengths. During welding of the AA-6060 T66 sheets the tool material 1.2344 (X40CrMoV5-1) exhibited abrasive wear occurred due to self-damaging of the FSW tool. Furthermore it was found that tool wear was influenced by variations in the degree of hardness and tempering process. The wear analysis showed that no significant wear occurred during the plunging stage. |
