Experimental investigation on aluminum alloy 6061 friction stir welding with varying tool pin profiles

For lightweight, high-strength-to-weight ratio constructions, Al alloy 6061 is a popular choice in manufacturing. It is a new method of combining materials that doesn’t need melting or casting, but instead uses friction stir welding. Frictional he at is created whenever two surfaces come into contact. The quality of the weld is influenced by the welding tool’s pin profile. In this study, the effect of welding speed and tool pin shape on FSP zones in 6061 and 6082 Al is examined. This is an experimental study. The profiles of the tool pins are utilized to examine welding joints. Triangular and square profiles are also included in the list of possible shapes. Cutting tools were compared to welding plates in this investigation. A milling machine with a fixtur e, cutting tools, and plates was used for all practical experiments. This technique makes use of spindle revolutions per minute (rpm) and cutting feed.
