Identifying and studying the impact of significant process parameters on friction stir spot welding of the al6061 alloy using doe

الملخص EN

Friction Stir Spot Welding (FSSW) is a solid-state multi-parameter welding process that is widely used especially in the automotive industry.

This paper examines the manner in which its four primary parameters (tool rotational speed, pin length, shoulder width, and dwell time) can be employed to produce stronger welds for Al6061 alloys.

A Taguchi Statistical Analysis system was utilized to minimize the number of experiments, costs, time and energy required for the parameters.

Significant valid statistical results were obtained which suggested that tool rotational speed and pin length are the most significant factors for determining welded joints strength.

Optimum parameter settings for FSSW Al6061 alloys within the factors were also investigated and the corresponding levels required to achieve high strength welds were identified.
