This paper presents a new welding quality evaluation approach depending on the analysis
by the fuzzy logic and controlling the process capability of the friction stir welding of
pipes (FSWoP). This technique has been applied in an experimental work developed by
alternating the FSW of pipes process major parameters: rotation speed, pipe wall thickness
and travel speed. variable samples were friction stir welded of pipes using from 485 to 1800
rpm, 4–10 mm/min and 2–4 mm for the rotation speed, the travel speed, and the pipe wall
thickness respectively. DMAIC methodology (Defining, Measuring, Analyzing, Improving,
Control) has been used as an approach to analyze the FSW of pipes, it depends on the
attachment potency and technical commonplace demand of the FSW of pipes process.
The analysis controlled the Al 6061 friction stir welded joints’ tensile strength. To obtain
the best tensile strength, the study determined the optimum values for the parameters from
the corresponding range. |
