Experimental Design and style With the two chosen feedrates of 1000 mmpm and 2000 mmpm, four temperature Together with the two selected feedrates of 1000 mmpm and 2000 mmpm, four temperature control set-points of 375, 400, 425, and 450 have been used for every feedrate, with an addicontrol set-points of 375, 400, 425, and 450 C had been employed for every single feedrate, with an more weld with no temperature handle (fixed rpm). For every single set feedrate/temperature tional weld with no temperature handle (fixed rpm). For each and every set ofof feedrate/temperature situations, one particular auto-tuning weld was performed, and then a single weld was run working with the conditions, one particular auto-tuning weld was performed, then a single weld was run utilizing the auto-tuned PID settings. Immediately after welding, the tool was allowed to cool to roughly auto-tuned PID settings. Just after welding, the tool was permitted to cool to approximately 30 C ahead of the subsequent tuning weld was performed. 30 before the next tuning weld was performed.two.7. Weld Setup two.7.
