the statistical approach as an advanced method of quality management is widely
used. Here, a full factorial design 22 (two factors at two levels) with replicates
was
conducted to investigate the influence of the factors rotational speed (900
and
1200 rpm) and the welding speed (40 and 60 mm min-1) in the Friction Stir Lap
Welding (FSLW) process for the purpose of UTS-AS, UTS-RS, grain size-WZ,
grain size-HAZ and EPT. The study used plates of Al-alloys AA6061-T6. The
factors rotational speed and welding speed were significant and an increase
in the welding speed and a decrease in the rotational speed contributed to all
the
responses in FSLW. Effect of interaction was not significant for all responses
such
as UTS-AS, grain size-WZ, grain size-HAZ and EPT and the contribution of this
effect to the UTS-RS were positive, but less than 18%. The response surface
analysis and table of ANOVA indicate that the most effective level of factors
for
FSLW process in this study was achieved using a 900 rpm and 60 mm min-1
solution of rotational speed and a welding speed, respectively.]]>Liu, G., L.E. Murr, C.S. Niou, J.C. McClure and F.R. Vega,199737355361Mishra, R.S. and Z.Y. Ma,200550178Cederqvist, L. and A.P.
