The FSW process parameters such as tool
rotational speed, travel speed, material thickness, play a
major role in deciding the weld quality. The aim of this work
was to investigate the mechanical properties in order to
demonstrate the feasibility of friction stir welding for joining
Al 6061 aluminum alloy welding was performed on pipe with
different thickness (2 to 4)mm, six rotational speeds (485
to1800) RPM and a traverse speed (4 to 10)mm/min was
applied. Response surface methodology was used to predict
the Tensile strengths, the percentage of elongation and
hardness of friction stir welded 6061 aluminum pipe are
compared with measured values. The effect of FSW process
parameter on mechanical properties of 6061 aluminum pipe
has been analyzed in detail. The result acquired through
model suggestion (RSM) has been proved to be successful in
terms of the agreement with experimental results. |
