A Simplified Design of Clamping System and Fixtures for Friction Stir Welding of Aluminium Alloys
Sound friction stir welds could be attained by using an active design of backing/clamping system with a proper selection of the welding parameters. This work presented a simplified design of fixtures and backing plates to be used for friction stir welding of aluminum alloys. The test-rig was const...

| description |
Sound friction stir welds could be attained by using an active design of backing/clamping system with a proper selection of the welding parameters. This work presented
a simplified design of fixtures and backing plates to be used for friction stir welding of aluminum alloys. The test-rig was constructed to prevent dispersal or lifting of the specimens throughout the joining process and to ensure uniform distribution of temperature along the plates. The workpieces were subjected to uniform lateral and vertical pressures by means of bolts and nuts.
Compound backing plates and pressure bars with additional side plates were included to increase the heat sink. Several coupons of dissimilar aluminum alloys AA7075 and
AA6061 were joined to inspect the validity of this design. The tests showed promising results with defects
-
free welds, good strength
and smooth surface finish without geometric imperfection and gap
creation
between the
welded
specimens
. Efficiency of the joint reached its maximum value of about 82%
with
respect to the ultimate strength of the
AA6061
alloy at 1100 rpm rotation speed and 300
mm/min feed.
These results
encourage using and improving th
e present
design for future
