4.1.8 Variations in FSW Process
Low v and high F z and torque on the workpiece are some of the major concerns
related to the process that limits the use of the process. Use of larger size machinery,
wear of tool at high temperature, welding of high-strength application materials,
etc. are challenges that restrict its use to its full potential. To address these issues,
continuous improvement and development have been made in the field of FSW with
every passing day. The issues related to process, tool, and machine are addressed in
some of the below-mentioned developed versions of the FSW.
• Stationary shoulder friction stir welding (SSFSW)
• Reverse dual rotation friction stir welding (RDRFSW)
• Bobbin tool friction stir welding (BTFSW)
• Friction stir spot welding (FSSW)
• Refill friction stir spot welding (RFSSW)
• Hybrid FSW processes.
4.1.9 Applications
Shipbuilding and offshore Freezer panels, ship, and oil-rig panels, the hull of an
ocean viewer vessel, honeycomb and corrosion resistant panels, deck panels of ships,
landing pads and vessels, etc. are commonly welded by FSW in recent times, in
different countries like the USA, China, Australia [25–27].
Aerospace Fuel tanks for spacecraft, aircraft fuselages, and wings are also welded
by FSW for defect-free joints [25, 28].
Railway Aluminium roof and floor panels and rolling stock, for the railway, are
fabricated by FSW [29].
Automotive Closures, tanks, suspensions, and pistons, and trailers used in automotive industries are done by FSW. The solid-state FSW process also joins wheels rims
and centre tunnel of fuel tank [25, 30, 31].
Other applications Cathode sheets, motor, and loudspeaker housings, heat sinks,
Heating, ventilating, and air conditioning units, backing plates for sputter targets,
vacuum vessels, panels are some of the other areas where FSW finds its application.
Components for the food industry, copper canisters for nuclear waste, etc. are also
welded by FSW recently [25].
The various benefits associated with FSW processes like low distortion, high joint
strength, smooth surface finish, flexibility in welding various materials and different
thicknesses are the reasons for the popularity of FSW in these sectors.
