(Reproduced with permission from the publisher), b tailor welded blank (Land Rover and BMW
body panel) from 6xxx series aluminum [107] (Reproduced with permission from the publisher)
is used for various automobile components. AA5454 alloy having good corrosion
resistance is used in wheel rims and suspension components. AA5182 having good
formability and stress corrosion cracking performance used for body panels and interior. AA5154 is used for wheels, drivetrain components, and underbody components.
AA5022 is used for bonnets, oil pans, floors, rear fenders, roofs, and doors [106].
In 1998, TWI fabricated FSW tailor welded blank for Land Rover and BMW body
panel [107].
Magnesium alloys have been extensively used in the automobile industry for
engine bracket of Chevrolet Corvette and front-end of Jaguar XJ351 but due to the
high cost of magnesium alloys it restricts for mass production i.e. for a typical GM
vehicle, the consumption weight ratio of magnesium/aluminum is 4:123 [102].
2.7.4 Others Application I.E. (Nuclear, Shipbuilding,
Electronics)
Application of FSW in shipbuilding includes the joining of ship-panels and outer
body parts [108]. Honeycomb panels with the added advantage of high noiseabsorbing factors are used for ship cabin walls and railway wagons. Other industrial
applications include joints for the sailboat, refrigerators, helicopters landing platforms, oil-takeout platforms, ship’s mast, supports in yachts, and rolling stock for
railway transport, etc. [5]. The Shinkansen express (Japan) used finned panels floor
and wagon walls assembled using FSW [109].
Prefabricated panels through FSW is being used in the Freedom-class Littoral
Combat ships and the sea fighter of Nichols Bros. Special dedicated FSW machine
developed under joint treaties of the University in Adelaide (Australia) and TWI
for joining of curved joints at the nose part of a cruise ship (Patent WO98/38084,
Austria). The assembly comprises 5 mm thick AA5083 sheets. Hydro Marine fabricated friction stir welded roof panel as shown in Fig. 2.15 for delivery to Alstom
LHB (Germany) [107]. Another application of FSW is Siemen’s X-ray vacuum
vessel. FSW can weld 3D printed materials with a weld joint efficiency of 83.3%
