Friction Stir Welding Steel and Titanium Alloys for Aerospace and Avionics

Friction Stir Welding Exotic Alloys with Powerstir

Ever since the launch of its Crawford Swift Powerstir Friction Stir Welders, PTG Heavy Industries has been recognised as a global leader in this innovative way of jointing metals for applications as wide ranging as locomotive and passenger carriage panels, aircraft fuselage development, ship panel sections, truck bodies, fuel tanks, bulk containers and electronics enclosures.

Airframe and aerospace applications

Further research by PTG Heavy Industries, however, has taken the capabilities of Powerstir Friction Stir Welding further than ever before, to include the successful jointing of exotic steel and high strength titanium alloys for airframe and aerospace applications.

Aerospace-grade titanium of 3mm – 8mm

Using its proven PTG fixed pin tooling, PTG Heavy Industries has successfully welded aerospace-grade steel alloy and aerospace-grade titanium of 3mm and 8mm in thickness. Excellent results were also achieved working with various exotic alloys ranging from 2mm – 35mm in thickness, and in a number of complex configurations.

Says PTG Heavy Industries’ Sales Manager, Chris Cheetham: “The success of our research is such that we are now actively seeking opportunities to demonstrate the capabilities of Powerstir Friction Stir Welding on other bespoke alloys used in aviation. In particular, we have achieved good results working with exotic alloys of as much as 40mm in depth.”

Development of aircraft wings and bodies

Available in a range of sizes and capabilities, Powerstir Friction Stir Welders have found favour in experimental work, particularly that involving the development of aircraft wings and bodies. Powerstir machines have also been used in the advancement of space technology, with FSW welds enabling a reduction in the wall thickness of various components.

The results achieved by PTG Heavy Industries include:

  • Longitudinal welding of flat plates, using PTG fixed pin, retracting pin and bobbin ‘floating’ pin tooling technologies
  • PTG bobbin tool welding of aluminium aerospace-grade alloys
  • Rotary (C axis) welding of flat plates using PTG fixed pin and retracting pin technologies
  • Longitudinal seam welding of large diameter cylinders using PTG fixed pin and retracting pin technologies
  • Rotary (C axis) radial welding of large diameter cylinders using PTG retracting pin FSW technology
  • Rotary (C axis) welding of dome-shaped spheres using PTG retracting pin tool technology
