Friction Stir Welding
Friction stir welding is a solid-state joining process that uses frictional heat. Using this method creates a high-strength, high-quality weld. Friction stir welding has many applications, including, but not limited to aerospace, shipbuilding, aircraft, construction and architecture, and automotive industries.
Advantages of Friction Stir Welding
- Provides significantly stronger joints than fusion welding or mechanical fastening
- A solid state process leads to lower defects, distortion, and residual stress
- Cost effective - providing a dramatic increase in production efficiency
- Requires no filler material
- CNC controlled which allows for consistent results
- Allows for the joining of dissimilar alloys and high strength alloys more efficiently
- Environmentally friendly and safe
HFW team members have developed friction stir welds in virtually every alloy and joint group for customers in:
- Passenger rail
- Aerospace & Space launch
- Agricultural/heavy equipment
- Thermal Management
HFW’s friction stir welding and machining capabilities allow for a broad range of industries to be served and products to be made. HFW has years of experience making fully fabricated structures from large extrusions and is a leader in producing highly complex, small components from castings and plate. HFW has been a key service provider for the aerospace, architecture and construction, hybrid electric vehicle, marine, rail, thermal, and truck trailer industries for nearly a decade.
FUNDAMENTAL PROPERTIES OF FRICTION STIR WELDED AL 7136 INCLUDING EFFECTS OF POST-WELD ARTIFICIAL AGING
Recently, a new 7XXX series aluminum alloy designated 7136 has been developed by Universal Alloy Corporation (UAC) for aerospace applications. Base material properties of 7136 are compared to friction stir welded joint properties. Additionally an investigation into post-weld artificial aging and corrosion was conducted. The FSW joint properties and aging behavior of 7136 was also compared to 7075-T73 and some of the replacement alloys for 7075-T6 which have been identified by the Navy, specifically 7055-T74 and 7249-T76. Trends in the overall aging behavior of 7XXX series alloys, friction stir welded in the T7x condition are discussed. Preliminary results show that the corrosion resistance of 7XXX series alloys welded in the T7x condition can be significantly enhanced by the application of post-weld aging following FSW. Post-weld aging is also required in order to stabilize the microstructure in 7XXX series alloys, which would otherwise continue to naturally age indefinitely as indicated in the literature. Microhardness, electrical conductivity, tensile and exfoliation corrosion test results, as well as an assessment of the metallurgical characteristics, is presented.
