Friction Stir Welding (FSW) Technology

Friction Stir Welding – More than Just a Superior Weld

Bond Technologies designs and builds best-in-class Friction Stir Welding (FSW) machines. Our highly engineered FSW systems and related services are sold across the globe for research & development and manufacturing production installations.

Why Friction Stir Welding could be the solution for you

FSW is an optimal choice when you want to weld lightweight alloys, minimize distortion, or want to automate your manufacturing process to improve production and efficiency.

Friction Stir Welding is superior to conventional welding methods in part because it works with previously “un-weldable” alloys of aluminum, steel, copper, nickel, and titanium. Not only does FSW weld dissimilar materials and alloys not compatible with traditional welds, but it also produces stronger joints. Metals processed with FSW have improved tensile strength, and less distortion compared to fusion welding.

How FSW Works

Friction Stir Welding (FSW) is a solid-state metal joining technique that offers numerous benefits across industries. Unlike traditional welding, FSW creates a stronger, tougher bond without the defects often associated with arc welding. FSW is a widely used solid-state joining process, initially adopted to weld aluminum alloys and now successfully applied to other materials, including copper and titanium.

FSW involves using a cylindrical tool with a profiled threaded probe, known as an FSW tool or pin tool, which is rotated and plunged into the joint between two metal pieces. Frictional heat softens the metals to a plastic-like state without melting them. The softened metals are then stirred together, creating a solid-state bond with minimal distortion and high weld strength. In general, FSW has been found to produce a low concentration of defects and is very tolerant to variations in parameters and materials.

Bond Technologies designs and manufactures FSW tools for a variety of applications and materials, including aluminum, steel, and copper. All FSW tools are manufactured according to Bond drawings and are inspected to ensure consistent, reliable performance, weld after weld. FSW Tools for Life Bond can provide a regular supply of tools for the life of a program, ensuring consistent results. FSW Tool Types Bond designs and builds conventional FSW tools, both one-piece and two-piece styles, fixed and variable gap bobbin tools, and stationary shoulder tools. FSW Tool Kits Bond can configure kits of FSW tools to cover different material thicknesses. FSW Tool Materials Bond can supply tools made from a variety of materials, such as H13, W360, W-Re-HfC, W-La, PCBN, and WC.

Since the energy required to soften the material is concentrated in the area where the tool is working, and the desired temperature is lower than conventional arc welding, this process uses significantly less energy.

Expand Product Design Options

The use of Friction Stir Welding with Bond Technologies makes new things possible.

FSW is a versatile and effective process for joining dissimilar materials. Its solid-state nature and numerous benefits make it a popular choice for industries looking to improve the strength, durability, and overall performance of their products.

Utilizing the latest in FSW technology, Bond’s FSW machines expand product design options for companies by offering a versatile, efficient, and high-quality welding solution for a wide range of materials and applications.

With FSW, it is possible to:

  • weld any aluminum alloy to any other aluminum alloy, in extrusions, forgings, castings, and rolled plates.
  • weld cast magnesium
  • weld 50mm (two-inch) thick copper in a single pass.
  • join aluminum composites with embedded hard particles without segregation of the constituents.
  • weld aluminum to steel, copper, and magnesium alloys.
  • weld titanium – cast to wrought to plate.

Advantages & Benefits of Friction Stir Welding

New Solutions

FSW provides opportunities for innovative solutions to traditional joining problems.

Defect Free Welding

The process mechanically disrupts oxide-covered surfaces, resulting in smooth and aesthetically pleasing welds.

Versatile Applications

FSW can weld complex contours and various joint geometries.

High Joint Quality

Solid phase joint, no shielding gas for aluminum alloys. Autogenous process – no filler metal.

Large Panel Welding

FSW accommodates welding of large parts, ideal for applications like ship decks and rail cars.

Production Friendly

Easily controlled and eco-friendly process: Fully mechanized with minimal skill requirements, low energy costs, no fumes or sparks, and easily monitored parameters to reduce errors.

Low Distortion

Solid-phase welding greatly reduces residual stress and results in lower costs during post-weld processing.

High Fatigue Strength

FSW produces welds with superior tensile and fatigue strength compared to traditional methods. Its welded joints excel under repeated loading cycles, making it ideal for applications in aerospace and automotive industries where components face cyclic stress.

High Corrosion Resistance

Low process temperature reduces localized segregation of solute elements, thus improving corrosion resistance. It also improves corrosion fatigue properties.

Joins Dissimilar Alloys

FSW can weld dissimilar alloys that are incompatible with other welding processes. For example, FSW joins most aluminum alloys to each other. FSW offers the unique capability to weld high-strength aluminum series such as 2000, 6000 and 7000. This is not possible with other welding methods. It can even be used to weld aluminum to steel.

Strength & Ductility

In aluminum alloys, FSW can improve static strength when compared to arc welding. In many alloys, FSW exhibits greatly improved ductility over arc processes.
Bond Technologies and Posiva The CW-15 Canister Welder is a groundbreaking solution in nuclear waste management. Designed, manufactured, and installed by Bond Technologies, it’s the world’s first welding machine capable of safely sealing nuclear fuel canisters for long-term storage. This machine is part of the world’s first permanent geological repository for nuclear waste, located in Finland, where nuclear fuel rods are sealed in two-inch thick copper canisters and buried 420 meters underground. Using Friction Stir Welding (FSW), the CW-15 provides a leak-proof seal that ensures the safe containment of nuclear materials for up to 100,000 years. The CW-15 Canister Welder represents a major milestone in both environmental protection and advanced manufacturing.
