Friction Welding

Friction Welding

American Friction Welding (AFW) is North America’s largest subcontract friction welder with 18 high-precision friction welding centers. We are experts at welding dissimilar metals and near-net-shape parts using direct-drive rotary friction welding to deliver full-strength, deep-penetration welds in the most demanding applications and industries. Dramatic cost savings result from reducing the working material, machining, and surface finishing needed to produce finished metal components.

Rotary friction and inertia welding is a solid-state process joining two metal components by applying rotational motion and forging pressure to the objects. High temperatures generated by friction transform the point of contact into a plasticized state. This area is known as the weld interface. The pressure is applied to forge a metallic bond between the atoms of the objects. The overall molecular integrity of the original components remains intact due to the narrow heat-affected zone of the technology. Friction welding provides a complete cross-sectional bond without using fluxes or filler metal. Metal spin welding or rotary welding cycle times vary by metal type, shape, and weight.

We specialize in friction welding aluminum alloy, brass, bronze, copper, nickel, silver, steel alloy, carbon steel, stainless steel, tantalum, titanium, tungsten, and many other metal alloys. One object spins at a controlled rotating speed while the other is stationary. Friction heats the dissimilar material where they contact. It successfully bonds two different metals where conventional means may not work. It provides a high-speed, lower-cost solution to join motor shafts, axle shafts, prop shafts, gear to shaft, disc to shaft, solid round to solid round, pipe to pipe, solid round to pipe, and many other dissimilar shapes. The joining process is an alternative to brazing, electron beam, explosive, and butt welding methods.
