Friction Welding

American Friction Welding (AFW) is a bi-metallic friction welder of dissimilar metals and near-net-shape parts. The company uses direct-drive rotary friction welding to deliver high precision, full strength penetration welds in the most demanding applications and industries. Dramatic cost savings result by reducing the amount of working material, machining, and surface finishing needed to produce finished metal components.

Rotary friction and inertia welding are a solid-state process joining two metal objects by applying rotational motion and 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 used to forge a metallic bond between the atoms of the objects. The overall molecular integrity of the original objects remains intact due to the narrow heat affected zone of this welding technology. Friction welding provides a complete cross-sectional weld without using fluxes or filler metal.

Automated friction welding is used to fuse aluminum alloy, brass, bronze, copper, nickel, silver, steel alloy, carbon steel, stainless steel, tantalum, titanium, tungsten, and many other metal alloys. It is successful in bonding two different metals where conventional welding may not work. It provides a high speed, lower cost weld solution to join motor shafts, axle shafts, prop shafts, gear to shaft, disc to shaft, solid round to solid round, pipe to pipe, and solid round to pipe welding. The process serves as an alternative welding method to brazing, electron beam, explosive, and butt welding.

Quality Assurance

Quality System Certification

American Friction Welding is ISO 9001:2015 Certified in the manufacture of custom friction welded assemblies and providing the services of material procurement, friction welding, CNC machining, and customized inventory programs. The company has a fully dedicated quality manager and quality department. Our dedication to quality is absolute and without compromise as we focus on delivering the highest-quality welded products and services available.

AFW emerged as the industry leader with a 100% customer satisfaction focus, state-of-the-art manufacturing equipment and processes, and a dedication to quality that is second to none. Every part we produce adheres to a Weld Procedure Specification (WPS) that dictates acceptable manufacturing tolerance parameters. Our welding centers equipped with advanced high precision controllers monitor every important weld variable during the weld cycle to ensure product conformance. Each weld cycle is measured and data recorded for future weld parameter review. Our quality assurance team performs ultrasonic weld inspection on a minimum 10% of all welded parts produced to ensure conformance and quality of working materials.

Repeatable Welding

Repeatable Welding A climate controlled facility delivers another level of consistency to our manufacturing process. Repeatable welding relies on controlled conditions, which includes its environment. All working materials acclimate to operating ambient temperature before production and per approved WPS.

Reliable Manufacturing

Reliable Manufacturing Our full-time maintenance team manages over $200,000 of spare manufacturing equipment parts. They provide preventive and predictive maintenance, minimizing unscheduled downtime and increasing on-time delivery of your product.

Precision Tooling

Precision Tooling AFW’s on-site toolroom is staffed full-time and is responsible for all tooling used at our facility, which provides more control and accuracy over our manufacturing process. The immediate response to any tooling issues that may arise reduces production downtime and helps to ensure on-time delivery.

Engineering Design Solutions

Friction welding dates back to the mid-50s - 63 years ago. For 33 years of that, AFW serves as an advocate, welding standards contributor, and a driving force of industry development. The technology has evolved into a sound welding alternative providing flexibility and cost savings across all manufacturing channels. Our engineering design team is here to evaluate your friction welding opportunity and provide straightforward answers, guidance, and solutions.
