What Friction Stir Welding does

Friction Stir Welding is the FSW division of FPT Industrie Spa (Italian private limited company, headquartered in Camposampiero with operations in Santa Maria di Sala), delivering capital equipment and integrated solutions based on solid-state Friction Stir Welding (FSW) technology. FSW uses frictional heat and mechanical mixing to join metals without melting them, producing joints with superior metallurgical properties, no fumes or filler material, and lower energy consumption than fusion welding. The company markets five core machine platforms — StirWall, StirLab, StirSpace, StirRob, and the recently launched STIRCELL — covering gantry, Cartesian, robotic, and large-workpiece configurations, complemented by in-house designed welding tools (Fixed Pin, Retractable Pin, Stationary Shoulder, Bobbin Tool) and integration modules (sensorized FSW head, TUDX electrospindle) that retrofit FPT CNC machines into FSW systems. All hardware, tooling, and welding management software are developed in-house, leveraging over 50 years of CNC machine tool engineering heritage.

Revenue is generated through one-time machinery sales, hardware sales of tools and integration modules, and a four-part professional services suite spanning product and process design, plant design and productivity, training and production startup, and ongoing technical assistance. Go-to-market is exclusively direct enterprise field sales, targeting five verticals — Automotive & E-Power, Railway & Naval, Defense, Aerospace, and General Mechanics — with customers initiating contact via the website and engaging at industry events such as IMTS 2024. Marquee end customers include Thales Alenia Space (Lunar Gateway HALO module), Northrop Grumman (Cygnus spacecraft), Roscosmos, and FANUC America Corporation. The company participates in national and EU research programs (FIMSPAI consortium, Italian Space Agency, TWI, University of Naples) and operates a 76,000 m² manufacturing facility combining production with prototyping and metallurgical testing. Pricing is quote-based, customized per specification, with no public list pricing.

Configurable with fixed PIN, retractable PIN, and bobbin tool.
• Testina sensorizzata FSW (Sensorized FSW Head) A sensorized FSW head with morphology and interface identical to a standard tool that transforms an FPT milling machine into an FSW system. One or more sensorized heads are fully integrated by FPT, with no mechanical modifications required to the host machine. Uses monolithic tool technology and exploits the FSW-Ready predisposition of FPT CNC machines.
• TUDX - Elettromandrino dedicato per FSW (Dedicated Electrospindle for FSW) An electrospindle designed for FSW that transforms a machine tool into an FSW plant using an accessory warehouse. Features dual force measurement and is applicable to all FPT universal head models with electrospindle change. Uses monolithic tool and fixed-shoulder technology, with FSW cartridge managed in the accessory warehouse. Fully integrated by FPT without mechanical modifications to the host machine.
• Utensile a Pin fisso (Fixed PIN Tool) A monolithic FSW tool where shoulder and pin are machined from a single piece of tool. Suitable for very high applied forces and for welding workpieces with constant thickness. Provides standard welds with good quality and high feed rates, designed for high-thrust applications.
• Utensile a Pin retrattile (Retractable PIN Tool) A highly flexible FSW tool adapting to all weld path types. Allows welding of closed paths without leaving an exit hole and is suitable for workpieces with variable plate thickness.
• Utensile a Spalla stazionaria (Stationary Shoulder Tool) An FSW tool with a rotating PIN and a stationary shoulder. The PIN produces friction heating and joining by mixing material; the shoulder presses against weld seam edges, contains stirred material, and produces a smooth surface free of marks or external burrs. Particularly suitable for thin materials, e.g., below 1.5mm thickness.
• Bobbin Tool An FSW tool with a counter-shoulder that balances process forces. Ideal for very extended welds on uniform-thickness plates. Enables open linear paths on medium-to-thick materials and generally simplifies workpiece clamping requirements.
• Product & Process Design Comprehensive engineering service covering feasibility analysis, design support, prototyping, sampling, metallographic testing, experimental analysis, quotation support, and application study (machines, tools, equipment selection). Provides a single interlocutor to guide customers from initial project presentation through production startup.
• Design impianto e produttività (Plant Design and Productivity) Internal design of complete FSW plants based on the FPT product range. Delivers a full system of custom equipment and software, defines the production cycle, and provides productivity and cycle time evaluation. Turnkey plant supply.
• Formazione e avviamento alla produzione (Training and Production Startup) Personalized training on FSW machine usage and FSW technology, with hands-on support for production startup. Provides full technology transfer, enabling customers to operate FSW autonomously across all production phases. Leverages an intuitive graphical interface.
• Assistenza tecnica e supporto tecnologico (Technical Assistance and Technology Support) Ongoing technical assistance and continuous technological support for customer production. FPT technicians advise on project evolution and production process improvements to ensure production continuity.
