Friction Stir Welding
Friction Stir Welding (FSW) is a joining process that offers significant advantages over conventional arc welding methods, especially for thick aluminum vehicle structures. FSW utilizes friction between the welding tool and material to heat (but not melt), soften, and “stir” material across the joint to produce a solid-state weld. Concurrent Technologies Corporation (CTC) has repeatedly proven the superior performance and cost effectiveness of FSW relative to other conventional welding solutions. FSW circumvents or minimizes many arc welding difficulties. CTC has experience developing FSW processes and equipment for ground vehicle structures, trailer beds, ship deck structures, and more. FSW technology can also be used in the aerospace, automotive, robotic, and other industries.
Benefits of FSW Compared to Arc Welding:
- Creates improved mechanical properties (static, fatigue, damage tolerance)
- Reduces post-weld rework and fit-up issues
- Enables joining of dissimilar alloys with equal/better joint properties than joints made of lesser alloy
- Enables joining of different product forms
- Employs a much simpler process (Computer Numerical Control [CNC]) with fewer variables to control in manufacturing
- Requires less operator training than traditional aluminum arc welders
- Provides significantly higher production rates for thick materials
- Minimizes environment, health, and safety concerns – “Green”
