Advanced Welding Solutions for Rail Coach Manufacturing
High-performance Friction Stir Welding systems for rail coach structures - delivering strength, consistency, and production efficiency at scale.
Through FWT’s partnership with STIRTEC, railway companies across the Americas, EU, India, Australia, and New Zealand gain access to advanced friction stir welding systems engineered for high-performance and rail coach applications.
Friction Stir Welding for Rail Coach Structures
Friction Stir Welding (FSW) is a solid-state joining process that uses a rotating pin tool to generate heat and “stir” the material of two components together along the bond line, creating a high-quality weld without melting the base materials.
Because the FSW process occurs below the melting point of the materials, manufacturers in the railway sector benefit from a more controlled and reliable joining process, including the following advantages:
- Ideal for large aluminum extrusions and panel assemblies
- Enables long, continuous welds with minimal distortion
- Improves structural integrity and fatigue performance
- Reduces post-processing and rework
- Supports high-speed rail, metro, and passenger coach manufacturing
For rail coach manufacturing, FSW offers a reliable solution for producing durable, high-integrity joints.
GG Series Friction Stir Welder
Discover FWT’s most versatile heavy-duty friction stir welding machine. The GG Series is built for large, complex rail coach structures and thick-section materials that many conventional friction stir welding systems cannot accommodate.
- Rigid gantry architecture for maximum stability
- 5-axis gimbaled weld head for true 3D welding
- Handles oversized components and complex geometries
- Optional extendable rail system, machine-based, and high-capacity rotary table
LS Series Friction Stir Welder
The LS Series delivers unmatched performance for rail coach panels, extrusions, and long, continuous welds. This machine supports efficient, repeatable stir welding on large components where consistency and throughput matter most.
- C-frame design with modular base to scale the machine footprint
- Optimized for long, continuous welds
- Optional dual-head configuration for high throughput
- Ideal for structural panel assemblies
Digital Control for Consistent Weld Quality
STIRlytics® strengthens weld consistency by bringing advanced digital process control to FWT’s friction stir welding machines. STIRlytics® weld controls achieve precise, reliable welds by providing the following:
- Closed-loop force and position control
- Real-time weld monitoring and traceability
- ISO 25239-compliant weld quality
- Built on SIEMENS Sinumerik ONE CNC controller
- Remote diagnostics and Industry 4.0 connectivity
For manufacturers producing critical railway components, STIRlytics® helps ensure every weld is backed by data, consistency, and the advanced technology needed for long-term performance.
