EWI Research Helps MTI Develop Low-force Friction Welding Solution for Rail
The rail industry has long been seeking a more dependable,
longer-lasting way to weld rail lines. The standard joining methods, flash-butt
welding and thermite welding, produce joints with short weld lives and require
To address this issue, EWI
conducted research on linear friction welding (LFW) as a potential method for
joining rail. The results, published by the Federal Railroad Administration,
demonstrated that using LFW improves rail weld quality.
Building on the findings and working with the support of
Technology Inc. (MTI) has developed low-force
friction welding, a new method that can produce stronger welds with
improved hardness, reduce cycle times, and extend weld life.
