The preferred method for preventing fatigue crack issues in rail bolt holes and extending their service life.
The technique is superior to any other method of cold working bolt holes out there. This is because the process generates a more controllable distribution of compressive stress around a hole and through the bore, without damaging the integrity of the hole. Fatigue test data comparing as-drilled holes with cold expanded holes revealed that the cold expanded holes performed better in improving the fatigue life.
