Summary

Worn austenitic manganese steel crossings can be repaired in service up to a certain limit by means of electric welding. The welding process can be either fully manual or automatic with programmable portable welding machines. When wear is greater restoration is still possible but the crossing must be removed from the line and fixed in a workshop. The paper describes a patented flexible high-productivity fully automated robotized plant, named Rail Switch Welding RSW®, where crossings are milled, welded and finished according to railway administration regulations. Special attention is deserved to the problems that were encountered and solved in milling a hard material with a slender and flexible structure such as a robot.
