Repairing Crumpling and Wear Defects of Rails in the Zone of Electrocontact Welded Joints by Electric Arc Surfacing

The actual problem is the outage of rails in the continuous path made by electric contact welding. Among the main causes of the outages are defects of contact-fatigue origin, buckling, wear, and thermomechanical damage. A possibility to use electric arc surfacing to repair defective rails is analyzed. Keywords— defects of crumpling and wear of rail connections, electric arc welding, metallographic studies
