Abstract
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
