Automated Rail Welding as a Model for the Future in Track Construction

Robot-assisted gas metal arc welding for greater efficiency and safety in rail maintenance

Manual welding is one of the most complex procedures in the production of continuous welded rails. The fault potential is high; the handling of molten steel and the usually unergonomic posture of the welder leads to an increased risk of injury and frequently causes long-term health damage. Gas metal arc welding (GMAW) leads to a considerable improvement in safety, productivity and economic efficiency – provided it is applied correctly. Automation of this procedure with the use of robots raises the work quality and safety to a new level. Robel will put these benefits to the track from September 2020.


  • Optimised welding procedures and material properties for use on the track
    • Improvement in process quality
    • When does a welding robot become economical?
    • High material quality for durable rails
  • Automated GMA welding compared to the current processes in track construction
  • Safety for users, environment and traffic
  • User friendliness from welder to machine operator
  • Future-proof through automation
  • Conclusions


Since 1901 ROBEL has developed, manufactured and supplied track construction machines with a claim for safety and economic efficiency. This drives around 500 employees at the ROBEL premises in Freilassing, Germany, to create powerful machines and systems and deliver good service for the construction and maintenance of railway infrastructure systems all over the world.
