Strip overlay welding
DENDRIT employs two methods to remove the undulation wear and tear of the rails. The first method is using overlay welding and follow-up grinding of the rail head. For this purpose, an overlay welding machine has been created, which is used for sub-flux overlay welding – until its full profile is restored. Employing the same technology, the lateral wear and tear of the grooved rails can also be restored. The overlay welded metal ensures improved wear resistance of the new rail.
