Rail alignment for welding of rail sections

Track-bound welding robots are used for maintenance and for the construction of new tracks. Thanks to the high degree of automation, the robots achieve rail welds of consistently high quality. scanCONTROL laser profile sensors are used to align the rail ends with each other. Robust laser scanners detect the profile from two sides and calculate the measurement values directly in the sensor. The relevant measurement values are output to the robot controller, allowing the rails to be raised and aligned. This ensures an exact alignment of the rails to each other.
