Method and device for welding rails
The invention relates to a method to replace a rail part of a railway wherein prior to severing the original the mechanical stress in the rail determined in situ, such as measured or calculated, which data is used during replacing the rail part by welding to bring back the original stress free condition. The rail is demounted across a predetermined length from its mounting to the foundation and temporarily brought in a curved shape, which curved shape is brought back to the original shape during uniting the rail by welding. Use is made of work train comprising an excavator and two wagons. Use is also made of a special clamping unit to press the rail ends against each other during butt welding.
