Mobile welding machine AMS 200

Track-laying – welding technology

Technology Park
Technology Park

The ZW442-3148 two-way rail welding vehicle with the AMS 200 welding head from Schlatter is used for welding rails using the mobile flash butt welding process. The vehicle is designed for use on the Deutsche Bahn (DB AG) rail network and all other networks with identical track profiles and the same track gauge.

Functional Characteristics

  • Transportation of the welding truck on its own axle & integrated two-way system to the construction site
  • Mobile flash butt welding of vignole rails
  • The screw connection of the rail to be welded must be loosened, then the contact grinding is carried out to create the contact surfaces for the electrodes of the welding head
  • Position the welding head on the rail to be welded. Align the rail ends with each other, trigger the welding program and weld the rail ends by melting the base material and then forcefully pushing them together
