Willke Track Service acquires patent on welding carriage ColdHeat 200

Willke Track Service has designed the welding carriage ColdHeat 200 together with the companies Ortec and Kjellberg. With this development we have revolutionised the maintenance of covered rail systems, because thanks to the ColdHeat technology, welding work can be carried out faster, cheaper and safer in the future.

Track maintenance with the ColdHeat 200

Instead of having to replace worn tracks at great expense, railway systems can be maintained automatically using the new welding process. Stressful shutdown periods or extensive planning are therefore no longer necessary. This is made possible by welding using inductive heat up to 200°C. Damage to elastic materials in the already covered rails is thus prevented. Furthermore, welding parameters are recorded with the help of an integrated computer. Consequently, the traceability of the entire welding process is guaranteed.

In order to inform the track construction industry about the functions of the welding carriage, we will present the carriage at the InnoTrans in Berlin from 20.09.2016 to 23.09.2016. Our technical director Ulf Langschwager will be available to answer questions from visitors to the fair.

Willke Group establishes welding department

Since 01.01.2013 Willke Track Service has its own welding department.

In the course of a future-oriented move of the Willke Group, a welding department was founded on 01.01.2013. Consequently, welding work in Germany and Scandinavia can be carried out within the group in the future.

For this reason, five welding teams and two construction supervisors will be working for the company from spring 2013 under the management of Ulf Langschwager. In addition, the department has its logistically favourable headquarters in Reinbek in the east of Hamburg. This enables us to be available for German as well as Scandinavian clients in a timely manner. Continue reading “Willke Group establishes welding department”
