Welding solutions

For safe and high quality railways

All over the world rails are welded using Goldschmidt expertise and new rails are weld tempered: for a longer service life and to ensure that all types of trains and trams run quietly, safely and environmentally friendly.

With our various welding processes nearly all rails and switches of various profiles as well as grades worldwide can be continuously welded by our well-trained welding teams.This guarantees the safe joining of rails while at the same time increasing travel comfort and the lifetime of the rails. As an end-to-end supplier we develop, manufacture and supply all components for our different welding processes.

Original Thermit® welding


Thermit® welding is and remains the most flexible, most reliable and most economical welding process for continuously welded rails and contributes significantly to a longer track life and greater safety in rail traffic. We continuously weld flat bottom rails, grooved rails and crane rails thanks to our Original Thermit® welding process. Read more here.

Maintenance welding

Wheel-bearing rail elements on subway systems, tramways, light rail and mainline networks and in particular on curved rails are subject to high loads. As a result we are frequently commissioned to carry out maintenance work with welding. A large part of this welding work is the reconditioning of switches and frogs and the removal of operational damage. We use mobile working units to do the welding on existing rails and switches. This also allows work during normal operations without significant restrictions.


The following welding processes used to carry out the work on your tracks are constantly being improved:

  • Submerged arc-welding
  • Manual arc-welding
  • Flux-cored wire welding
  • Repair welding process Thermit® Head Repair

Depending on your requirements, we use special machines to recreate the original profile or the profile you require on the welded rails after the welding.


Railway tracks subject to heavy loads experience high wear after just a short time. Our factory-tempered rails are perfectly prepared and last longer.

Highly wear-resistant materials are used to weld-temper new rails. The result is you receive a cost-effcient, comfortable and long-lasting product suitable for all new rail projects and renovation work. The reduced surface roughness of the used materials reduces wheel tire wear by up to 94 %. We offer running surface welding for use on tight bends in dense residential areas which substantially reduces noise emissions. This leads to long-term benefits with a longer service life for your rails, lower maintenance costs and lower noise emissions. The result is also improved travel comfort and long-term reliability of rail operations.

The weld-tempering of new rails is made according to your requirements.
