High axle load – often every few minutes and in all weather: rails have to withstand a lot. Goldschmidt ensures a longer service life for your track systems with reliable and perfectly coordinated services.
Safety, economic effciency, travel comfort: the focus for all our services and products for the joining of rails and maintenance of railways. At Goldschmidt, we are constantly developing new methods, materials and equipment. This is appreciated by our clients and their customers, who transport their goods as freight forwarders or reach their destination as passengers – safely, comfortably, economically.
Thanks to our highly mobile equipment, our teams are particularly flexible. They can carry out all relevant welding and grinding work on rails, switches and on installed tracks where access can be diffcult – and that particularly quickly.
With the welding processes we have developed, practically every type of rail and switch type around the world, of various profiles and grades can be continuously welded. This guarantees a safe joint whilst, 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.
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 traffc. Therefore, the process is also predestined for high-speed and heavy-load routes.
As the inventor and global market and technology leader in the field of Thermit® welding, Goldschmidt has been setting standards for continuously welded tracks for 125 years. With our Original Thermit® welding processes, Goldschmidt enables the excellent joining of vignol, grooved and crane rails. Benefit from on-site services at the track construction site by highly trained and effcient welding teams. For internal quality assurance we use our digital Dari® systems, such as the Q-Weld app. This also allows us to provide our customers with quality data on completed welds on request.
For joint welding Goldschmidt also offers the E/111 process using rod electrodes and E/114 with self-shielded flux cored wire electrodes. These processes are mainly used for grooved and flat bottom rails on behalf of municipal rail operators or are used where Thermit® welding is not possible due to structural or physical constraints.
We use mobile working units for the necessary welding work. This also allows work during normal operations without significant restrictions.
We carry out the work on your track systems using the following welding processes, which we are constantly optimising:
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.
Use our professional grinding services to maintain your tracks and switches to benefit from considerably reduced rail life cycle costs and lower noise emissions from train operations.
Using manual and semi-automatic grinding, reprofiling and deburring machines as well as road-rail grinding vehicles, Goldschmidt maintains the quality of your railway tracks – quickly, effciently and with precision. Our highly trained grinding teams act flexibly and adeptly, and, thanks to our extensive fleet of vehicles, we can process your orders quickly and effciently.
We weld-temper new rails with highly wear-resistant materials – and 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 significantly reduces wheel tire wear by more than 90 %. We offer running surface welding for example on tight bends in dense residential areas, which substantially reduces noise emissions. The weld-tempering of new rails is made according to your requirements. For this purpose, we offer you various welding materials developed in-house for the running surface tempering – ET 2000® – as well as for the running edge tempering – ETEKA 5®.
This pays off for you in the long run with a longer service life for your rails, lower maintenance costs and lower noise emissions. And last but not least, it results in improved travel comfort and long-term reliability of rail operations.
Higher speeds, heavier loads and increasing demands on travel comfort – the requirements for railway tracks are steadily increasing. Our measurement and testing services ensure that you are able to assess the quality of your railway tracks at any time, guaranteeing you safety and economic efficiency.
With the devices developed by Goldschmidt based on our many years of experience, we manage the comprehensive geometrical inspection and documentation of rails and complete railway tracks. In order to evaluate measurements and make them globally available, data can be transferred directly to one of our Dari® software or database solutions and analysed.
