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.

• Connection of almost all rails and large switch parts of different profiles and grades
• Guarantees the safe joining of rails while at the same time increasing travel comfort and the lifetime of the rails
• Execution of Thermit® welding as well as electric joint welding with the highest possible quality standards by welders with many years of experience

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:

• 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.

• Decades of experience
• Flexible and experienced welder teams
• Rapid repair of worn track curves without costly construction measures
• Extension of the service life through the use of highly wear-resistant filler metals
• No restrictions in network availability due to flexible working during regular train and traffc breaks
• Reduction of noise pollution by restoring the original profile

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.

• Grinding of new rails for the removal of mill scale or damage from construction work
• Removal of corrugations
• Deburring
• Re-profiling
• Removal of rail defects such as head checks, squats and wheel burns
• Acoustic grinding for considerably quieter train operations
• Switch grinding

• Improved wheel / rail contact for lower wear
• Lower noise emissions
• Preventative rail maintenance
• Flexible use of different grinding processes and devices
• High availability through excellent availability of grinding devices and grinding vehicles
• Rail gauge variable depending on device
• Longer rail service life
• Lower maintenance costs

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.

• Economic thanks to high wear resistance of the new rails
• Longer service life of rails and wheels thanks to low rail and wheel tyre wear
• Improved rail surface
• Formation of short waves delayed
• Tempering of all common grooved, flat bottom and customized rail profiles
• Flexible adjustment of customised curve radii
• Just-in-time delivery to the construction site

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.

• Measurement and documentation of the track geometry
• Measurement and documentation of rail profiles e. g. for acceptance of maintenance work
• Detection of rail defects by means of ultrasonic or eddy current sensor technology

• Effective and effcient detection of rail defects and track geometry application-specific measurement technology
• Evaluation and documentation with digital Dari® solutions
• Enabling predictive maintenance
