Elektro-Thermit - Continuously Welded Track of the Highest-Quality Worldwide Using the Latest Measuring Devices and Services

Elektro-Thermit has provided continuously welded track, and ensured the highest track quality through the latest track measuring devices and services, for over 90 years worldwide.

Thermit®-welding connects rails of all profiles and grades in a safe and quick way. Depending on profile, load and grade of the rail, we offer our customers Thermit-welding processes; their implementation is characterized by very low demands in terms of time, material and manpower, and they also offer the highest standards of quality and reliability.

Elektro-Thermit delivers Thermit consumables, machines, devices and equipment for the different Thermit-welding processes for every type of rail. Additionally we offer insulated MT and ETW joints to provide solutions for the demands of the today's signal and security technology. Our portfolio also contains a large range of inspection and measuring technology products and services.

Track measuring devices

Elektro-Thermit's measuring devices and service business division offers you a large range of products and services for measuring stresses, stress-free temperature, track-geometry parameters, straightness, surface conditions, position and stability.

Using the most advanced devices and latest technologies, Elektro-Thermit carries out the greatest variety worldwide of measuring tasks and special work assignments.

Track-straightness measuring device

The Straightedge Compact RC (SEC RC) track-straightness measuring device provides measurement and complete straightness documentation of the running surface and edge, including all section-relevant data.

The basicSEC design has been approved for many years, and the SEC RC is an interesting new development that utilizes a PDA measuring computer.

Rail surface scanner

The electronic straightedge R2S rail surface scanner enables the application of the SEC and a corrugation measuring function, and therefore the measurement and documentation of short-waved unevenness.

Dual electronic straightness-measuring device

The Straight Edge Dual (SED) dual straightness-measuring device simultaneously measures and documents the running surface and running edge. After the measurement, the data is transferred to the measuring computer by Bluetooth and depicted, and can be documented later. On request, the device can be delivered with a PDA measuring computer.

Large-rail straightness-measuring device

The laser-straightedge Long Straightedge Dual (LSED) enables the straightness determination of rails of larger lengths (up to 50m). This allows measurements on both short-waved and long-waved longitudinal unevenness. The most accurate results are enabled by fixed-point laser technique and simultaneous measurement and documentation of running surface and edge.

Track and turnout geometry-parameter measuring trolley

Main track and turnout geometry parameters can be recorded with our measuring trolley TrackScan. These parameters include:

• Evenness
• Rail gauge
• Flange way
• Super-elevation
• Twist
• Versine
• Track coordinates via total station

Stress and stress-free temperature-measuring device for continuously welded rails

Elektro-Thermit's RailScan measuring service enables inspection of mechanical stress state and stress-free temperature. All measurements are carried out non-destructively without any obstruction and can be integrated into the operational procedure of the network operator.

This service is used for:

• Preventive determination of actual stress-free temperature / stress condition
• Control of cw-track production (e.g. final welds and re-establishment of required stress conditions)
• Complete railway inspection

This a complete measuring service including performance, evaluation and report creation.

Strain-gauge techniques for stress and stress-free temperature measuring

Strain-gauge techniques are used during the control of the cw-track production (stress-free temperature) and the subsequent lengthy stress monitoring. Presently, projects of national and municipal railway companies are metrologically supported.

Further measurement services provided are:

• Track position and stability measurements
• Track geometry testing
• Bridge and component testing
• Ultrasonic testing and inspections
• Calibration and inspection service

Elektro-Thermit also provides a rail-height and site-wear measuring device, and the Mo 40CL digital stick-on rail thermometer.
