This enables them to achieve optimal results and build a strong reputation for safety and durability. Additionally, our experienced team provides project welding instruction services, offering hands-on guidance and support to ensure seamless execution, even in remote Norwegian terrains.
Driven by a customer-centric approach, RMTS is dedicated to fostering long-term partnerships by delivering exceptional products and services tailored to the unique needs of our clients. Whether you are looking for reliable thermit welding materials, expert training, or project support in Oslo, Bergen, Trondheim, or Narvik, RMTS is your trusted partner in achieving welding excellence.
How RMTS supports the modern rail infrastructure and marine ports of Norway under extreme Scandinavian climates.
Norway’s geography presents some of the most challenging conditions in the world for railway engineering. From the coastal fjords in Bergen to the high-altitude mountainous stretches of the Bergensbanen (Bergen Line) and the heavy-haul sub-arctic tracks of the Ofotbanen (Ofoten Line) near Narvik, the demand for continuous welded rails (CWR) has never been higher. Thermite welding (or aluminothermic welding) plays an indispensable role in maintaining the integrity of these tracks, ensuring safe, smooth, and uninterrupted transport of passengers and heavy iron ore.
In Norway, railway infrastructure is managed by the state agency Bane NOR. Any track maintenance or new rail installation must conform to strict safety standards, such as EN 14730-1 and EN 14730-2. The thermal expansion and contraction caused by seasonal temperature swings—varying from warm summer days to freezing sub-zero winter temperatures reaching down to -40°C in inland regions—put extreme stress on rail joints. RMTS engineered thermite welding powder and sand moulds are specifically designed to yield high-toughness welds that resist low-temperature brittle fractures, fulfilling the rigorous safety requirements of Norwegian rail networks.
Norway is at the forefront of the green transition, actively investing in expanding its electrified rail network to reduce carbon emissions from transport. High-speed rail initiatives and double-track expansions demand modern welding methods that guarantee long-term track reliability with minimal maintenance intervals. The industry is moving towards the adoption of pre-fabricated, one-shot crucible technologies that reduce field waste and human error, speed up installation times, and increase the safety of track maintenance crews working in hazardous conditions.
WHY CHOOSE RMTS
RMTS has a highly skilled R&D team that works tirelessly to ensure that we produce thermit welding materials that meet the specific metallurgical needs of each type of rail profile used in Norway, including UIC60 and 54E1.
In addition to its strong R&D capabilities, RMTS actively participates in railway projects across China and globally. The company collaborates with railway authorities, construction companies, and maintenance organizations to provide localized materials.
By participating in large-scale railway projects, RMTS contributes to the development and maintenance of high-speed rail, urban transit systems, and conventional rail lines, ensuring the safety and integrity of the rail infrastructure.
Furthermore, RMTS maintains partnerships with research institutions, universities, and industry experts. These collaborations enable RMTS to continually strengthen its R&D capabilities in advanced thermit welding technologies.
Deploying advanced crucible technology to optimize field efficiency and weld quality across Norway's railway networks.
Our single-use crucible technology minimizes preparation time and eliminates the risk of cross-contamination. Ideal for rapid night-time track maintenance windows in busy transit corridors like the Oslo-Drammen line.
Designed for multiple uses, this system offers an economical alternative for major track laying projects. Made with high-grade refractory lining materials to withstand multiple high-temperature aluminothermic reactions.
Aluminothermic welding plays a crucial role in modern logistics and transit. No matter the scenario, RMTS welding technology serves as a powerful support for promoting industry development and ensuring operational safety.
Planning your track welding project in Norway? Use our standardized calculation to estimate the required materials.
Thermit portion, sand mould, luting sand, and ignitors are the main consumables for aluminothermic welding. The general rule of thumb is: 1 weld = 1 set of consumables.
For example, for a 10km railway construction project using standard 12.5m rails in Norway:
Having an accurate estimate ensures that your logistically challenging projects in remote areas of Norway (such as Nordland or Troms og Finnmark) do not suffer from downtime due to material shortages.
RMTS's strong R&D abilities, coupled with its extensive involvement in international railway projects, demonstrate the company's commitment to providing advanced thermit welding solutions that meet the specific demands of the modern railway industry. We guarantee consistency, safety, and durability in every batch of thermite powder we ship to the Norwegian market.
RMTS is a passionate and progressive aluminothermic welding manufacturing company offering end-to-end guidance.
Aluminum thermite welding, also known as aluminothermic welding, is a specialized technique that utilizes an exothermic chemical reaction to generate intense heat for joining steel rail components without external power sources.
Preparation: Ensure the rail ends to be welded are clean, free from rust, and properly aligned. The gap size (space between two rails to be welded) shall be 26±2mm to ensure complete penetration of the molten steel.
Thermit welding materials will fail if exposed to water. All welding materials must be kept away from any moisture in storage, as well as during the pre-heating and welding process in damp or snowy Norwegian weather.
Thermit welding requires careful handling and storage of its materials. Keep portions and ignitors in a dry, temperature-controlled warehouse to ensure safety and optimal chemical reaction performance.
We offer a wide range of thermit welding materials, such as welding kits, sand moulds, one-shot crucibles, long-life crucibles, luting sand, and ignitors, ensuring consistent quality and reliable performance across Norway.
Our technical engineers are available to fly to Norway for hands-on training, track welding certification assistance, and custom project consultations.
