Explore our primary, certified consumables designed to deliver seamless joint integrity across high-load railway lines.
Chile represents one of the most dynamic and challenging terrains for railway engineering in South America. Extending over 4,200 kilometers along a narrow coastal strip, the country relies heavily on robust transportation infrastructure to fuel its massive export economy. The demand for high-quality tool welding equipment and reliable aluminothermic consumables is driven by three primary sectors: heavy-haul mining corridors, bustling maritime seaports, and expanding urban transit systems.
In the northern regions, such as the Atacama Desert, heavy-haul freight railways transport millions of tons of copper ore from high-altitude mines to major shipping terminals. These tracks are subjected to extreme temperature fluctuations and massive axial loads, requiring continuous welded rails (CWR) that can resist thermal expansion and structural fatigue. Standard rail joints are highly prone to wear under these conditions, making precise thermit welding technology the gold standard for track maintenance and construction.
Engineered to withstand the extreme environmental changes and high-stress cycles typical of the Chilean Andes and coastal ports.
As Chile continues to invest in state-sponsored infrastructure programs (such as the "Chile sobre Rías" plan), the modernization of passenger and freight networks is accelerating. The Empresa de los Ferrocarriles del Estado (EFE) is actively upgrading passenger lines between Santiago, Rancagua, and Chillán, demanding faster train velocities and smoother track profiles. These high-speed requirements necessitate specialized grinding, tensioning, and shearing tools to ensure perfect rail geometry.
Furthermore, urban transit networks, notably the Metro de Santiago, are continuously expanding to accommodate the growing metropolitan population. Metro systems demand extremely tight tolerances to minimize vibration, reduce noise pollution in residential areas, and protect delicate structural tunnels. The use of high-precision sand moulds, one-shot crucibles, and customized luting compounds ensures that every weld joint matches the original metallurgy of the rail, securing long-term operational safety.

Our One-Shot Crucible utilizes high-purity refractory materials that prevent slag inclusion during the exothermic reaction. Perfect for rapid deployment in remote mining zones across northern Chile where transport and cleanup logistics are constrained.
Designed for high-frequency maintenance depots and multi-joint projects, the Long-Life Crucible features multi-pour durability, reducing the cost-per-weld and minimizing consumable waste on major railway construction sites.
Thermit portion, sand mould, luting sand, and ignitors are the core consumables for aluminothermic welding. The standard ratio is 1 weld = 1 set of consumables.
For example, for a 10km Chilean mining rail project using 12.5m standard rail segments:
Calculation: 10,000m / 12.5m × 2 = 1,600 sets of consumables
*Note: Additional buffer stock (typically 5-10%) is recommended to account for field alignment adjustments and test welds during local Chilean certification procedures.
Aluminothermic welding plays a crucial role in maintaining structural integrity across various heavy-duty transport systems. RMTS solutions serve as a powerful support for ensuring operational safety under the most demanding conditions.
Whether navigating the rugged topography of copper mines like Escondida or servicing the high-throughput crane rails at the Port of San Antonio, RMTS welding technology ensures zero-defect joints. Our specialized tool welding equipment, including hydraulic rail tensioners, precise profile grinders, and heavy-duty shearing machines, is optimized to meet the strict regulatory frameworks set by the Chilean Ministry of Transportation and Telecommunications.
RMTS provides over 20 years of experience as a passionate and progressive manufacturing company, ensuring your team has the skills and materials to succeed.
Preparation (Step 1): Ensure the rail ends to be welded are completely clean, free from rust, oils, and moisture, and properly aligned. The gap size (the space between the two rails to be welded) must be maintained at 26±2mm to guarantee complete molten steel penetration and fusion.
Thermit welding materials will fail if exposed to water. All welding portions, sand moulds, and additives must be kept away from moisture in storage, as well as during the active welding process. Store in dry, elevated, and well-ventilated warehouses.
Aluminum thermit welding, also known as aluminothermic or thermit welding, is a specialized technique utilizing an exothermic chemical reaction to generate intense heat (exceeding 2,500°C) to join steel rail components without external electrical power sources.
We offer a comprehensive range of thermit welding materials, such as welding kits, precision sand moulds, one-shot/long-life crucibles, sealing luting sand, and high-temperature ignitors, ensuring consistent quality, high tensile strength, and reliable mechanical performance under dynamic loads.
All RMTS products supplied to the Chilean market undergo rigorous non-destructive testing (NDT), including ultrasonic inspections and hardness profiling, to comply with both local EFE standards and international AREMA/UIC guidelines.
