Vignole Rail Welding

Tested and approved against the European Standard EN 14730-1 Norm, the PLA Evo delivers improved metallurgical and mechanical behaviour, to optimise quality, lengthen the life of the weld and save time for the welder.

The HFP 36V is battery powered and fully automated for easier, more reliable operation: the ignition, timing and stop require no manual interference or flame adjustment.

AutoSeal® moulds are Pandrol’s newest aluminothermic welding innovation that streamlines the welding process.

HWR is suitable for repairing railhead defects between 25mm and 90mm wide and 25mm deep (depending on the rail profile), it can be used on both the parent rail and on electric flash butt welds, which often suffer from squats. It is also suitable for transversal defects, shelling and corner gauge. The aluminothermic weld process is carried out using specially designed moulds.

Beyond offering welding processes for all standard rail profiles, we also collaborate with customers to engineer bespoke solutions for special rail types that are less commonly used, such as the special rail grades used on metro lines including rubber-tyred rail, guide bar rail, conductor rail, and rack rail. We can offer portions, moulds and crucibles designed to your exact specification.

The process involves casting molten steel (produced through the reaction of iron oxide and aluminium) at a temperature exceeding 3,500 ˚F (1,950 °C) into refractory moulds designed to the rail specification.

This flat-bottomed rail is typically larger and designed to continuously support high volumes of weight.

Pandrol Connect consists of three modules: a mobile version for welders to record on-site data and for welding controllers to review data, an online monitoring app to review weld information from the office, and an online administration tool to apply settings to local standards.

The ignition system is engineered to fit precisely into the round opening in the lid of the Pandrol Crucible. Once the crucible is prepped and ready to pour, the Startwel® Ignition System can be placed in the lid and deployed safely by removing the metal clip grounding the prongs.
