Das von Pandrol entwickelte und patentierte Startwel® Zündsystem ermöglicht es dem Schweißer, die Schweißladung leicht zu entzünden, um den Gießprozess der aluminothermischen Pandrol-Schweißung einzuleiten, und ersetzt die traditionelle „Wunderkerzen“-Zünder-Konstruktion.
Das Zündsystem ist so konstruiert, dass es genau in die runde Öffnung im Deckel des Pandrol-Tiegels passt.
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.
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.
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.
