Welding with AutoSeal® Moulds

AutoSeal® moulds are Pandrol’s newest aluminothermic welding innovation that streamlines the welding process. The built-in felt expands during the preheating phase of welding, creating a tight seal between the mould and rail. This completely removes the need for luting with paste or sand, whilst preventing welding leaks. They are the world’s first self-sealing moulds and bring numerous benefits including faster welding speeds, enhanced welder ergonomics, increased reliability, and reduced waste.
