Welding Alloys Machines

FTR – Frog Top Rail

Automated open arc rail welding machine

Automated weld restoration of worn frogs and rails offers a more cost effective approach to extend track lifetime compared to replacing worn frogs or track. Welding Alloys FTR machine, with pendant machine control technology, allows fully automated control of the welding process
with little operator intervention.
