Holland?s Automated Manganese Repair (HAMR®) service includes pre-weld material removal using plasma cutting, and finish grinding. Our teams use robotically controlled welding procedures to build back the damaged area. This specialized welding process minimizes heat input to the base material, keeping temperatures below 500 degrees. This leads to a 33% reduction in heat input compared to conventional welding methods and enables us to deposit weld material at twice the speed without overheating the manganese. The repair is higher quality and longer lasting than the traditional repair welding process. This helps reduce costs and track maintenance time by eliminating the need for repetitive repairs. From a sustainability perspective, HAMR gives new life to frogs and diamond inserts rather than railroads replacing these components. Recent data has shown our HAMR-welded frogs have lasted over 12 months in service, with some exceeding 100 MGT.
