Holland Automated Manganese Refurbishment (HAMR™)
Railroads report that traditional repairs to frogs and diamond inserts often only last weeks to a few months before requiring additional maintenance. These specialty track components are manufactured out of cast austenitic high manganese steel known for its excellent work hardening characteristics and high toughness. However, this material creates a unique challenge to repair or refurbish in the field as it cannot exceed 500 degrees Fahrenheit.
Holland’s Automated Manganese Refurbishment (HAMR) service includes pre-weld material removal using plasma cutting, rail grinding, and robotically controlled welding procedures to build back the damaged area.
This process provides improved welding results through lower heat input into the parent material, maintaining temperatures below 500 degrees. This refurbishment is higher quality, longer lasting and can be completed two to three times faster than the traditional repair welding process. This helps reduce costs and track maintenance time by eliminating the need for repetitive repairs.
