Narrow Head Flashbutt Welder Ensures Precision in Confined Spaces

Rail welding operations require precision, efficiency, and adaptability to varying project requirements and conditions. Ensuring high-quality welds while maintaining operational flexibility is critical for seamless rail
maintenance and construction.

PRM’s investment in a narrow head flash butt welder provides a sustainable and practical solution for welding in confined spaces. The tall and narrow design requires minimal clearance, allowing for precise welding near adjacent rail or fixed objects.

Before

Traditional methods, particularly when welding turnouts, often posed logistical challenges, particularly in remote and confined space locations, making it near impossible to flash butt weld.

After

The slim design of the NHFBW head allows precise welding near adjacent rail and fixed structures. Mounted on a MAN chassis with Aeries hi-rail and an extended reach crane, improving access, weld quality, and efficiency.
