Mining haul truck suspension rods endure some of the harshest service conditions of any component in the machine. When they wear, scar, or fatigue, replacing them outright is expensive and can sideline production for weeks. At High Tech Reman, we’ve engineered a proprietary weld overlay process that restores rods to like-new condition while often outperforming the original design.
What Sets Our Process Apart
Unlike generic weld overlay methods which often wear early or crack, we’ve developed proprietary processes, including wires and flux combinations that are unique to High Tech Reman. These consumables were designed specifically for mining suspension rods, balancing:
- Strength for heavy cyclic loading
- Ductility to resist cracking under shock loads
- Machinability for precise final fits
This isn’t an off-the-shelf repair. It’s a process proven across thousands of rods in high-tonnage mining fleets with decades of results.
Why Our Weld Overlay Process is Critical for Suspension Rods
Suspension struts see intense impact and flex. A surface coating alone isn’t enough. Our proprietary weld overlay:
- Metallurgically rebuilds fatigued steel back into the rod
- Allows for thick metallurgical deposits to restore base material when coatings alone cannot safely be used
- Creates an engineered base for subsequent machining and hard chrome finishing
- Restores rods to factory size and tolerance — often with extended life
Results in the Field
Customers consistently realize 60–80% cost savings compared to replacement, along with faster turnaround and minimized downtime. More importantly, rods rebuilt with our proprietary process show reliability and 2–3 standard coating lives before needing our remanufacturing process again.
Bottom line: At High Tech Reman, weld overlay isn’t just a claim — it’s a proprietary engineered solution that keeps suspension rods in service longer, safer, and at lower cost.
