JTC Welding & Engineering ordered new fabricated blades and tooling from a UK manufacturer. Welding Alloys provided support in supplying the most suitable hardfacing wire for the task. ROBODUR K 650, one of our best-selling seamless copper-coated wires, was identified as the ideal consumable for this application to protect the shredder from wear. The hardfacing was performed using the ROBODUR wire, significantly improving abrasion resistance and offering an effective solution to withstand the demanding operating conditions of the shredder.
Additionally, for all the V-prepped fillet welds, the customer applied Welding Alloys' ROBOFIL R 71+ seamless flux cored wire, to ensure the highest integrity and quality of each weld required for the repair. While this comprehensive rebuild required a larger initial investment than the previous patchwork repairs, the result promises a variety of long- term benefits such as an extended service life and a drastically reduced Total Cost Ownership (TCO).
This project highlights both the effectiveness of Welding Alloys' products and the importance of addressing equipment wear and tear with appropriate, high-quality solutions. By opting for a complete rebuild with advanced materials, JTC Welding & Engineering is setting a precedent for maintaining critical recycling infrastructure and ensuring operational efficiency for years to come.
