Wear Resistance and Component Design |
| |
Welding, as a joining tool is a mature technology, equally, traditional weld hardfacing for improving the life of wears components is a well-established process. Most often these are thought of as options for repair. But, the benefits of a welded solution can be designed into a component, tool or die from the outset.
Examples:
Within the Hot Strip Mill, process rolls are often manufactured from high carbon materials to extend life. Unfortunately, the repair of such rolls can be problematic. However, it is possible to redesign such rolls from low-alloy materials clad with Weldclad consumables to achieve improved life at reduced life-cycle costs.
Opportunities for component redesign are also apparent in the hot forging industry. Die block material selection is typically a compromise between the need for a tough, low-cost material for die support and a high-cost wear resistance material for the work surface of the impression. The Forgeweld process allows the manufacture of composite die blocks with a base of low-alloy material and an integral insert of high alloy material to maximise performance and reduce cost. |
