Overlay welding using PTA or laser cladding is a technique commonly used to hardface components exposed to wear. State-of-the-art materials for these applications are nickel-based alloys with tungsten carbide particles embedded. Iron-based materials offer a cost effective alternative with lower environmental impact. The iron-based system offers different challenges compared to the nickel based system in terms of hard phase formation and stability upon processing.
Our range of hardfacing welding wires dedicated to increasing abrasion resistance. Many of our products are used in areas where safety is critical: shipbuilding, construction, railways, pressure vessels, power stations etc. As flux cored wires contain powder they can absorb the moisture phenomena, which could lead to welding problems, that could be avoided by respecting the storing and handling procedure or alternatively fixed by the following redrying procedure. Recently Welding Alloys Group in collaboration with Intellegens, looked at how machine learning can be used to achieve drastic improvement in performance of hardfacing welding consumables for Welding Alloys Group.
Over time, products may become subject to deterioration and reduced functionality due to wear. To combat this problem, a metalworking technique known as hardfacing can be used to improve the strength and prolong the lifetime of certain products. Hardfacing, also known as hardsurfacing, cladding , or overlaying, is the process of applying wear-resistant material to a component's surface. A harder or tougher material may be applied to the base metal of a new part or it may be applied to a worn-down product as a form of maintenance.
Hardfacing is a metalworking process where harder or tougher material is applied to a base metal. It is welded to the base material, and generally takes the form of specialized electrodes for arc welding or filler rod for oxyacetylene and gas tungsten arc welding welding. Powder metal alloys are used in PTA [ clarification needed ] also called powder plasma welding and thermal spray processes like high-velocity oxygen fuel coating, plasma spray, spray and fuse, etc.
