Hardfacing
Application of high-abrasion-resistance alloys by welding is a method of repairing
machine parts or other metallic items that are subject to abrasive wear. Examples
include rails, turbine blades, excavator bucket teeth and conveyors in the mining
industry. It is often cheaper to repair such parts than to replace them by new ones, as it is
quicker and there is no need to hold stocks of spare parts.
It can also happen that a surface must be hard, while the underlying material must have
higher toughness. In such cases, it is common to apply the hard surface layer by
welding, which can be done either by automatic welding equipment or manually,
depending on the circumstances and the amount of welding to be done.
