hardfacing alloy should always be applied on top of the more ductile material. 39) When using self-shielded open arc wires, pay close attention to the am ount of electrical stick out used (contact tube to work distance). Short sickout dimensions less than 1/2" (12.7mm) or less can result in porosity. Most open arc wires can be operated at ...
2. When hard materials are used on soft base metals, such as mild steel, there is a tendency for the hardfacing layer to "sink" into the soft base metal under high load conditions. This may result in spalling of the hardfacing alloy. An …

Hardfacing. A surfacing variation in which surfac-ing material is deposited to reduce wear. (A non-standard term for hardfacing is hard surfacing.) Hardfacing Applications In hardfacing applications, a layer of surfacing metal is applied to reduce wear by increasing the resistance of a metal surface to abrasion, impact, erosion, galling, or ...
Most of the time, hardfacing is applied to used rebuild machinery, but even new equipment can be hardfaced to make it more wear-resistant. Hardfacing parts from equipment for many years can mean saving between 25-75% of the cost of replacement parts. On recent equipment, hardfacing can help to extend up to 300% of the lifespan of the parts.

Hardfacing is a technique that consists of depositing a hard layer to resist abrasion, erosion, scaling, high temperatures, cavitation and wear. Hardfacing is therefore a way to increase the lifetime of certain pieces in an economical manner. Building-up, on the other hand, is an operation to restore the dimensional form to a work piece.. The properties of the base metal chemical …
