Hardfacing itself is a welding process that is used to apply a material
with increased hardness, ductility, erosion-resistance, and corrosion
resistance related to the base or parent material. Also, it is commonly
referred to as cladding or hard surfacing.

It is because of hard facing materials, improved properties which are a
part’s service life is prolonged and it can be applied to a new part in order
to offer a value-added feature which may also be applied to repair previously
deteriorated parts.
Let us look at some of the most popular procedures used to apply hard facing:
1. Flux-cored Arc
welding – It is a semi-automatic or automatic in some cases, arc welding process
which typically requires a continuously-fed tubular electrode containing a
flux. It is important to remember that flux is a chemical substance added to
the welding environment as a cleaning agent, flowing agent, purifying, and even
a combination of all.
2. Open Arc – Also known as
Gasless welding is a semi-automatic arc welding process that is chosen in field
applications because it is quick, easily transportable, and requires no gas
connection.
3. Gas Metal Arc
welding – Sometimes also known as MIG – metal inert gas welding – is a
semi-automatic welding process in which a consumable wire electrode and a shielding
gas are fed through a welding gun. With that, the constant voltage is mostly
used with this process.
4. Submerged Arc
Welding – This Hardfacing Welding Rod involves the formation of an arc between a
continuously fed wire electrode and a workpiece – similar to GMAW. Further, it
uses the process of flux to create protective gases and slag to the weld pool.
Before welding, a thin layer of flux powder is placed on the workpiece surface
itself.
