Proposed method comprises removal of worn-out flange and heating wheel rim to 200-250 C. Then, alloyed metal is built up on rotary wheel surface by means of crystalliser in electroslag hard-facing process using welding wire and flux with simultaneous built-up
What is Submerged-arc Welding? - TWI
This is a well established and extremely versatile method of welding. The electrode may be a solid or cored wire or a strip made from sheet or sintered material. The flux may be made by either fusing constituents to form a glassy slag (which is then crushed to form a powder) or by agglomerating the constituents using a binder and a corning process.

Torches using external wire feed are also available . It is possible to use both powder and wire feed coination if extra ordinary high deposit rates are required. Process Although many consider Plasma Transferred Arc System (PTA) as a Thermal spray process it is a high energy, inert gas welding process rather than a spraying process.
14.Plasma-arc welding (PAW) may be used for hard surfacing, overlaying and fully automatic butt welding.、。 15.Used for surfacing welding high-Mn steel, including various part of heavy impact abrasion resistance. ， 。

Optimization of Submerged Arc Welding Process: A Review
Wire sizes normally used for butt welding are 2.0, 2.5 and 3.0 mm, with wire separations of about 8 mm. DC welding, with the wire positive relative to the workpiece, is preferable, as this results in the best arc stability and least risk of porosity. When hard facing
