Weld Roll Configuration (C): This configuration of four (4) rolls, (two (2) bottoms & two (2) tops), are normally found on larger tube/pipe mills from 3.000" O.D. and up, with wall thickness of .250" and above using High Frequency (HF) "coil and contact" welding
The high hardness ensures long life of the rolls. Typical materials of construction are aluminum oxide and silicon nitride. High speed non-ferrous metal tube mills are also employing ceramic rolls in the weld boxes for improved productivity and product quality. The rolls are produced in silicon nitride.
Benefits of Hardfacing Hardfacing is a low cost method of depositing wear resistant surfaces on metal components to extend service life. Although used primarily to restore worn parts to usable condition, hardfacing is also applied to new components before being placed into service. In addition to extending the life of new and worn compon-
