AWS D14.7 (SURFACING AND RECONDITIONING OF INDUSTRIAL MILL ROLLS)

AWS D14.7’s implementation into ProWrite allows users the ability to enter, store, and access their Recommended Practices for Surfacing and Reconditioning of Industrial Mill Rolls documents as well as their welders from within ProWrite Welding Software.

AWS D14.7 is the Recommended Practices for Surfacing and Reconditioning of Industrial Mill Rolls developed by The American Welding Society for construction of these components.

An industrial mill roll can be defined as any roll or cylindrical body that transports, processes, guides or performs a function in creating a product in the heavy metals, paper, plastic, or lumber industries. These rolls can come in many shapes and sizes (as shown in Figure 1), and include, but are not limited to, table rolls, guide rolls, caster rolls, pinch rolls, leveler rolls, straightener rolls, bridle rolls, and blocker rolls.

This standard provides guidance, based upon experience, for preparing, building up and overlaying by welding, postweld heat treating (PWHT), finish machining, inspecting, and record-keeping of new and reconditioned industrial mill rolls. While mainly used in the primary metal-working industry, industrial mill rolls are also used in other applications. Because common practice predominately employs submerged arc welding (SAW), this document emphasizes SAW. However many of the principles are applicable, with suitable modifications, to gas metal arc welding (GMAW), flux cored arc welding (FCAW), and electroslag cladding.
