The FSW Peripheral Equipment comprises of a split roller surface sensor; inspection camera and an integrated cooling tool holder. The roller module allows loads to be applied to individual sheets of butt weld and thereby ensure consistency during the welding / processing procedure. The camera is mounted directly to the weld head. This ensures that the process can be recorded for archival or viewing at a later stage. The tool holder is used for welding of steel or other high temperature alloys with polycrystalline cubic boron nitride or tungsten rhenium. Without this tool holder, the alloys to be researched will be limited to those with low melting points.
