FlexiStir

Multi-functional FSW equipment

FlexiStir

The FlexiStir is a multi-functional FSW equipment, developed for In-situ experiments at Desy (Deutsches Elektronen-Synchrotron). This equipment have a few exchangeable components, like welding heads for specific requirements of each process variant or material/material combination.

The Flexi Stir Is being used for a wide range of solid-state process variants, like FSW, FSP, BT-FSW, FS, HFDB.

Technical Data
Six axes controlled by motors, one manually adjustable axis and two independently controllable spindles.
