FSW Production System for Aluminium Intermediate Floors

For the production of aluminium intermediate floors, HAGE realized an FSW production system for transverse and longitudinal welding of individual aluminium extruded profiles.
01 / 03

The profiles are joined into complete floor elements using friction stir welding. FSW seams from above and below create a process-reliable welding concept for stable aluminium intermediate floors.

The system combines a universal clamping fixture with two FSW spindles and RPT function. This allows different profile geometries to be clamped flexibly and welded with controlled process management. The 8-axis configuration enables precise motion sequences for longitudinal and transverse welding.
