PTG introduces friction stir welding for EVs

Precision Technologies Group (PTG) introduced a number of Powerstir dual weld-head friction stir welding models specifically for use in the volume production of automotive battery tray floor assemblies from extruded aluminum panels. Aimed directly at manufacturers of skateboard chassis structures, the dual weld-head process ensures that a tight weld flatness tolerance is achieved during battery tray floor construction. The “matched” dual-force control systems and balanced upper and lower head welding parameters provide an even and stable welding process. The result is matched weld seams with balanced heat input.
