PTG’s Powerstir dual-weld-head friction stir welding machine delivers tight weld flatness tolerance

Precision Technologies Group offers the Powerstir dual-weld-head friction stir welding machine, designed to help ensure a tight weld flatness tolerance in the volume production of automotive battery tray floor assemblies from extruded aluminum panels.

That tight tolerance is essential to ensure that each electric vehicle battery cell sits level within its housing. The unit’s matched dual-force control systems and balanced upper and lower head welding parameters contribute to stable friction stir welding by both the upper and lower weld heads. This produces matched weld seams with balanced heat input, minimizing postweld distortion.
