The FSW-B/D Series consists of large gantry friction stir welding machines designed for oversized aluminum structures, EV battery trays, liquid cooling systems, and industrial structural components.
With high-rigidity gantry structures, high-torque spindle systems, and intelligent CNC control, this series delivers stable weld quality, low distortion, and reliable long weld seam performance for demanding industrial applications.
Our FSW-B/D Series is engineered for manufacturers requiring stable welding quality, large workpiece capability, and scalable automated production.
Compared with traditional fusion welding, friction stir welding (FSW) significantly reduces deformation, porosity, and weld inconsistency — especially for large aluminum structures requiring sealing performance and dimensional stability.
This series is widely used in EV battery systems, energy storage structures, industrial aluminum components, and thermal management applications.
