PTG has long used its considerable knowledge of the friction stir welding (FSW) process to assist automotive OEMs in producing lightweight, robust and aesthetic components for battery electric vehicles (BEV) and plug-in hybrid electric vehicles (PHEV). Aimed directly at manufacturers of skateboard chassis structures, the dual weld-head process developed by PTG ensures that a tight weld-flatness tolerance is achieved during battery tray floor construction.
This fully automated, dual weld-head FSW cell was delivered as a full turnkey project.

PTG can also provide FSW research and development along with full component prototyping.

Powerstir FSW manufacturing applications for electric vehicles include:
• Battery tray floor assemblies
• Battery trays and boxes
• Chassis and structural components
• Control box panels
• Vehicle body panels
• Brake regeneration systems
• Coolant units and heat exchangers
