Tooling kit “Rotating shoulder” (pin & shoulder)

Standard tool with adjustable welding pin length for different component thicknesses
Tooling kit “Stationary shoulder” (pin & shoulder)

Tool with stationary shoulder and rotating pin (lower heat input, less burr formation)
Automatic cleaning station for tool SSFSW

Cleaning station for FSW tools - removes aluminum from the tools
Automatic tool changer SSFSW

Increased productivity thanks to fully automatic change of the FSW tool with standing shoulder
Automatic tool changer CFSW

Increased productivity thanks to fully automatic changer for classic FSW tools Automatic changeover by robot

Highly accurate, perfect weld seams thanks to precise path guidance

Ensuring a path accuracy up to 0.5 mm due to:

Use of special high-payload robots with high rigidity and long service life (KR FORTEC ultra)
laser-supported precise path calibration to compensate for path deviations caused by the different stiffness in the working area of the robot and the influences of different process forces
Almost no rework thanks to special tooling

Maximum FSW process control

The unique KUKA PCD 507 (Process Control and Documentation) system controls and documents all relevant process parameters during welding and has been transferred to the new intuitive KUKA.Web HMI. It thus guarantees:

100% reproducibility
100% quality monitoring in real time
100% process reliability (minimization of rejects)
100% documentation of the welding process

Process monitoring for all FSW path processes: Data export, process diagnosis and electronic archiving of all process data
