The use of robots for friction stir welding poses a number of challenges compared to conventional, rigid FSW machines. However recent advancements in robotics, together with new FSW techniques, have increased the potential of robotic FSW substantially.

2024年8月15日 · Commercial force sensors are mostly designed for six-axis welding robot and lack for high-force hybrid FSW robot. To address this gap, we developed a wireless multi-dimensional force sensing system for hybrid FSW robot. Our system utilizes elastomer and incorporates 8 pairs of strain gauges to detect tiny deformations.

2016年1月15日 · Hybrid force/motion control for friction stir welding is introduced. This survey presents a literature review on the machine and control systems applied in friction stir welding (FSW) with a special focus on the new trends, i.e., using robots and force control.

Friction Stir Welding (FSW) of is a well-established technology for production of lightweight parts, primarily in aluminium alloys, but the industrial applications are mainly limited to straight joint lines welded in custom-built machines. The possibilities for re-configuration and welding multi-dimensional joints are therefore limited.

This study aims to enable robotic friction stir welding (FSW) in practice. The use of robots has hitherto been limited, because of the large contact forces necessary for FSW. These forces are detrimental for the position accuracy of the robot.

2023年4月1日 · Robotic friction stir welding (RFSW) usually comes with a huge upsetting force, and the stiffness of the welding system distributes unevenly over the position, which leads to a large deviation of the plunge depth of the tool at the end of the robot.

2023年2月14日 · Purpose – This study aims to enable robotic friction stir welding (FSW) in practice. The use of robots has hitherto been limited, because of the large contact forces necessary for FSW.

At present, the robot FSW (friction stir welding) machine independently developed by Risong has obtained the CE certification and reached the internationally recognized standard. Based on its high-precision and high-torque robot body, Risong robot FSW machine is laying a solid foundation for high-strength and high-precision friction stir welding.

Robot-based friction stir welding: low-cost and weight-saving alternative to conventional riveting methods. We use sophisticated calibration algorithms to ensure that the weld is always executed exactly. They additionally facilitate the fast and simple setup of the system.

2004年2月1日 · The forces and torques associated with friction stir welding (FSW) are discussed as they relate to implementation of the welding process with industrial robots. Experimental results are presented that support the conclusions drawn from models developed by others.
