Robot-assisted non-destructive testing of automotive resistance spot welds
Welding in the World, 2020A commercially available matrix phased array (MPA) ultrasonic imaging system was successfully integrated into a robot-assisted automated non-destructive testing (NDT) method for resistance spot weld applications. The NDT system utilizes a dual-time gate feature, where optimized time gate positions and widths were determined for near-normal incidence ...

Dynamic electrode force control of resistance spot welding robot
2009 IEEE International Conference on Robotics and Biomimetics (ROBIO), 2009Although there has been always existing a strong desire to apply adjustable dynamic electrode force in resistance spot welding (RSW) over decades, technical limitation laid a barrier to its implementation and application. However, with the introduction of servo motor control technology into spot welding gun, this issue will not stay unsolvable any more.

Rigid-flexible coupling dynamics analysis of a spot-welding robot
2011 IEEE International Conference on Cyber Technology in Automation, Control, and Intelligent Systems, 2011This paper studied a dynamics simulation analysis method for a rigid-flexible coupling system of spot-welding robot. The 6R spot-welding robot multi-body dynamics model is created by FEA (finite element analysis) and MBD (multi-body dynamics) software.

Aluminum-steel dissimilar robotic arc spot welding with auxiliary insert
Welding in the World, 2019The authors have developed the novel process for joining dissimilar metals, which uses gas metal arc welding and an auxiliary insert or element. In this process, the element or the flanged steel rivet that has a hollow center is inserted into the pre-hole prepared in an aluminum alloy sheet for the first step.
