... by the laser pointer which is embedded in the welding torch nozzle, thus replacing the welding wire. It is important to note that weldment is not precisely positioned in the robot’s workspace using a welding fixture as it is a typical setting in robotic welding. The weldment, which is preassembled...

...Bao Mi; Charles Ume A real-time ultrasound-based system for controlling robotic weld quality by monitoring the weld pool is presented. The weld penetration depth is one of the most important geometric parameters that define weld quality, hence, remains a key control quantity. The sensing system...
