By a News Reporter-Staff News Editor at Robotics & Machine Learning Daily News Daily News-Research findings on robotics are disc ussed in a new report. According to news reporting from Beijing, People's Republ ic of China, by NewsRx journalists, research stated, "Robotic Friction Stir Weld ing (RFSW) technology integrates the advantages of friction stir welding and ind ustrial robots, finding extensive applications and research in aerospace, shipbu ilding, and new energy vehicles." Financial supporters for this research include National Key Research And Develop ment Program of China. The news journalists obtained a quote from the research from Beijing University of Technology: "However, the high-speed rotational process of friction stir weld ing combined with the low stiffness characteristics of serial industrial robots inevitably introduces vibrations during the welding process. This paper investig ates the vibration patterns and impacts during the RFSW process and proposes an active vibration avoidance control method for variable speed welding based on co nstant heat input. This method utilizes a vibration feedback strategy that adjus ts the spindle speed actively if the end-effector's vibration exceeds a threshol d, thereby avoiding the modal frequencies of the robot at its current pose. Conc urrently, it calculates and adjusts the welding speed of the robot according to the thermal equilibrium equation to maintain constant heat input."
