2. 1. Feedback Control of Robotic Friction Stir Welding

   Author : Jeroen De Backer; Gunnar Bolmsjö; Anna-Karin Christiansson; Jorge Dos Santos; Högskolan Väst; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Friction stir welding; Process automation; Temperature control; Force control; Deflection model; Robotics; Svetsning; FSW; processtyrning; temperaturstyrning; robot; utböjning; kraftstyrning; Industriell arbetsvetenskap; Industrial engineering; Manufacturing and materials engineering; Produktions- och materialteknik;

   Abstract : The Friction Stir Welding (FSW) process has been under constant developmentsince its invention, more than 20 years ago. Whereas most industrial applicationsuse a gantry machine to weld linear joints, there are applications which consistof complex three-dimensional joints, requiring more degrees of freedom fromthe machines.
