Abstract
The invention relates to a process for the friction stir welding of two panels (), using a welding device () having a retractable pin (), comprising the following steps: positioning the two panels () so as to be in contact over an overlap region () and keeping them in the desired relative position after welding; bringing the welding device into contact with the upper panel at the start of the welded joint; longitudinally welding the two panels, by moving the welding device as far as the end of the welded joint; continuing to move the welding device () along a path extending beyond the end of the welded joint; and retracting the retractable pin () so as to prevent the appearance of a weld hole in a portion of the path of the welding device () extending beyond the end of the welded joint.
