Title (EN) WELDING ASSEMBLY FOR FRICTION STIR WELDING
(FR) SOUDAGE PAR FRICTION A MOUVEMENT CYCLIQUE
Abstract:
(EN) The invention relates to a welding assembly for joining together workpieces (1, 2) along a joint between said pieces by means of friction stir welding. The welding assembly comprises a welding probe (9) intended to be advanced along said joint during the welding operation. The welding probe comprises a body (10) and a pin (20), the body being arranged to be pressed against the upper faces of the workpieces during the welding operation whereas the pin is arranged to be moved along said joint during the welding while being rotated and pressed against said workpieces. The pin (20) and the body (10) are also so arranged relative to one another as to be mutually movable, allowing said pin and said body to perform different movement patterns relative to one another.
(FR) L'invention concerne un système de soudage permettant d'assembler deux pièces (1,2) le long d'un joint formé entre ces pièces, par soudage par friction à mouvement cyclique. Ce système de soudage comprend un outil de soudage (9) destiné à être avancé le long du joint au cours de l'opération de soudage. L'outil de soudage comprend un corps (10) et une tige (20). Le corps est conçu pour être plaqué contre les faces supérieures des pièces durant l'opération de soudage et la tige pour être déplacée le long dudit joint pendant le soudage tout en tournant et en étant appliquée sur les pièces. La tige (20) et le corps (10) sont également placés de façon à pouvoir être déplacés l'un par rapport à l'autre, autorisant ainsi la tige et le corps à réaliser différents mouvements l'un par rapport à l'autre.
