A tool is provided that is ca-pable of friction stir processing, friction stir mixing, and friction stir welding of high melting temperature and low melting tem-perature materials, wherein the collar is now divided into at least an inner and an outer collar coupled to the shank and the FSW tip, wherein new thermal barriers en-able expansion of the inner collar to be di-rected inward to thereby create compression on the FSW tip instead of allowing the FSW tip to become loose in the tool at ele-vated temperatures.
Linvention concerne un outil permettant le traitement par friction-malaxage, le mélange par friction-malaxage et le soudage par friction-malaxage de matériaux à haute température de fusion et à basse température de fusion. Le collier est maintenant divisé en au moins un collier interne et un collier externe accouplés à la tige et à lembout de soudage par friction-malaxage. De nouvelles barrières thermiques permettent de diriger lexpansion du collier interne vers lintérieur, afin de créer une compression sur lembout de soudage par friction-malaxage au lieu de permettre à lembout de soudage par friction-malaxage de prendre du jeu dans loutil à des températures élevées.
