发明名称 PULSED FRICTION STIR WELDING METHOD USING AT LEAST TWO ALTERNATING MODES, EACH OF WHICH HAS A FEED RATE, THE MEAN FEED RATES BEING SIGNIFICANTLY DIFFERENT
摘要 The invention relates to a method for the friction stir welding of at least one first part, made of a metal alloy A, to at least one second part, made of a different metal alloy B, wherein: - said first and second parts are adjoined; - said first and second parts are joined together by means of a rotatable tool moving at a rate referred to as a feed rate; and is characterized in that said feed rate of the tool has at least two steady state alternating modes: a first mode in which a first mean feed rate V1 is used, and a second mode in which a second mean feed rate V2 is used, the rates V1 and V2 being significantly different, typically by at least 30% of the highest feed rate, wherein the lowest feed rate can be zero. The welded assemblies according to the invention are particularly advantageous for producing panels or profiled sections used for manufacturing transport vehicles.
