vibration mixing friction welding process

摘要

vibration mixing friction welding process. the invention relates to a friction welding process of mixing at least one first part in a metal alloy a with at least one second part in a dissimilar metal alloy b, in which that first and second parts are glued; with the aid of a rotating tool that moves with a speed called feed speed, a joint is made between this first and second part, characterized by the fact that this tool feed speed has at least two alternating modes in steady state , a first mode in which a first average advance speed v1 is used, and a second mode in which a second advance speed and average v2 is used, the speeds v1 and v2 being significantly different, typically at least 30% of the highest of the advance speeds, the weakest of the advance speeds can be zero. the welded connections according to the invention are particularly advantageous for making panels or profiles for the manufacture of transport vehicles.
