FSW-US Hybrid Process Joining of Engineering Materials

Abstract:

The friction processing techniques, respectively those that use ultrasonic waves, have been for several years important research directions for ISIM Timisoara. The remarkable scientific results obtained through the development of complex research programs for these processes, the diversification of the application possibilities, the desire to improve the characteristics of welded joints, were the basis of the development of the US-assisted FSW hybrid welding process. The paper presents the results obtained by ISIM Timișoara regarding the development of the FSW-US hybrid joining process. Variants of original technical solutions for the necessary equipment are presented together with assessments regarding the conditions of application of the FSW-US process. Experimental results are also presented for FSW-US welding for pairs of materials such as aluminum alloys EN AW 5754 and EN AW 1200, respectively steel EN 10111 DD13. Comparative assessments are made between classic FSW welding and FSW-US hybrid welding, which highlight the advantages of applying the hybrid process.
