In this article, the research studies carried out will be presented, referring to the development of the process of joining metals, linear friction welding (FSW) in combination with adhesive bonding (AB), Friction Stir Weld-Bonding (FSWB), for overlapping joints (SLJ) and AA 6082-T6 aluminum alloy T-joints. Before the manufacturing of optimized joints was achieved, it was necessary to carry out several experimental weldings to select the FSW parameters for the lap and T joints. The current article intends to present the results obtained for the different tests carried out, as well as the discussion of these, regarding the improvement of the fatigue strength of lap joints using the FSWB process when compared to the FSW process. FSWB welding achieved a significant increase in quasi-static and fatigue strength when compared to FSW overlay, with 79.9% of the adhesive joint fatigue strength at 106 cycles, while FSW had 41.6%. bending of T-joints in an integral frame configuration will also be presented and discussed.

Weight reduction can be accomplished through the use of new light alloys and new structural designs [3]. To implement the use of lighter materials and innovative structural designs, it is necessary to develop new manufacturing processes. For decades, aircraft structures have been joined using a variety of joining techniques, including welding. The aeronautical industry makes little use of welding processes in primary structures due to the loss of mechanical properties related to large heat inputs, welding quality control (process reliability) and the impossibility of welding precipitation-hardened alloys (for example , AA2024 aluminum alloy), in Chapter 76
