“…In these tests no dwell time was used, both pin and shoulder have been retracted as soon as the required plunge depth has been achieved. Table 2 summarizes the set of parameters used to produce the lap-shear and cross-tensile specimens and the maximum force observed in the lap-shear test [16]. The dimensions of the different joint regions (SZ, TMAZ and HAZ shown in Figure 5) were defined based in the actual values observed in a joint produced using welding condition number 6.…”

In the present study, the feasibility of the Friction Spot Joining technique on magnesium AZ31-O / glass fiber and carbon fiber reinforced poly(phenylene sulfide) joints is addressed. The thermo-mechanical phenomena associated with the Friction Spot Joining process promoted metallurgical and polymer physical-chemical transformations. These effects resulted in grain refinement by dynamic recrystallization and changes in local (microhardness) and global strength (lap shear). Friction spot lap joints with elevated mechanical performance (20-28 MPa) were produced without surface pre-treatment. This preliminary investigation has successfully shown that Friction Spot Joining is an alternative technology for producing hybrid polymer-metal structures.

The dynamic development of the friction stir welding (FSW) technology is the basis for the design of durabe joints inter alia in the aviation industry. This technology has a prospective application, especially for the aluminum alloys. It is suitable for a broad spectrum of permanent joints. The joints obtained by FSW technology are characterized by good mechanical properties. In this paper, the friction stir spot welding joints were analysed. The example of a structure made using this technology were presented. The lap joints made of 2mm Al 6061-T6 sheets were the investigation subject. The different spot welds arrangements were analysed. The tensile test were performed with optical deformation measurement system, which allow to obtain the plastic deformation field on the sample surface. The plastic strain graphs for the characteristic line passing through the maximum deformation were registered and presented. The experimental results were compared to the FEM numerical analysis. The numerical models were built with 3D-solid elements. The boundary conditions, material properties and geometry of the joints were identical as during experimental investigation. The mechanism of deformation of welded joints during tensile test was described and explained. It has been found that the arrangement of the spot welds with respect to the tensile direction has an important influence on the behaviour and deformation of lap joint.
