“…In particular, the welded joints joined with the welding feed rate of 219 mm/min and the rotation speeds of 1000 rpm and 2000 rpm, using both stirrer tips, have a low fatigue strength and close to one another. Similarly, Sarsilmaz et al [19], stated that welding parameters such as stirrer tip and rotation speeds, and feed rates have significant effects on fatigue strength.…”

Defects such as porosity and cracking are serious problems in the joining of aluminium and its alloys by melt welding methods. In this case, it is important that the aluminum pairs are welded by friction stir welding (FSW), which is depend on joining at a temperature below the melting temperature by means of a stirrer pin. In this study, AA5182 pairs were joined in the different welding parameters by FSW. The effects of tool pin profily, feed rate and rotation speed on the temperature, force and vibration formed during welding were experimentally investigated. As the rotation speed rised, the temperature increased and the welding force decreased. But, with increasing feed rate, the temperature decreased and welding force and vibration have increased. Mechanical properties of the joints were adversely affected by low temperature, high welding force and high vibration.

Butt joints made of 6061-T6 Al and AZ31B Mg dissimilar materials were fabricated using friction stir welding (FSW). Three welding techniques were used in the experimental process: method 1-Mg on the advancing side (AS), method 2-(Al on the AS), and method 3-(Mg was placed on the AS for the first welding experiment, and then the plate was rotated horizontally by 180° so that Al was placed on the AS for the second welding). Focus on the comparative analysis of the second welding and primary welding on the microstructure and mechanical properties of the joint. The results show that the joints with the secondary welding method have the characteristics of onion rings in the stirred zone (SZ), where there is a serious mixture of Al and Mg, and the degree of mechanical bonding is significantly increased. At the same time, the enhanced mechanical effect of secondary welding on the weld led to a change in the microhardness of the SZ. In the tensile tests, the strength of the secondary welded joint was increased to 120 MPa compared to the primary welded joint strength of 89 and 95 MPa due to the increase in the degree of mechanical bonding of the secondary welded joints and the increase in the level of mixing of plastic materials in the SZ. In addition, the type of fracture of the joint in all three welding methods is a brittle fracture.

“…This includes for both similar and dissimilar metals and alloys. There are numerous investigations that are being in progress which are looking into the compatibility of FSW on the dissimilar aluminium alloys [1][2][3][4]. However, it has been noted that there are many factors which compromise the quality and strength of the dissimilar joint.…”

The investigation on the fatigue behaviour of the processed friction stir welded AA8011/AA6082 dissimilar joint is reported in this work. The single-pass friction stir processing technique was applied on the friction stir welded AA8011/AA6082 and AA6082/AA8011 dissimilar joints. The friction stir processing was conducted under normal conditions (room temperature). The samples were prepared for different analysis using the waterjet cutter technology. The tests conducted include tensile, microstructural analysis, microhardness, fatigue and fracture surface morphology. The microstructural analysis revealed a correlation between material positioning and grain sizes. There was a notable decrease in grain size when AA6082 was positioned on the advancing side during processing. The tensile properties of the joint processed with AA6082/
