“…By sound weld is meant a joint that has neither internal nor external defects. From the analysis of the work provided on AA6xxx-T6 [4,5,6,7,8] and AA7075-T6 [9,10,11,12,13,14,15,16], it was evident the greater weldability of the former, as shown in Fig. 1.…”

The quality of friction stir welding joints is intimately related to the correct mixing of the stirred material. The material flow is strongly dependent on the plastic behavior of the welded alloy. For this reason, the friction stir weldability depends on the structure, microstructure and chemical composition of the base material. In this work, in-plane forces and acoustic emission signals were monitored while welding two heat-treatable aluminum alloys. The forces evolutions suggested possible continuous and intermittent material flow during friction stir welding depending on the welding parameters. The differences observed in the in-plane forces were corroborated by acoustic emission, confirming the modification in the material flow phenomenology. Therefore, differences observed in aluminum alloys' friction stir weldability are due to the plastic behavior at high temperature and medium-high strain rate. The higher the deformability of the aluminum alloys, the wider the weldability window in friction stir welding because of continuous material flow in an extended range of process parameters.

DP600 steel and AA7075-T6 aluminium alloy plates were joined using the friction stir spot welding process. The effects of different tool rotational speeds on the mechanical properties, intermetallic compound formation and interface microstructure of welded joints were investigated. The highest lap shear tensile load was obtained from the samples joined at a rotational speed of 1040 rpm (6.5 kN). It was determined that the tensile load of the welded joint decreased with increasing tool rotational speed. XRD analysis performed on broken surfaces, the intermetallic phase was determined to be Al13Fe4. As a result of Vickers microhardness tests, the samples joined at 1320 rpm and 1500 rpm, in the structure of which intermetallic compounds were determined by XRD analysis, displayed higher hardness values. In addition, when scanning electron microscope images were examined, it was determined that the cracks observed in the samples and the porosity both increased with increasing tool rotational speed.

“…Some researchers believed that tool shoulder diameter, tool tilt angle, and tool material were critical for successful welding processes [7]. Apart from the welding of various similar materials, such as Al-, Mg, Cu-, Ti-alloys, and steels [8][9][10][11][12], FSW can be utilized to join diferent grades of the same material and dissimilar material combinations [13][14][15][16]. Researchers have, in the past, experimented with FSW of diferent combinations of materials, such as aluminum alloys AA 7075-O and AA 5052-O [17], aluminum AA 3003 and AISI A441 steel [18], aluminum and stainless steel [19,20], aluminum and brass [21], copper and brass [22], polymer PMMA [23], aluminummagnesium alloy and polycarbonate [24], etc.…”

“…Te temper condition of the material to be welded also infuences the joint quality. İpekoglu et al [8] investigated the joint quality of FSWed aluminum alloy with O and T6 temper conditions. Te joints produced in the O temper condition exhibited comparably good strength, and lower strength was observed in the T6 temper condition when compared with the base metal.…”

Underwater friction stir welding (UWFSW) is an advancement of conventional friction stir welding, which is performed in air. The need for welding underwater calls for more information to be explored in the welding of different materials. The aim of this research is to investigate the UWFSW of 2 mm titanium sheet joints for their tensile and microstructural properties and compare them with the results of friction stir welding (FSW) performed in air. Also, nondestructive tests, such as radiography and dye penetrant tests, were carried out to identify the occurrence of any weld defects. The rotational speed of the FSW tool and its travelling speed were considered process parameters, while other parameters like the tilt angle of the tool, shape of the tool pin, etc. were kept constant. The results show that the welded joints with higher strengths were achieved at a lower travelling speed of 140 mm/min at a rotational speed of 400 and 500 rpm in FSW and UWFSW, respectively. The mechanical properties such as yield strength, tensile strength, and hardness are improved in UWFSW when compared with conventional FSW due to the proper mixing of the metal and effective cooling due to the water environment. In underwater FSW, the improved YS and TS values are observed, which are 95.9% and 75.1% of the base metal values, respectively, when the tool rotational speed is 400 rpm and the travelling speed is 140 mm/min. However, the elongation % is much lower in both FSW and UWFSW when compared with the base metal. These results are supported by microstructure and nondestructive test outcomes.
