Aluminum alloy Al 2024-T3 were successfully joined using friction stir spot jwelding joining (FSSW). Satisfactory joint strengths were obtained at different welding parameters (tool rotational speed, tool plunge depth, dwell time) and tool pin profile (straight cylindrical, triangular and tapered cylindrical). Resulting joints were welded with welded zone. The different tools significantly influenced the evolution on the stir zone in the welds. Lap-shear tests were carried out to find the weld strength. Weld cross section appearance observations were also done. The macrostructure shows that the welding parameters have a determinant effect on the weld strength (x: the nugget thickness, y: the thickness of the upper sheet and SZ: stir zone). The main fracture mode was pull out fracture modes in the tensile shear test of joints. The results of tensile shear tests showed that the tensile-shear load increased with increasing rotational speed in the shoulder penetration depth of 0.2 mm. Failure joints were obrerved in the weld high shoulder penetration depth and insufficient tool rotation.

“…All factors are at optimal levels when the S/N response-ability is at the highest level [10]. ANOVA analysis is necessary for commenting on the S/N values acquired with tests, ANOVA analysis enables seeing more clearly the effects of the results acquired in accordance with the used factors and their related levels on product strength [28]. In Table 6, the results of the ANOVA analysis are shown.…”

At the joining of non-removable plastic parts, the methods such as friction welding, friction-stir welding, ultra-sonic welding, chemical joining, hot-plate welding use. Rotary friction welding, which is one of the friction welding methods, is generally used for joining the filter parts of water treatment devices. After rotating friction welding of the filter parts, semi-melted agglomerations are formed in the inner parts. To prevent semi-melted accumulation, weld joint profile design was developed in the ABAQUS program in the previous study. In this study injection molds had been produced and production according to weld joint profile design. The taken plastic presses were welded with the friction welding machine and the joint was controled and compared. It is seen that the semi-melted agglomeration was successfully confined. By performing Taguchi experimental method and ANOVA analysis on friction welding machine parameters the optimum pressure conditions were determined, aimed to carry out static and dynamic tests according to NSF standards and field tests by producing 1500 pilots product and it has been put into use. The lifetime of the developed filter depends on the material which was used in manufacture. In the next study, it is aimed to improve the lifetime of the developed filters.

Endüstride üretilen ürünlerin üzerinde çok çeşitli kaynaklı birleştirmeler yapılabilmektedir. Klasik ergitme kaynak yöntemlerinde oluşan sıcaklığa bağlı olarak kaynak bölgesinde gözenek, sıcak çatlak, yüksek ısı girdisi nedeniyle çarpılma ve kimyasal element kaybı gibi problemler meydana gelmektedir. Sürtünme karıştırma nokta kaynağında bu hatalar elimine edildiğinden dolayı farklı malzemelerin birleştirme işlemlerinde sıklıkla kullanılmaktadır. Yöntem ile hem aynı cins hem de farklı malzeme kombinasyonlarında kaynak yapmak mümkündür. Sürtünme karıştırma nokta kaynağı, birçok avantajı nedeniyle, otomotiv ve havacılık sektörleri dâhil olmak üzere çeşitli endüstrilerden büyük ilgi görmüş olan bir katı hal kaynak prosesidir. Al, Cu, Mg ve polietilen gibi malzemelerin kaynağı bu kaynak yöntemi ile sorunsuz bir şekilde yapılabilmektedir. Bu çalışmada, nikel kaplanmış ve kaplanmamış AA2024-T3 levhalar sabit kaynak parametreleri kullanılarak sürtünme karıştırma nokta kaynak tekniği ile birleştirilmiştir. Elde edilen mekanik ve mikroyapısal deneyler sonucunda birleştirilen parçaların mekanik özellikleri değerlendirilmiştir.
