“…The 4043 electrode wire from the 4xxx group (5% Si) was used for welding busduct elements welding. Numerical analysis related to heat flow or welding stresses in aluminum alloys has been reported in the literature, but never related to the use of the micro-jet process in welding [13][14][15]. In the article, it was decided to subject the results obtained in real welding to numerical analysis in order to validate and verify the obtained results.…”

Aluminum alloys are lightweight and resistant to corrosion in the natural environment, which is why they are a proper material for responsible structures (in the civil engineering structures, automotive industry, electric conductors). Purpose of the paper was coupling MIG (Metal Inert Gas) welding process with parameters of micro-jet cooling just after aluminium busducts welding. There are given the main information about parameters of aluminum welding with the micro-jet cooling process. There were also put down information about the influence of various micro-jet parameters on the metallographic structure. After that, there were tested metallographic and some physical properties of welding structures (mechanical resistance, electrical conductivity). Welding with micro-jet cooling could be treated as a very promising process with high industrial applications. In addition, using Method of Fundamental Solutions, the influence of the heat flow process in WMD (weld metal deposit) after welding with micro-jet cooling was checked. The effect of micro-jet cooling on the grain refinement of weld metal deposit was carefully investigated. Controlled influence of the heat flow process in the welded joint will allow for proper selection of micro-jet cooling parameters. The article focuses on the mechanical and especially electrical properties of busducts welds made with innovative micro-jet cooling.

“…Band pattern is one of the features of BTFSW joining which effects on mechanical properties of joint. Hamilton et al [74] in their numerical simulation study on Al 6082-T6 compared torque-based approach with shear layer approach. Further, they proposed a modified shear layer approach which overcomes the limitation of above both methods and showed excellent agreement with experimental results.…”

Friction stir welding is a solid-state welding technique for joining similar and dissimilar material. Bobbin tool friction stir welding (BTFSW) is a variant of the conventional friction stir welding process (CFSW). Compared with conventional FSW, BTFSW eliminates all limitations of CFSW using a two shoulders configuration. Now, the need has arisen to review the work done on BTFSW to provide broader aspects of the technique to researchers. This paper aims at providing comprehensive insight on the BTFSW. The paper pays critical attention to tool material selection, design features of shoulder and pin surfaces, microstructure evolution, mechanical characterisation, derivatives, and challenges in this technique. Further, welding defects and future scope of BTFSW are also addressed in this paper.

Process parameters and base material thermal properties strongly affect peak temperature evolution in friction stir welding (FSW). This work develops a semi-empirical model for peak temperature estimation during FSW of aluminium alloys. Several bead-on-plate runs were conducted on AA5083-H111, AA6082-T6 and AA7075-T6. Different rotational and welding speeds were tested while measuring the temperature with a thermocouple embedded in the tool. A polynomial model was proposed with the model's coefficients strongly correlating to the material thermal properties. Additionally, a threshold peak temperature was defined to avoid cold defects by combining temperature measurements with joint quality information obtained from X-ray scans. The efficiency of the model and the defined threshold are proven by applying them to the literature.
