TL;DR: In this article, the effect of welding processes such as GTAW, GMAW, and FSW on mechanical properties of AA6061 aluminium alloy was investigated, and it was found that FSW joints of AA 6061 aluminum alloy showed superior mechanical properties compared with GTAW and GMAw joints, and this was mainly due to the formation of very fine, equiaxed microstructure in the weld zone.

TL;DR: In this article, the effect of process parameters such as tool rotational speed, traverse speed and axial force on tensile strength of friction stir welded RDE-40 aluminium alloy was evaluated.

TL;DR: In this paper, two methods, response surface methodology and artificial neural network, were used to predict the tensile strength of friction stir welded AA7039 aluminium alloy, based on three factors, three-level, and central composite face centered design with full replications technique, and mathematical model was developed.

TL;DR: In this paper, the structure and mechanical characterization of a friction stir welded 409M ferritic stainless steel joint were carried out using optical microscopy, microhardness testing, transverse tensile, impact and bend tests were performed.

TL;DR: In this paper, the use of taguchi experimental design technique for maximizing tensile strength of friction stir welded cast aluminium alloy A319 has been discussed using ANOVA and signal to noise ratio of robust design.
