“…Generally, the HAZ can be further divided into two regions including dissolution region with a higher hardness and over-aging region with a lower hardness due to the difference in precipitate. However, such regions cannot be clearly distinguished in this study and the investigation of Yan et al [28]. It may be because that the 7N01-T4 alloy possesses a relatively high natural aging effect after solid solution, and there is a time interval of two weeks between the hardness test and welding process.…”

7N01-T4 aluminum alloy was welded by metal inert gas welding and the influence of V-groove angle on joint fatigue properties was investigated. The results indicate that the volume of fusion zone (FZ) and the grains in FZ become small when the groove angle decreases to 50° from 70°. Most pores distribute at the FZ edge and fewer pores are formed in the small angle joint. The fatigue crack mainly initiates at the transition region between the weld passes due to the pore concentration. The small angle contributes to increasing joint fatigue properties, especially at the low stress level. The fatigue strength of 50° joint is 103.06 MPa which is 15.3% higher than that of 70°joint.

“…As it is minimal in the case of FSW, this joint microstructure is characterized by finer grains. Yan et al [20] also reported identical results for A7N01-T4 aluminum alloy, wherein FSW specimens exhibited higher mechanical properties (i.e., joint resistance and hardness) as compared to MIG-welded specimens ensuing from a finer grain structure in the weld zone. Apart from the grain dimensions, the size of the heat-affected zone (HAZ) is also minimized comparatively in the case of FSW as per an investigation published by Kumar et al [21] for mild steel.…”

Manufacturing tiny components into gigantic structures seems unimaginable without welding connections, whether it is for materials, parts, structures, or equipment. In the recent competitive market scenario, manufacturing industries are desperately looking for a viable alternative to fusion-based conventional material joining technologies, to improve upon cost-effectiveness along with performance. The present investigation is to evaluate the performance of structural steel thick plate joints prepared by advanced solid-state friction stir welding (FSW) over conventional metal active gas welding (MAG). The FSW experiments were carried out with different tool designs and configurations. The outcomes were evaluated in terms of microstructural integrity and mechanical joint resistance. Impressive results were obtained with FSW joints, characterized by an almost defect-free microstructure with a leaner heat-affected zone and higher joint resistance as compared to conventional MAG-welded joints.

“…Weld nugget pull out failure was observed as the major cause of failure in the AA2024 Al alloy as investigated by Karthikeyan and Balasubramanian [6]. In an investigation by Yan et al [7] there was plastic ring region, TMAZ, HAZ. In the paper titled characterization of dissimilar joints in laser welding by T.A.…”

Solid state welding processes are superior to fusion welding in the sense that they are free from temperature effects and some welding defects. Bimetallic joints are mainly preferred to reduce cost and ease of manufacturing. FSSW process finds its extensive applications in many industrial sectors where self weight is considered as a predominant factor such as automotive, airplanes etc. In this investigation, aluminum alloy (AA6061) and copper alloy bimetallic joint is tested for its electrical resistivity and mechanical strength
