“…The process parameters had a significant influence on the shape and dimensions of hooking and/or partial bonding line. The analysis on the effect of individual process parameter showed that the plunge depth was the primary factor to create high lap shear force in similar Al joint [35,40]. When the plunge depth was restricted to the upper sheet, the hooking feature was not found to be significant to affect the joint static shear strength [8].…”

Refill friction stir spot welding, also known as friction spot welding (FSpW), is a solid-state welding process suitable for spot joining of lightweight materials. Through the efforts of improving joint quality for similar and dissimilar materials, for example, aluminum and magnesium, this joining technology is well developed. The joining mechanism and process characteristics of FSpW have been widely studied. However, the application of FSpW in industry has not been entirely successful. In this review article, the research of similar and dissimilar material joints, such as, Al/Cu, Al/Ti, Al/Mg and Al/ Steel, is summarized. The microstructural features and mechanical properties of the joints, welding tool and the application development are discussed in detail.

“…Researchers found that defects in aluminum alloy welds are less as compared to the fusion welds. Effertz et al [32] had been analyzed and optimized the process welding parameters in friction spot welding of 7050-T76 aluminum alloy. They stated that process parameters in friction spot welding were highly influential for quality responses of weldment.…”

Aluminum and its alloys have gained much interest in advanced industrial applications due to its excellent mechanical properties. Welding is one of prominent fabrication technique which has to be performed to make assembling of different parts to create one complete product. Welding of aluminum alloys (al) using traditional welding methods is difficult task due to un-weldability of aluminum alloys, more defects in weldment, presence of aluminum oxide film, etc. Friction stir welding (FSW) is a novel welding technique which was developed specially to join the aluminum alloys without melting of materials to be joined. Achieving the good qualities of welded joint with enhanced efficiency of the FSW process needs, proper understanding of principles of FSW. In the present chapter, various aspects of FSW of aluminum alloys related to effects of process welding parameters and temperature distribution during welding on mechanical and metallurgical properties of weldment has been presented. Extending applications of FSW in joining of dissimilar aluminum alloys and welding of al alloys with other materials has also been discussed. Concluding remarks are drawn from the study. From the study, it is stated that FSW is suitable for mass production welding method for joining of similar/dissimilar aluminum alloy materials in large quantity of similar products.

“…It was found that the best scenario is associated with first-in, first-out policy for all six machines, which was consequently determined as the optimal maintenance policy. Effertz et al [ 26 ] carried out the DOEs method to optimize the process parameters for friction spot welded aluminum alloy. It was found that the plunge depth is the leading parameter for obtaining the best lap shear force.…”

The amount of wasted polylactic acid (PLA) is increasing because 3D printing services are an increasingly popular offering in many fields. The PLA is widely employed in the fused deposition modeling (FDM) since it is an environmentally friendly polymer. However, failed prototypes or physical models can generate substantial waste. In this study, the feasibility of recycling PLA waste plastic and re-extruded it into new PLA filaments was investigated. An automatic PLA filament extruder was first developed for fabricating new PLA filaments. This paper also discusses the process, challenges, and benefits of recycling PLA waste plastic in an effort to fabricate new PLA filaments more sustainable. It was found that it was possible to fabricate PLA filament using recycled PLA waste plastic. The production cost is only 60% of the commercially available PLA filament. The tensile strength of the developed PLA filament is approximately 1.1 times that of the commercially available PLA filament. The design of experiments approach was employed to investigate the optimal process parameters for fabricating PLA filaments. The most important control factor affecting the diameter of PLA filament is the barrel temperature, followed by recycled material addition ratio, extrusion speed, and cooling distance. The optimal process parameters for fabricating PLA filament with a diameter of 1.7 mm include the barrel temperature of 184 °C, extrusion speed of 490 mm/min, cooling distance of 57.5 mm, and recycled material addition ratio of 40%.
