“…This FSW method has minimized the defects occurred by the conventional fusion welding of aluminium alloys and improved the joint quality and weld strength. Also, joining in this method is eco-friendly, safe, and non-hazardous, like TIG, MIG, and GTAW fusion welding methods [ 13 , 14 ].…”

“…FSW is a solidstate welding process where two components are plastically deformed and mechanically intermixed using a non-consumable rotating tool. FSW requires no filler material and hence, has no hazardous fumes [26], consumes significantly lower energy, and generates lower material waste compared to arc welding processes [27].…”

The traditional method of manufacturing propellant tanks for rockets and spaceships involves significant amounts of forging, and machining, making it expensive and environmentally unfriendly. A novel approach for manufacturing propellant tanks that reduces the need for machining and friction stir welding processes has been presented in this paper. This approach involves manufacturing a tank half starting from a single metal plate, using innovative and advanced metal forming processes such as hot stretch forming, magnetic pulse forming, hub forming, and integrated stiffened cylinder (ISC) flow forming followed by orbital welding of two tank halves. A life cycle assessment (LCA) study was conducted in accordance with ISO 14044:2006 standard using the ReCiPe 2016 Midpoint (H) method to compare the environmental impacts of the traditional and newly developed approaches for manufacturing propellant tanks. The results of the LCA study showed that the new approach based on advanced forming technologies reduced carbon footprint by 40%, cumulative energy demand by 35%, water footprint by 17%, and materials waste by 4% compared to traditional manufacturing. The lower environmental impact of the new approach was attributed to a decrease in friction stir welding requirements due to the implementation of advanced forming techniques that enable integrated tank production. This lowered the overall energy consumption in the novel approach by a factor of 1.5 and in turn resulted in lower environmental impact compared to traditional forging and machining-based method. Furthermore, a futuristic scenario that involves in-house tank production using the novel approach with minimal transportation of inventories was also simulated. Based on the LCA results, it was seen that the newly developed approach for manufacturing propellant tanks was more environmentally friendly than the traditional approach and its environmental footprint could be further reduced by implementing the futuristic scenario with minimal transportation. This novel approach is also expected to reduce the lead time and production cost of manufacturing a propellant tank. Hence, future efforts in cost assessment and further optimization of raw material and energy usage are recommended.

“…In contrast, Friction Stir welding doesn't require filler material, so if the proper procedure is followed, it can produce almost perfect joints without any defects [4]. M. A. wahid et al [5] reported that friction stir welding (FSW) offers significant environmental benefits such as eliminating the need for FW consumables, reducing toxic fumes and radiation, minimizing surface cleaning, and eliminating grinding waste. FSW also provides energy benefits by reducing fuel consumption in lightweight applications and allowing welding on larger material thicknesses.…”

Friction Stir Welding (FSW) is a solid-state welding technique that differs from the fusion welding methods as the melting of the materials to be joined does not take place. Moreover the absence of harmful fumes or toxic gases during FSW makes it an environmentally friendly process. The FSW process can produce high-quality welds and uses considerably less energy than any other arc welding process. Recent advancements have made it possible to use FSW to join polymers, and the resulting welds have demonstrated good mechanical properties. Moreover, FSW poses no health risks to welders, while prolonged exposure to an arc welding environment can be harmful to their health. In summary, this review article discusses the capabilities and quality of the FSW process, highlighting its advantages over traditional arc welding methods.
