Utilizing Friction Stir Welding (FSW) as one of the welding processes which can be defined as a protagonist of green technology in the industrial welding area. As can be seen from the process of creating the SAW, it has the following environmental and operational advantages over other welding techniques. For sustainability and efficiency minded industries, FSW is the right choice for many reasons as described in this article.

Environmental benefits of FSW
The technique that can be listed as a major strength of Friction Stir Welding is its environmental friendliness. FSW differentiates from other operative welding procedures in that it does not entail the use of materials like filler metals, shielding gases and fluxes. This helps to minimize wastage and also does away with the use of toxic substances that cause pollution of the environment. Moreover, having the FSW taking place below the melting point of the workpiece materials allows it to exclude the generation of emissions and fumes common with molten welding processes.
There is no requirement for pre-weld cleaning process which is another advantage of FSW inEnvironmental perspective. Convectional welding normally needs pre cleaning of the surface that usually involves washing with chemicals that results in making of waste products. Many of these steps are not required in FSW’s solid-state process thus making it more environmentally friendly.
Energy efficiency in FSW
Another advantage of FSW is energy efficiency that could be considered to be one of the main benefits of the method. The process of producing these components is not done through melting the materials but through a rubbing action that creates heat, sometimes this is far much more energy intensive. In this way, FSW can produce welded joints with better quality and using less energy as compared to other welding process. Besides, it also leads to the reduction of energy expenditure, which is a direct function of the efficiencies achieved at each step in the welding process.
In addition, FSW’s capability of creating sound, high integrity joints in a single run reduces the work that may require multiple welds or finishing processes. This though, also contributes to energy conservation, and general process optimization.
Economic and operational advantages
FSW has a number of economic advantages, not mentioned in energy savings only. There is no wastage of consumables and the process is also fast hence it is cheap for many applications in the industries. Also, the FSWed joints represent improved quality with possibly less requirement for post-welding repair hence even more cost saving.
With FSW ability to bond different materials and high strength alloys the technology finds its use in more industries. It makes it possible for the manufacturers to venture into new designs and materials while at the same time giving strong and dependable joints. Since industries are constantly searching for even better and less costly ways of producing even complex structures, FSW is well placed to meet today’s welding needs given it is relatively eco-friendly while yielding high results.
