What are the main applications of FSW in energy sector industry?

Friction stir welding (FSW) has found many applications in the advanced energy sector.
The FSW process is used for the manufacture of heat exchangers such as lamellar exchangers or plate heat exchangers.
In the wind industry, FSW has become a must for the manufacture of large lightweight panels such as wind turbine nacelles and blades.
It is used in the production of aluminum water cooling plates for solar panels.
The FSW process also facilitates the welding of copper components in series such as busbars.
