Abstract


Friction Stir Welding (FSW) technology is increasingly used in aerospace, automotive, construction and other industries. It allows for safe, secure and long-lasting joining of materials that are difficult to weld or non-weldable with traditional methods. In engineering practice, these are primarily aluminium alloys.


Keywords


Friction Stir Welding (FSW); welding parameters; aluminium alloys; macrostructure; "onion rings"
