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. This article discusses the basic issues related to the FSW technology. The macrostructure of a typical weld is presented. The influence of linear and rotational speed of the tool on the macrostructure of the weld was analyzed (cross-sectional shape, presence of defects). The process of "onion rings" formation in the weld nugget was characterized, taking into account the influence of technological parameters on their morphology.

Keywords:

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