Research on marine-grade aluminium alloys that undergo friction welding

Abstract

One of the most recent joining methods, 
friction stir welding is primarily used for the 
joining of aluminium alloys. Therefore, the 
purpose of this research was to examine the 
effects of various weld conditions on friction 
stir welding of marine grade 5083 aluminium 
alloy. Several studies were conducted to 
investigate the effects of tool traversal speed 
and tool rotation speed on the microstructure 
and mechanical qualities of the welded 
connection. It was discovered that the tool 
traverse speed had a substantial impact on the 
final properties of the welded joint. By 
smoothing out the grain, the TMAZ enhanced 
the welded junction's mechanical qualities. 
Although the rotation speed was kept constant, 
mechanical qualities were unfortunately lost 
when the welding speed was raised. Findings 
suggest that, with proper process parameter 
selection, a marine grade 5083 aluminium alloy 
welded joint of extremely high quality is not 
out of the question.
