Description
Friction stir welding (FSW) using a milling machine was employed to join AA-6063-T6 alloy (Al, 0.51%Mg, 0.42%Si) pipes (diameter 110 mm, thickness 5 mm) with the aim of eliminating ploughing problems, and weld zone microstructures were studied as a function of process parameters. The parameters varied were tool rotational speed (450-900 rpm) and angular forward speed (2-8 mm/s), and pipe welding experiments were conducted with and without a supporting disc. Optical microscopy was used to observe the microstructure (including grain size and porosity) of the HAZ, TMAZ (thermomechanically affected zone) and dynamically recrystallised zone. The effect of process parameters on the outer surface temperature of the welded pipe was studied also.
