EFFECTS OF DIFFERENT STIRRER-PIN FORMS ON THE JOINING QUALITY OBTAINED WITH FRICTION-STIR WELDING

摘要

In this study, 20 different pins that could be employed in friction-stir welding were manufactured. These pins and the A17075 T6 material were joined with the friction-stir-welding technique. Tensile tests, microstructure and microhardness measurements, scanning-electron-microscopy (SEM) and energy-dispersion-spectrometry (EDS) analyses were conducted on the components joint by friction-stir welding. Designs of the weld and the tip that achieve the best performance were determined.
