Abstract

The present study was focused on detecting weld defects in dissimilar joints made by friction stir welding. Radiography test and optical microscopy were used to evaluate the main defects. Coarse and continuous fragments of brass in aluminium matrix, tunnelling and void defects in vicinity of fragments were the main observed defects.

Authors like to appreciate Nicole Marjorie Kurtz who has played an important role in completion of this study.
