The significance of identifying faults in the welding process cannot be understated. As Hongbiao Dong, Professor of Materials Engineering at the University of Leicester, UK, said, 'Welding is one of the most important routes of joining metals and materials together.' It has long been speculated that solidification cracking during arc welding is linked to microporosities in the meshing zone of the solidifying welding pool, but with first experimental proof, we may be closer to prevention.
