... Abstract This article describes the common defects associated with arc welds in the weld metal and the heat-affected zone (HAZ) of the plate. These defects include porosity, incomplete fusion, hot cracks, lamellar tearing, undercut, rollover, and inclusions. The article details hydrogen-induced...

... in the edge of the weld nugget at the faying interfaces. Under loading, the stress concentration due to the geometry can promote cracking near the nugget, either in the heat-affected zone, which often results in a weld pullout, or along the original faying interface for an interfacial failure. The load...
