Fig. 6 Typical location for lamellar tearing in a T-joint. Stress across the plate thickness (the z- direction) occurs from strains that develop from weldmetal shrinkage in the joint. Lamellar separation is roughly parallel to the fusion line. Lamellar tearing can be prevented when More

... microfissures hot cracking lamellar tearing weldability THE FORMATION OF DEFECTS in materials that have been fusion welded is a major concern in the design of welded assemblies. Four types of defects in particular have been the focus of much attention because of the magnitude of their impact on product...

... 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...
