A plate tearing in steps beneath a weld

In welding, lamellar tearing is a step-like cracking that runs parallel to the surface of a rolled steel plate beneath a weld, caused by through-thickness shrinkage strain pulling apart flattened non-metallic inclusions in the base metal rather than failing the weld itself. Lippold's Welding metallurgy and weldability treats its cause and the joint designs and cleaner steels that avoid it. The referent is a base-metal cracking mechanism defined by its terraced path and its link to inclusions and restraint, sharing only the layered word with bone or lung organelles.[1]

Unit
The occurrence and extent of step-like cracking in the plate under a weld

Not applicable
