Lamellar Tearing in Welded Steel Fabrication

Abstract

Lamellar tearing is a form of cracking that occurs in the base metal of weld due to the combined effects of the anisotropic characteristics of hot rolled steel plate and high stresses generated by weld thermal contraction acting perpendicular to the following plane. This cracking is usually associated with highly restrained tee or corner joints where the weld fusion boundary is parallel to the rolling plane of the plate.
