Cold Cracking of weldments

Abstract

This paper will discuss the definition of the cold cracking. By discussing it the reasons, the factors and how to avoid it, and comparison of testing the cold cracking sensitivity, the materials were used (high strength steel, C-Mn steel, and armored steel). Hydrogen cracking may also be called cold cracking or delayed cracking. The principal distinguishing feature of this type of crack is that it occurs in ferritic steels, most often immediately on welding or a short time after welding.
