Impact of diffusible hydrogen content on welding

Abstract

Hydrogen assisted cracking, or cold cracking is a common failure mechanism that affects most metals and alloys. Cold cracking is affected by several external and internal parameters, so determining the factors that contribute to crack formation is often difficult. This review examines the solubility, diffusion, and measurement of hydrogen based on domestic and international literature and summarizes the mechanism of cold cracking and the possibilities to prevent it.
