Abstract
The effects of hydrogen and microstructure on the cold cracking susceptibility of the heat-affected zone (HAZ) of carbon steel were investigated. Various carbon steel plates with tensile strengths of 400- and 500-MPa grade were employed, and the cold cracking susceptibilities of the HAZs were evaluated using implant tests. To investigate the effects of hydrogen and microstructure, implant test assemblies were produced with two types of welding electrodes (low-hydrogen and cellulose) and two different welding conditions (low and high heat inputs). The results indicate that the microstructure was more important than hydrogen in determining the cold cracking susceptibility of the HAZ of carbon steel.
