Abstract

In this study, first, Diffusible Hydrogen of cellulosic electrode E8010-P1 and low hydrogen electrode E8018-G was measured by mercury displacement method according to ISO3690. Then, the effect of Preheating and Post-heating on the sensitivity to Hydrogen Inducedcold Cracking in welding of 18mm API5L X70 steel with these electrodes was investigated according to ISO17642-2. The results of visual inspection, penetrant test, metallographic examination, and hardness test showed that welding with cellulosic electrode leads to cracking unless both Preheating and Post-heating are applied. While in the case of low hydrogen electrode, cracking occurs only if no Preheating or Post-heating is applied.
