Effects of Diffusible Hydrogen Content and Hardness on Cold Cracking in High Strength Weld Metal

Abstract

The effects of the diffusible hydrogen content and hardness on the cold cracking in high strength weld metal were investigated. The diffusible hydrogen contents were influenced by welding parameters such as the voltage and contact tip-to-work distance (CTWD (Watkinson, 1969;Savage et al., 1976;Savage et al., 1978;Vasudevan et al., 1981;Savage et al., 1982;Yurioka and Suzuki, 1990;Di-jing et al., 1994).
