Abstract
Hydrogen distribution in multipass submerged arc weld metal has been measur ed and analysed. The measurement of initial hydrogen content in a molten po ol by obtaining samples directly from the pool shows that the effect of dil ution on the initial hydrogen content can be neglected The transient hydrog en distribution in multipass weld metal has also been measured. This can be fairly well explained by the present hydrogen diffusion model using the tw o-dimensional source solution.
