Abstract

Hydrogen concentration distribution in multipass weld metal has been studied using hydrogen diffusion theory under various welding conditions. It is shown that hydrogen concentration distributions are predicted by means of parameters given by welding conditions, namely, heat input, plate thickness, weld metal width and so on. Influence of welding conditions on hydrogen concentration distributions is described.
