In the previous paper, the relation between the initiation of hydrogen-induced disbonding and the structure at the interface was investigated. As a result, hydrogen-induced disbonding occurred at the structure with 20-28% Ni^* equivalent. In this work, on the basis of Ni equivalent, the conditions necessary for prevention of hydrogen-induced disbonding were discussed in view of welding materials, the dilution ratio and the condition of post weld heat treatment. Hydrogen-induced disbonding did not occur at the structure with Ni^* equivalent less than 20% or more than 28%. On the other hand, hydrogen-induced disbonding can be prevented or lightened by controlling dilution ratio or the time of post weld heat treatment respectively.
