The article describes manufacturing technology of multilayer joints in terms of control the diffusible hydrogen content. Diffusible hydrogen content in deposited metal for multilayer welded joints made of covered rutile electrodes or covered cellulosic and basic electrodes was determined. It was found that after four beads, the diffusible hydrogen content decreases in the case of the first technology from 36 ml/100 g to 18 ml/100 g while in the second of about 40 ml/100 g to a level of 12 ml/100 g. The explanation of the mechanisms responsible for this phenomenon and directions for further study were proposed.Downloads
