    Diffusible hydrogen content in the deposited metal of multilayer welded joints
    (2014) Fydrych, Dariusz Marek; Świerczyńska, Aleksandra; Rogalski, Grzegorz
    This article describes the manufacturing technology of multilayer joints in terms of controlling the diffusible hydrogen content. The 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 from 36 m l/100 g to 18 ml/100 g in the ca se of the first technology, and about 40 ml/100 g to a level of 12 ml/100 g in the second. The explanation of the mechanisms responsible for this phenomenon and direction s for further study have been proposed.
