It was established that intensive embrittlement of welded joints in the heat-affected zone occurs at low loading rates, close to creep ones. Increasing the deformation rate to 5mm/min decreases the sensitivity of metal of a welded joint to embrittlement. In welded joints with residual stresses, where hydrogenation takes place, the probability exists of the embrittlement of metal, which may lead to fracture of the welded joint Product Description popup.authors popup.nrat_date 2020-04-02 Close
