The welded joints structural strength of the Al-Cu-Mg (D16M) alloys made using various add-on wires and technological inserts there are lovely in comparison with welded joints of the Al-Mg alloys. This is associated with the decomposition of solid solution and coagulation of the strengthening phase during welding thermal cycle and also the presence of hot cracks (during crystallization) and pore formation. The ability to predict the robustness of welded joints of such aluminum alloys by non-destructive methods using the parameters of local specific conductivity and local acoustic emission of a weld metal is revealed.5481 Product Description popup.authors Віра Володимир Володимирович Великий Петро Пилипович Головатюк Юрій Володимирович Долінська Ірина Ярославівна Канюк Юрій Ігорович Мельник Наталя Петрівна Осташ Орест Петрович Рудак Мар'ян Олегович Станкевич Ольга Миколаївна Толопко Ярослав Дмитрович Чепіль Роман Володимирович popup.nrat_date 2020-04-02 Close
