SCIENTIFIC-TECHNICAL SECTION

Dmitrik V. V., Grinchenko Ye. D., Syrenko T. O. � HAZ overheating area structure of the welds from thermally stable pearlitic steel

The peculiarities of ferrite welding heating formation in the incomplete recrystallization section structure of the affected thermal zones of the welds from the thermostable pearlite steels were determined. These peculiarities allow to prevent this formation by means of structure modeling.
Key words: ferrite, welding heating, incomplete recrystallization, modeling

Tsumarev Yu. A. � Effect of the off-centric tension on the stress state of a butt joint

Considerable effect of the off-centric tension, conditioned by the convexity occurrence in the single-side butt welds, on the welded joint�s stress state causing formation of the secondary tensile stress in the weld root is established.
Key words: off-centric tension, butt welds, tensile stress, convexity

Negoda Ye. N., Dzyuba A. A. � Strength analysis of the strapped welded constructions

Welded structure limiting state is calculated on the base of structural-mechanical fracture model of the ferrite-pearlitic steels and finite element method.

Bakhmatov P. V., Muraviov V. I., Melkostupov K. A. � Characteristic investigation of the high-duty aluminium alloy B95T2 friction welding with mixing

A possibility of friction welding with mixing for constructions from high-duty aluminium alloys is established by an example of the alloy B95. A modelling method of obtaining welded joint on a plasticine model is tested. Limiting temperature and its distribution character both in the model and in the operating tool at the aluminium alloy B95 are determined.
