Makhnenko V.I., Kvasnitsky V.V. and Ermolaev G.V. Effect of physical-mechanical properties of the materials joined and geometry of the parts on distribution of stresses during diffusion bonding in vacuum | 2 |
|
The method of computer modelling based on FEM was used to study the stress-strain state of cylindrical parts in diffusion bonding. It is shown that the complex stressed state with a non-uniform distribution of stresses is formed over the surface of a bond in joining even simple parts from dissimilar materials. It is established that thermal cycling is indicated to localise plastic strains within the bond zone in joints with different values of linear temperature expansion coefficient. |
Zorin I.V., Sokolov G.N., Artemiev A.A. and Lysak V.I. Electroslag cladding of end surfaces of parts by using slag pool double-loop power circuit | 9 |
|
Relationship was established between electrical and technological parameters of electroslag cladding conducted in a current-conducting mould by using a non-consumable hollow electrode, which allows control of the process of deposition of a multi-component metal with the gÂ-Ni3Al aluminide based matrix on the end surfaces of 25-90 mm diameter parts. It is shown that with a double-loop DC circuit powering the slag pool the processes running in the hollow electrodeÄworkpiece cladding circuit have a dominant influence on heat released in the pool. |
Golovko V.V. and Grabin V.F. Effect of alloying of high-strength weld metal with titanium on its structure and properties | 13 |
|
It is suggested that an integrated parameter, which allows for the level of alloying of solid solution with manganese, silicon, titanium and aluminium, as well as the content of titanium oxides in inclusions located in the bulk of ferrite grains, should be used to evaluate the effect of alloying of metal of the submerged-arc welds on their mechanical properties. |

|
The method of X-ray diffraction was used to study the granulated solid and molten welding fluxes of the grades of AN-67 type. Presence of crystalline phases in some of them is indicative of violation of the flux manufacturing process and the resultant deterioration of their quality (in complete compliance with the specification requirements). |

Dragan S.V. and Yaros Yu.A. Ensuring the stability of submerged-arc welding process at low current density | 26 |
|
The paper deals with the influence of energy parameters of «arc-power source» system at a combined volt-ampere characteristic of the power source and constant electrode wire feed rate on the stability of the welding process under the impact of disturbances along the arc length. |
Gedrovich A.I., Tkachenko S.A. and Kalenskaya A.V. Selection of wire for mechanized arc welding of similar and dissimilar joints of 10Kh13G18D steel | 30 |
|
Schaeffler structural diagram was used to substantiate selection of weld metal alloying and wire for gas-electric welding of similar and dissimilar joints on 10Kh13G18D steel. The rationality of applying Sv-08Kh20N9G7T welding wire was experimentally confirmed. |
Fomichyov S.K., Lopatkin I.E., Lopatkina K.G. and VasilenkoE.I. Remote training model of bachalor-welder | 32 |
|
The model is suggested for training of a bachelor-welder on the basis of a package of applied programs «Navigator», which ensures possibility of remote training in welding and relative technologies. |
