Korchaguin P. V., Kazakov Yu. V., Potekhin V. P. — Thermodeformative processes at continuous arc welding of the parts of different thickness

Featheredge stability conditions are spesified at through-penetration argon-continuous arc lap welding of the parts with great difference in thickness. A mathemetical model of the temperature field at through-penetration welding of a featheredge using a phenomenon of arc anode spot lag from the electrode axis is suggested.
Key words: continuous arc welding, through penetration, mathematical model, stability

Zubarev V. Yu., Kolomensky B. A., Kolomensky A. B. — Effect of the welding conditions on the impact strength of the titanium welding joints

Effect of the welding conditions and annealing on the impact strength of different heat-affected areas of the titanium welded joints is studied. Impact strength maximum is established in the range of 350—550 °C, in practice that coincides with the temperature peaks for short-time strength and fatigue life.
Key words: titanium alloy, welding, annealing, delayed fracture, fatigue crack life

Goncharov A. L. — Thermal e. m. f. study of steels and alloys of different structural classes at electron-beam welding

Research results of the thermoelectric properties of steels of different structural classes are covered, as well as of the alloys on the bases of nickel and cobalt. Thermal dependencies are obtained for the absolute thermal e. m. f. coefficient of materials.
Key words: thermal e. m. f., thermal e. m. f. coefficient, steel, alloy, procedure

Balagansky A. Yu., Ivanaysky V. V. — Modelling of the induction deposit welding of the components of variable cross-section

A model is suggested which allows for estimating operating rate, pad quality and obtaining information on energy consumption from an external power source and its release in the heated components, and therefore selecting controllable parameters to ensure optimum values of the process output characteristic.
Key words: modelling, calculation, process, components, variable section, induction welding

Tarasov A. N., Murashko V. M., Gopanchook V. V. — New plasma-arc coating of the electric thrusters magnetic conductors components
