SCIENTIFIC-TECHNICAL SECTION

Steklov O. I., Pavlyuk S. K., Lupachev A. V. � Behavior of welded and soldered joints of the galvanized steel in the corrosive environment

Conceded the behavior of compounds in a corrosive environment galvanized steel made by arc welding and soldering without prior removal of coating with the use of welding materials based on iron, copper, aluminum and zinc. Determined by the topography of the electrode potentials and galvanic currents on the surface of the compounds covered by a thin layer of electrolyte. Set maximum width of the damaged coating relative to the joint, providing the effect of anodic protection. Evaluated the corrosion resistance of connections.
Key words: welding, galvanized steels, corrosion resistance

Rozinov A. Ya., Shatilov V. A., Logunov V. V. � Determination of the stress state and power of erection joints of thin-sheet constructions at the change of succession of assemblage and welding

Research results of stress arising in the trimming and girders of the set of erection joints of constructions which were obtained at the traditional and changed succession of realization of the assembly-welding work are covered.
Key words: erection joints, state of stress, assemblage, welding, cyclical extension, cyclical bend

Trushnikov D. N. � Application of the wavelet analysis of signals of the secondary current for research and control of the electron-beam welding

Research results of signals of the secondary current in the plasma at the electron-beam welding are covered by means of the wavelet analysis. By means of the discrete wavelet transform it is established that the energy of the signal at the electron-beam welding of 2 to 12 kW in power in the high-frequency area is generally concentrated in the frequency range of 8 to 63 kHz. The dependence of coefficients of detail on the unit power of welding is researched.
Key words: electron-beam welding, wavelet analysis, secondary-emission signals, control of weld formation

Tsumarev Yu. A., Kulikov Yu. P., Radchenko A. A. � Suggestions for changing standards into structural elements of welded joints

Analysis of the basic provisions of GOST 14771�76 and 5264�80 concerning the consumption of resources which are necessary for formation of welded joints is carried out. It is showed that some provisions of given standards do not correspond well to the principle of minimization of the consumption of resources. Suggestions for correction of the provisions of GOST 14771�76 and 5264�80 are introduced.
Key words: welded joints, consumption of resources, GOST
