Golikov N. I., Sidorov M. M. � Residual welding voltage redistribution at ultrasonic percussive treatment of the pipe joint welds

It is investigated distributions of residual welding pressure of welded connection of a joint of a pipe in diameter of 720 mm, thickness of a wall of 8 mm, made of steel mark 13�1�� after welding works and influence of ultrasonic shock processing on redistributions of these pressure.
Key words: residual welding pressure, ultrasonic shock processing, manual arc welding, automatic welding under a gumboil, pipes

Musatov V. A., Shtrikman M. M., Yegorov V. N., Abramova Ye. A. � Bearing capacity evaluation of a test bed welded truss construction

Calculation results of a welded truss construction at test bed static and dynamic loading simulating force at in-flight rocket lateral module separation are covered. Static test results of a truss standard welded joint are obtained and compared with the calculated data.
Key words: welded construction, truss, test bed, mode of deformation, strength, testing

Tokmin A. M., Svechnikova L. A., Masansky O. A. � Characteristic interrelation between inductive surfacing and pad structure and properties

Analyzed the processes occurring during melting and crystallization of the deposited powder sormayta, factors influencing the formation of physical and mechanical properties of the product as well as an attempt to formalize the functional relationships using regression analysis. Conducted metallographic studies and power dispersive analysis of the transition zone and deposited layer. Establish a pattern of change of wear on the rate of deposition, as well as hardness and thickness of the deposited layer. It is shown that for high wear resistance of deposited layers is necessary to use a multilayer deposition.

The article contains high frequency AC welder researches results. Power part of such a welder, a lightweight way of arc ignition and loading parameters are described. Welding microsections pictures show the quality of welded joints.
Key words: AC welder, alternating and direct current, welded joints, quality

Nikitin S. V., Bardin A. I., Biryukov A. P., Golovanchikov A. A., Koverguin P. V. � A Forsage 161 inverter welding machine: a novelty in welding

Technical data, major functions and ranges of application of new single-phase welding set Forsage 161 for manual arc welding by covered electrodes as of 1,6�4,0 mm in diameter are described.
Key words: manual arc welding, inverter welding machine, output current, volt-ampere

Potapov N. N., Kadigrobov I. A., Pen�kov V. B. � Gas saturation of the added metal at welding by basic-covered electrodes

It is shown that it is possible to improve significantly physical-and-chemical air protection of the added metal at welding by basic-covered electrodes by introducing thermally less stable fluorides into the coating composition in addition to CaF2. Their quantity optimization is determined not only by metallurgical but also by welding processing properties of electrodes.
Key words: electrode coating, added metal, metal gassing, fluorides, electrode coating ingredients

Sidorov V. P., Melzitdinova A. V., Reznikova I. V. � Spot diameter calculation to set contact welding conditions

Analysis of GOSTs and MIS-data by approximation allowed obtaining dependencies determining minimal diameter and spot nuclear area of section for every thickness of the welded elements. It is established that section fracture stress depend insignificantly on the thickness of welded elements.
Key words: resistance-spot welding, GOST, MIS, welding spot area of section, nuclear diameter, approximation, fracture stress, thickness of welded elements

Volkov S. S. � Brush componentry ultrasonic welding schedule

It is established that welding rate of brush-type elements increases when critical parameters of the welding conditions are increasing. Double-faced ultrasonic weld with seam melt formation into profile thickening fit for the brush holder groove is suggested. It is shown that fibre tear-out force out of the brush is higher at the double-faced brush welding than that at the single-faced one. This indicates that brush double-faced welding results show great stability.
Key words: ultrasonic welding, brush componentry, mode data, fibre tear-out force
