Purpose - to study the control of the melting process of the metal during welding and allied processes, especially strip electrode welding, welding a metal plate with the action of a longitudinal magnetic field, the impact of the final welding stresses on the performance of structures, forced transfer of electrode metal on the parameters mode when the strip electrode surfacing quality of educational services Research methods - mathematical modeling, full-scale, laboratory model test methods, metallographic, X-ray analysis, hydrostatic weighing, high-speed filming, wear resistance at elevated temperatures, shock tests. The object of study - arc welding, welding, strip electrodes, the longitudinal and transverse magnetic field, the method of calculating the induction coupling strength of the coating performance of welded structures, anti-porosity, forced transfer of electrode metal, ensuring the quality of educational services. It is set that the melting action of arc depends on the angle of slope VAKH of source of feed. The maximal value of melting action and depth of the deposition provide the angle of slope VAKH of source about 5 мВ/А. Conducted calculations of the thermal fields at welding of ЗППР, that well coincide with experimental data. Powder-like electrodes are worked out with enhanceable wearproofness for deposition of aluminum pistons. Offered calculation methodology of description of the magnetic fields inductive the system from two electromagnets by means of design of magnetic-field the electrostatic field. Methodology allows to expect the level of induction of magnetic-field in the zone of roller at welding of ferromagnetic steels. Calculations of concentration of tension, arising up at renewal necks of working rollers of flatting mill by their banding showed that she did not exceed a norm. For reduction of tension it is necessary to create on butt-end surfaces to the bracer circular recesses. Research of feature of soldering of different types of metals in artificial gas environments and influence of them on the capacity of weldments. Influence of angle of slope of electrode ribbon is investigational in relation to the vector of speed of the deposition on appearance in the process of exploitation of cracks in the zone of ceiling of rollers, recommended optimal corners that provide the increase of cracking resistance. Improved methodology of educational process in vocational orientation activity, forming of terms of access to education, planning of reception on studies and adaptation of students of the first course to the terms of educational process in University.
