The purpose of the work is to develop and improve welding, surfacing and spraying technologies in order to increase process productivity, improve quality and ensure high performance of welded and welded products. Research methods - computational and software data processing, experimental research. The parameters of the transverse magnetic field for efficient mixing of the melt during arc surfacing are determined. It is established that with increasing induction By POMP (from 25 mT to 100 mT) the values of frequency f POMP increase. Thus, for complete mixing of the liquid metal (along the entire length of the tail of the bath Lxv) requires a pump frequency of about 1 ... 1.5 Hz at the level of induction Bz = 25 mT. If you increase the induction By PUMP to By = 100 mT, the optimal frequency values are in the range of 1.7 ... 3 Hz. These data are recommended for use when performing electric arc surfacing with wire under flux. The basic principles of designing the equipment of stands of automatic welding of sheet beam designs are developed. The dependence of the choice of options in each case on the serial production and other conditions is established. Powder electrodes have been developed to solve problems related to the deposition of aluminum alloy parts. Parameters and requirements for electrodes are defined. Calculation dependences are got for the estimation of the напруженного state of the welded butt connections. Studies of the process of heat and mass transfer of the electrode metal with the use of mechanical control of the electrode, which allow the use of resource- and energy-efficient technology of restoration of working surfaces.
