Matviyenko V. N., Leschinsky L. K., Mazur V. A. � Parent material heating and melting at compound strip-electrode flux surfacing

The results of the mathematical model of heat propagation when using submerged arc surfacing process with composite strip electrode have been presented. The model is designed upon solving the differential equation of heat conduction. Calculations and necessary graphs are made using the package MSC.Patran. The data in computational and experimental studies of the influence of geometry of the composite strip electrode on the shape and size of the weld pool, as well as non-uniformity of depth penetration is acquired. The calculated and experimental data are in agreement.
Key words: heat propagation, mathematical model, design procedure, submerged arc surfacing, composite strip electrode, central and lateral strips, angle of rotation, weld pool, depth and non-uniformity of penetration

Razmyshlyayev A. D., Mironova M. V., Yarmonov S. V., Vydmysh P. A. � Flow rate in the bath at arc surfacing in the transverse magnetic field

With regard to wire arc surfacing physical simulation shows that induced by constant transversemagnetic field the velocity of the liquid metal flow, pointed to the tail of the bath, increases with the current and the transverse component of the magnetic field induction. It is established that flow distribution is determined by the nature of the components� distribution of current density, extending out in the liquid metal of the weld pool. The obtained data can be used when determining the optimum frequency of the transverse magnetic field to control the size of the melting zone and the crystallization process of the metal of the weld pool during arc surfacing and welding.
Key words: arc surfacing, transverse magnetic field induction, flow rate

Pirinen M., Martikainen Yu., Ivanov S. Yu., Karkhin V. A. � Microstructure comparative analysis of the metal in the heat-affected area at high-strength steel welding

Welding of the joints 8 mm thick from high-strength steels obtained by the method of quenching and tempering, and thermomechanical rolling with accelerated cooling is considered. It is shown that at the identical strength of steels (821�835 MPa) HAZ microstructure is significantly different at the same welding conditions. Hardness distribution in all zones of the joint is given. It is established that weakened area in HAZ of the steel, obtained by thermomechanical rolling with accelerated cooling, is wider than in the steel obtained by the method of quenching and tempering; the difference makes 5 mm at two-pass arc welding.
