Local normalization of the weld made by electroslag welding

The accompanying local normalization of the seam made by electroslag welding (ESW) allows to bring the mechanical properties of the seam and the zone of thermal influence to the level of the base metal. The process of concomitant normalization proceeds at a temperature from 600 to 950 °C on average, in a hot mode with constant thermophysical properties of the heated metal. The distribution of the density of internal sources over the seam cross-section is considered in three approximations. An approximation is recommended with a smaller number of assumptions compared to others.
