Abstract

The structure of a typical control system for the wire-based electron-beam surfacing process, which is used today for the implementation of additive technologies, is considered, and the main regularities of the process are described. It is shown that the temperature of the underlying layer, which changes during surfacing, is a destabilizing factor affecting the pool temperature and the transverse dimensions of the formed layer. The necessity of using a feedback control system to stabilize the temperature of the deposited layer is substantiated and its technical implementation is described. The results of using the developed prototype of a temperature stabilizer based on a microcontroller are presented, and the fundamental possibility of ensuring the repeatability of the height of the deposited layer and eliminating the separation of the wire from the liquid pool during surfacing of a multilayer cylindrical contour made of 316L steel is shown.
