Effect of Heat and Vibration Treatment on Cold Resistance and Structure of ER70-S6 Steel Obtained by Electric Arc Cladding 3D Printing

The effect of heat and vibration treatments on the structure and mechanical properties of experimental samples obtained from ER70-S6 welding wire by additive electric arc growing is considered. Based on the results of impact tests, the cold resistance of experimental samples was assessed. Using electron microscopy, the microstructure of the material was obtained and the grain size was calculated. It is shown that thermal and vibration treatments significantly increase the cold resistance of materials obtained by electric arc cladding. Replacement of heat treatment operations is possible by introducing the vibration treatment function of the weld pool into hybrid machining centers.
