The paper provides a comparative experimental evaluation of effect of different factors on residual deformations in arc surfacing of thin steel plates. Effect of composition, structure state and part fixing method in surfacing with Sv-08A, PP-Np-25Kh5FMS and Sv-Kh19N18G6M3V2 wires on plates from St3 steel of 3×150×240 mm size were evaluated at different conditions of their fixing. It is experimentally determined that differences in physical properties and structural state of base and deposited metal have the highest effect on the level of residual deformations. The results obtained in this work can be used in development of technology of wear-resistant surfacing of thin sheet structures. 9 Ref., 2 Tabl., 4 Fig.
