Abstract
The influence of methods of automatic arc surfacing on penetration of base metal, quality of formation and geometric sizes of deposited beads was investigated. In the experiments nine batches of flux-cored wires (25Kh5FMS type of deposited metal) of the diameter of 1.8; 2.4 and 2.8 mm for submerged arc, shielding gas and open arc surfacing were used. The surfacing was carried out in a wide range of modes: I_s = 150–450 A; U_s = 20–34 V at the same surfacing speed of 20 m/h. It was found that the greatest influence on formation of deposited beads is exerted by arc voltage. Moreover, the range of ΔU_T voltages, at which a good formation of deposited beads and absence of pores is provided, does not coincide during surfacing by different methods with wire of the same diameter. The results obtained in this work can be used for selecting the method of arc surfacing, surfacing modes, which ultimately meet the operating conditions and the requirements to the deposited metal for definite parts. These results will be also used in databases in the development of computer programs for robotized additive technologies of arc surfacing. 13 Ref., 1 Table, 6 Figures.
