摘要：

The effects of electromagnetic pressure, resistance heat and rotating arc on process properties and micro properties in submerged arc surfacing using cable-type welding wire are analyzed. The electromagnetic pressure of cable-type welding wire submerged arc surfacing induced by seven welding wires is small than that of traditional single-wire submerged arc sufacing, resulting in the average decrease of the dilution rate by 33%; the resistance heat of the wire extension of the cable-type welding wire submerged arc surfacing is larger, resulting in an average increase of the deposition rate by 40%; the strong stirring effect of the cable-type welding wire submerged arc surfacing induced by the rotating arc gives rise to a finer and more uniform microstructure and larger hardness in the surfacing layer.
