Abstract

The orthogonal test of plate surfacing was carried out by CMT Cycle Step welding process. The effects of the wire feeding speed, welding speed, CMT cycles, pause time interval on the fish-scal texture and forming size of weld surface were studied. The regression models of the process parameters on the step size (S) of fish-scale texture, weld width B and overlay thickness h were established. The results show that with the increase of the welding speed, CMT cycles, and pause time interval, the fish-scale step size (S) on the weld surface increases gradually. Properly reducing the welding speed and pause time interva can effectively reduce the height difference of weld surface Δh, and improve weld surface forming quality. With the increase of the wire feeding speed and CMT cycles, weld width B and overlay thickness h gradually increase; With the increase of the welding speed, weld width B and overlay thickness h gradually decrease. According to the theoretical analysis and regression analysis, the regression equations with high accuracy were obtained, which provided a theoretical basis for predicting the weld formation and optimizing the welding process parameters.
