Abstract: Gas metal arc welding(GMAW) with cabletype wire is an innovative welding method which provided prominent advantages of high efficiency and low power consumption.Untill now,it has rare report on the welding residual stress of the new welding method.In the present study,the heat source model based on the welding seam profile is adopted to efficiently simulate the weding tempature field,and it is validated by comparison of simulated temperature field and experimental welding seam profile of bead-on-plate welding through GMAW with single wire.In addition,the simulated residual stress results are compared with the experimental ones on the top surface obtained by the hole drilling method.The investigated results show that the heat source model based on the weld seam profile is suitable for efficient temperature field simulation of GMAW with cable-type wire;on the top surface within the welding line and adjacent region,the residual stress distribution and magnitude of GMAW with cable-type wire are almost identical to those of submerged arc welding(SAW) under the same welding specifications,however,in the region far from the welding line,the amplitude of longitudinal compressive residual stress induced by GMAW with cable-type wire is larger than that induced by SAW.
