Temperature Field Simulation and the Effect on the Substrate During Wire Arc Additive Manufacturing of 316L
In order to investigate the temperature evolution law and the influence on the substrate during the wire arc additive manufacturing process, this paper establishes a three-dimensional transient simulation model based on the finite element method and carries out the simulation of the temperature field in the wire arc additive manufacturing process; the temperature of the additive process is measured by the thermal imager, and the simulation results are compared with the actual measurement results. The results show that: the simulation results and test results match well and verify the accuracy of the model; during the wire arc additive manufacturing process, the heat accumulation phenomenon increases in the high temperature region; the first four layers in the stacking process have a large thermal impact on the substrate; the sensitized depth of the heat affected zone of the substrate is about 6 mm below the substrate.
