The influence of heat transfer on molten pool size and temperature during the additive metal wire deposition process is shown. A mathematical model based on an energy equation that considers latent heat during melting is proposed. The model also examines the temperature dependences of thermophysical properties and the results are presented graphically. The analysis of computer simulation results reveals a gradual increase in molten pool size during deposition of a hollow cylindrical shape due to the influence of reheating zones. The results of experimental studies (conducted on ELA-40I and AELTK-12 electron beam installations) that confirm the simulation results are presented. Both sets of results suggest the need for feedback in order to control the molten pool temperature. As such, the proposed model is used to conduct a study involving temperature feedback. The analysis of time dependences obtained via simulation shows the fundamental possibility of stabilizing the temperature at a desired point. Limitations and possible improvements to this method are explored.

显示了附加金属丝沉积过程中传热对熔池大小和温度的影响。提出了一种基于能量方程的数学模型，该模型考虑了熔化过程中的潜热。该模型还检查了热物理性质的温度依赖性，并以图形方式显示了结果。对计算机模拟结果的分析表明，在空心圆柱形状的沉积过程中，由于再热区的影响，熔池尺寸逐渐增加。给出了证实模拟结果的实验​​研究结果（在ELA-40I和AELTK-12电子束装置上进行）。两组结果都表明需要反馈以控制熔池温度。因此，建议的模型用于进行涉及温度反馈的研究。通过仿真获得的时间依赖性分析表明，将温度稳定在所需点的基本可能性。探索该方法的局限性和可能的​​改进。
