摘　　要：本研究对圆盘零件多圈焊接过程进行模拟,并通过选取特征点来观察焊接过程中的温度演变规律。利用MARC对圆盘零件进行三圈的焊接模拟。焊接过程中,观察关键区域的温度演变,并通过选取特征点来实时监测温度的变化。通过该过程,得以深入了解焊接热源的分布、传热路径和热效应,更好地理解圆盘零件多圈焊接过程中的温度变化规律,为未来焊接工艺优化提供理论参考。In this study,the finite element analysis software MARC is used to simulate the multi-lap welding process of the disc parts and to observe the temperature evolution pattern during the welding process by se-lecting the characteristic points.The welding simulation of the disc part was carried out for three turns using MARC.During the welding process,we observed the temperature evolution in critical areas and monitored the temperature changes in real time by selecting feature points.This process allowed us to gain insight into the distribution of welding heat sources,heat transfer paths and thermal effects.A better understanding of the temperature change rules during the multi-ring welding of disc parts provides a substantial reference for fu-ture welding process optimisation.
