一、前言温度是焊接工艺中可用来解释大量物理、化学和冶金过程的因素。利用温度场的数值和动力学可解释焊接过程中焊接参数的综合影响,因此,它们是使焊接工艺最佳化的基础[1—6]。
I. INTRODUCTION Temperature is a factor that can be used to explain a large number of physical, chemical and metallurgical processes in welding processes. The use of temperature field values and kinetics can account for the combined effects of welding parameters during welding and are therefore the basis for optimizing the welding process [1-6].
