摘要： 基于对焊接热影响区性能研究的必要性,以Windows XP系统为背景,应用LabVIEW 8.2和STEP 7进行编程,自主研发出焊接热循环计算机软件,该软件已成功嵌入东北大学轧制技术及连轧自动化国家重点实验室自主研发的MMS系列热力模拟实验机.利用该软件能够实现焊接热循环过程的在线模拟,定量地反映与描述影响各热循环参数的主要因素及其相互关系.通过采集焊接热循环曲线和试样的组织形貌分析,完成峰值温度等参数对焊接热影响区组织性能影响的实验研究,实现焊接热循环过程在线模拟的应用价值.

Abstract: A software for welding heat cycle simulation was developed based on the Windows XP system. The software was programmed by LabVIEW 8.2 and STEP 7 and was embedded in the MMS series thermo-mechanical simulator which developed by State Key Laboratory of Rolling and Automation, Northeastern University. The results showed that the online simulation of welding heat cycle process can be achieved by the software, which can reflect and describe quantitatively the main influencing factors of heat cycle and the correlation among them. Through the acquisition of welding heat cycle curve and the analysis of the sample morphology, the experimental study of heat affected zone affected by the peak temperature, etc. can be completed, and the application of online simulation of welding heat cycle process can be realized.
