Simulation of electromagnetic and thermal processes during induction heating of pipelines in Elcut 5.1

Abstract

Abstract The article discusses the issues of modeling induction heating in the process of induction brazing of pipelines in a protective gas environment. Elcut 5.1 software product is used for modeling. The modeling of the following physical characteristics of the induction heating process is carried out: the electromagnetic field formed by the inductor, the distribution of eddy currents over the elements of the pipe being welded, the temperature distribution. On the basis of the developed simulation models, the influence of the position of the pipeline system assembly in the inductor window and the influence of the frequency of the current generated by the generator on the efficiency of the induction heating process are evaluated. The results obtained in the course of the study make it possible to efficiently adjust the technological parameters of the process of induction brazing of pipelines in protective environments and, accordingly, to improve the quality of the formed permanent joints.
