摘要

本文采用有限差分法(FDM)建立了移动热源模型(高斯分布)下，焊接参数对埋弧焊过程温度变化的影响的数值模型。实验结果表明，该方法与实验结果吻合较好。建立了模拟峰值温度的瞬态热数学模型。最后，在数值计算结果的基础上，研究了不同焊接参数(焊接速度、热输入和板厚)对温度分布的影响。结果表明，所有这些参数对温度分布都起着至关重要的作用。

A study of parametric effects on thermal profile of submerged arc welding process

In this study, a Numerical model is carried out to study the effect of welding parameters on the temperature variations in Submerged Arc Welding process (SAW) with moving heat source model (Gaussian distribution) by using finite difference method (FDM). The proposed method is validated from the experimental results and found is in good agreement with results obtained by experimental. The mathematical model of transient thermal is also recognized to simulate Peak temperature. Finally Parametric effects on temperature profiles based on numerical results, are carried out for different weld parameters including welding speed, heat input, and plate thickness. It has been shown that all those parameters are playing an essential role in affecting the temperature distribution.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
