Abstract

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.

参数对埋弧焊热分布的影响研究

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。

期刊介绍： TJPRC: Journal of Naval Architecture and Marine Engineering (JNAME) is a peer reviewed journal and it provides a forum for engineers and scientists from a wide range of disciplines to present and discuss various phenomena in the utilization and preservation of ocean environment. Without being limited by the traditional categorization, it is encouraged to present advanced technology development and scientific research, as long as they are aimed for more and better human engagement with ocean environment. Topics include, but not limited to: marine hydrodynamics; structural mechanics; marine propulsion system; design methodology & practice; production technology; system dynamics & control; marine equipment technology; materials science; under-water acoustics; satellite observations; and information technology related to ship and marine systems; ocean energy systems; marine environmental engineering; maritime safety engineering; polar & arctic engineering; coastal & port engineering; aqua-cultural engineering; sub-sea engineering; and specialized water-craft engineering. International Journal of Naval Architecture and Ocean Engineering is published quarterly by the Society of Naval Architects of Korea. In addition to original, full-length, refereed papers, review articles by leading authorities and articulated technical discussions of highly technical interest are also published.
