摘要

在提高堆焊性能和堆焊工艺的各种常用方法中，磁场的介入可能是一种有效的方法。本文通过对磁场对电弧焊影响的实验研究，对磁场对电弧焊的影响进行了系统的探讨。在处理堆焊质量方面也可以采用类似的方法。对金属薄板在外加磁场作用下的电弧焊和堆焊进行了试验研究。提出了磁加载在熔池前部的应用。焊接电弧过程中的外加磁场通过电磁力在与电弧垂直的平面上引起电弧的形变。外加磁场范围为20-30mT，频率范围为4-6Hz。在筛选凝固机理时考虑了铸造性能和冶金性能。本文对团簇机理进行了详细讨论，分析了熔池中金属凝固的影响。与合金相比，金属表面处理技术的改进得到了强调。收稿日期:2023年4月9日修稿日期:2023年6月12日收稿日期:2023年6月25日

EFFECT OF MAGNETIC FIELDS ON ELECTRIC ARC WELDING AND SURFACING PERFORMANCE

Among the various popular methods to enhance performance of electric arc welding as well as surfacing process, involvement of magnetic fields may provide an effective way. A systematic approach is made in this paper by focusing on experimental work of the influence of magnetic field on the electric arc welding. Similar approach can be extended in handling surfacing quality. Experimental tests were carried with respect to electric arc welding and surfacing of a metal sheet under the impact of external magnetic field. The application of magnetic loading was provided in front part of the weld pool. The applied magnetic field during welding arc process leads to delectation in the arc via electromagnetic force, which acts in the plane normal to the field. The applied magnetic field was kept in the range of 20-30mT and a frequency range from 4-6Hz. The foundry and metallurgy properties were considered in shortlisting solidification mechanism. A detailed discussion is reported with cluster mechanism, wherein impact of metal solidification in weld pool is analyzed. Better surfacing techniques for metals are highlighted with respect to alloys. Received: April 9, 2023Revised: June 12, 2023Accepted: June 25, 2023

期刊介绍： The JP Journal of Heat and Mass Transfer publishes peer-reviewed articles in heat and mass transfer which enriches basic ideas in this field and provides applicable tools to its users. Articles both theoretical and experimental in nature covering different aspects in the area of heat and mass transfer such as heat transfer in phase change phenomena, machinery and welding operations, porous media and turbulence are considered. Priority is given to those which employ or generate fundamental techniques useful to promote applications in different disciplines of engineering, electronics, communication systems, environmental sciences and climatology. Because a combination of two or more different technologies in a single device may result into a significant development, the journal extends its scope to include papers with the utility value in electronics and communication system. In this spirit, we are devoting certain number of issues to ‘Mechanical Systems and ICT – Convergence’. Survey articles dealing with certain issues in the context of current developments in heat and mass transfer together with their applications in interdisciplinary topics are also entertained.
