Abstract

Abstract When metals are joined by welding, the strength and other qualities of the products vary greatly depending on the welding conditions. In this paper, authors focus on ring mash welding used for powertrain components that transmit engine drive. This welding is required to be strong enough to withstand large loads. However, it is difficult to find appropriate welding conditions because there are many welding parameters, such as the welding current, applied force and shapes to be welded. Moreover, since the welding point is inside the base metal, it is difficult to understand the phenomena and the deformation process during welding. Therefore, it takes much time to determine welding conditions through repeated experiments and to develop and improve the welding process. Since the numerical analysis of welding phenomena is supported by theoretical analysis and plays an important role in quality assurance of welded products, the authors tried to make the numerical model using the fundamental experimental results. In this study, the visualization of the phenomena and the relationship between the welding current and the applied force made clear using the numerical simulation. The effect of welding conditions on the welding results when they are varied.

环坯焊接数值模型的建立

当金属通过焊接连接时，产品的强度和其他质量因焊接条件的不同而有很大差异。本文主要对传动系统部件的环焊进行了研究。这种焊接要求足够坚固，能承受大的载荷。然而，由于存在许多焊接参数，如焊接电流、施加的力和要焊接的形状，因此很难找到合适的焊接条件。此外，由于焊接点在母材内部，焊接过程中的现象和变形过程难以理解。因此，通过反复试验确定焊接条件，开发和改进焊接工艺需要花费大量的时间。由于焊接现象的数值分析有理论分析的支持，对焊接产品的质量保证起着重要的作用，作者试图利用基本的实验结果建立数值模型。在本研究中，通过数值模拟明确了现象的可视化以及焊接电流与施加力之间的关系。研究了不同焊接条件对焊接效果的影响。
