Double-Sided Arc Welding

本课题的研究目标是建立一种基于双面弧焊（DSAW）的新型适用熔透增强技术，以提高熔透能力。这样，通过工件的焊接电流被认为增强了局部能量输入。工作范围涉及基础物理、新工艺开发和工艺控制问题。实验研究将强调对过程的基本理解，以开发实施的关键技术基础。这需要对电源-火炬-工作-火炬-电源的能量/材料回路和由此产生的热影响区有具体的了解。建模技术对于流程建模来说是最先进的。研究者包括一个计划，以教育研究生在基础科学的整合和工业应用的潜力。对工业的影响应该是显著的，一些行业致力于为这种新工艺在生产水平上的未来发展提供设备和工程支持。

9812981Zhang The objective of this research project is to establish a new applicable penetration enhancement technology based on double-sided arc welding (DSAW) to increase penetration capability. In this way, the welding current passing through the work is thought to enhance the localized energy input. The scope of work addresses basics physics, novel process development, and process control issues. The experimental study will emphasize the fundamental understanding of the process in order to develop key technological foundations for implementation. This requires specific understanding of the power supply-torch-work-torch-power supply energy /material loop and the resulting heat affected zone. The modeling techniques are state-of-the-art for the process modeling. The investigator includes a plan to educate graduate students in both the fundamental science integration and the potential for industrial applications. The impact on industry should be significant and several industries are committed to providing equipment and engineering support for the future development of this novel process at a production level.
