项目摘要

This SGER grant aims at developing a pilot system to achieve synergistic and stable deep penetration welding by combining a fiber laser and a plasma jet. The success of this pilot system heavily relies on a real-time plasma sensor and the integration of the fiber laser and the plasma jet. To develop this real-time plasma sensor, a high speed photography system will be integrated with a high performance computing system for image processing at a frame rate up to 200,000 fps. This high speed photography system allows the PIs to observe the oscillation of keyhole and plasma ejection in order to validate and refine the design of the new plasma sensor array. The observation also allows the validation of rigorous mathematical modeling of the laser/plasma-jet process currently under development. The key technology resides in synergistic energy deposition of a laser beam with moderate power and a plasma torch with a special nozzle design. The laser, with its much higher power density, will create the keyhole while a finely focused plasma jet from the plasma torch will provide additional energy deposition. The keyhole will be stabilized through active regulation of the plasma jet and the laser-induced plasma. The successful development of closed-loop deep penetration laser welding processes will be a breakthrough in this area. The request SGER grant will allow the PIs to prove the synergistic energy deposition concept as well as the inherent stability of the process, thus, establishing the foundation for a closed-loop welding system. Such a closed-loop system has not been attempted because the lack of real-time feedback sensors.The technology will render laser welding economically viable for a much larger range of industries. The US industry is in need of this kind of advanced technology to boost competitiveness in order to turn back the tide of off-shoring jobs by many major corporations. Further, US laser job shops (over 10,000) will see their service capability significantly increased by the availability of such a technology. Computationally, the project uses novel combination of numerical strategies. The work is being performed in an interdisciplinary group environment that integrates research with undergraduate and graduate students through both courses and projects.
这项SGER拨款旨在开发一个试点系统,通过结合光纤激光器和等离子体射流来实现协同和稳定的深熔焊接。该先导系统的成功在很大程度上依赖于实时等离子体传感器以及光纤激光器和等离子体射流的集成。为了开发这种实时等离子体传感器,高速摄影系统将与高性能计算系统集成,以高达200000 fps的帧率进行图像处理。这种高速摄影系统允许pi观察锁孔振荡和等离子体喷射,以验证和完善新的等离子体传感器阵列的设计。这一观测结果也验证了目前正在开发的激光/等离子体喷射过程的严格数学模型。其关键技术在于中等功率激光束与特殊喷嘴等离子体炬的协同能量沉积。具有更高功率密度的激光将产生锁孔,而来自等离子炬的精细聚焦等离子射流将提供额外的能量沉积。钥匙孔将通过等离子体射流和激光诱导等离子体的主动调节来稳定。闭环深熔激光焊接工艺的成功开发将是这一领域的一个突破。SGER授予的请求将允许pi证明协同能量沉积概念以及该过程的固有稳定性,从而为闭环焊接系统奠定基础。由于缺乏实时反馈传感器,这种闭环系统还没有被尝试过。这项技术将使激光焊接在更大范围的行业中具有经济可行性。美国工业需要这种先进的技术来提高竞争力,以扭转许多大公司外包工作的趋势。此外,美国激光车间(超过10,000)将看到他们的服务能力显着提高这种技术的可用性。在计算上,该项目使用了新颖的数值策略组合。这项工作是在一个跨学科的小组环境中进行的,通过课程和项目将本科生和研究生的研究结合起来。
