This Grant Opportunities for Academic Liaison with Industry (GOALI) project will use a new machine vision sensing system designed with laser backlighting techniques to capture the transfer of metal droplets from a Gas Metal Arc welding system to controlled deposition in a 3-D geometry. The knowledge gained from these experiments will provide a better understanding of the physics of the droplet formation and the deposition mechanisms. It is expected that a high speed image-processing algorithm will be developed to extract key geometrical information from within this high temperature, difficult environment. The transfer of the metal droplets plays a fundamental role in determining the quality of the final product. Due to the strong coupling that exist among the welding parameters, the experimental work is designed in an attempt to isolate their effects upon the droplet formation and deposition. The new layered deposition method based upon this controlled droplet process has high potential for industrial applications, and industry commitment is demonstrated in this GOALI research project.

该资助学术与工业联络机会 (GOALI) 项目将使用采用激光背光技术设计的新型机器视觉传感系统，以捕获金属熔滴从气体金属电弧焊接系统到 3D 几何形状中的受控沉积的转移。从这些实验中获得的知识将有助于更好地理解液滴形成的物理原理和沉积机制。预计将开发出一种高速图像处理算法，以从这种高温、困难的环境中提取关键的几何信息。 金属熔滴的转移对于确定最终产品的质量起着重要作用。由于焊接参数之间存在强耦合，实验工作的目的是隔离它们对熔滴形成和沉积的影响。基于这种受控液滴过程的新型分层沉积方法具有很高的工业应用潜力，并且这个 GOALI 研究项目证明了行业的承诺。
