焊接气溶胶形成机理与焊接发尘量影响因素研究进展

焊接过程中产生的气溶胶影响作业环境和工作人员身体健康。总结了熔化极气体保护焊中焊接气溶胶的形成机理以及影响焊接发尘量的因素，并对每一种影响因素的研究现状和研究结论进行归纳，展望了未来研究焊接气溶胶的形成机理以及影响焊接发尘量的因素的方法和发展趋势。后期需要建立一个基于动态条件下的统一模型研究气溶胶的形成机理和多因素影响的发尘量变化规律，并结合高速摄像和图像处理技术，将研究方法从简单的实验观察提升到规律性的研究。

Research Progress on Formation Mechanism of Welding Aerosol and Influencing Factors of Welding Dust Emission

The aerosol produced during welding affects the working environment and the health of workers.In this paper, the formation mechanism of welding aerosols and the factors affecting the amount of welding dust are summarized, and the research status and conclusions of each influencing factor are summarized, and the methods and development trend of the formation mechanism of welding aerosols and the factors affecting the amount of welding dust are prospected.Late need to build a unified model based on dynamic conditions to study the formation mechanism of aerosol and many factors influence the amount of hair dust change rule, and combined with high-speed camera and image processing technology, the research methods from the simple experimental observation to regularity.
