熔化极气体保护焊发尘率研究进展

A review of fume formation rate in gas metal arc welding

焊接发尘率作为表征焊接烟尘特性的主要指标,是对焊接烟尘展开定量研究和进行数值模拟必不可少的依据,也是优化工艺参数实现对焊接烟尘控制,进而研制低尘焊接材料的研究基础。从焊接烟尘采集测量方法、焊接发尘率的影响因素和焊接发尘率的模型预测三个方面综述了国内外对GMAW焊接发尘率研究的重点及进展。

Fume formation rate is a major index for welding fume,it is the essential data for quantitative research and numerical simulation of welding fume,and is the basis for the related researches of the welding fume controlling by optimizing process parameters and developing the welding materials with low fume. The focus and progress of research on fume formation rate in GMAW at home and abroad were reviewed,which was summarized from three aspects of the collection methods of welding fumes,the influencing factor of fume formation rate and the prediction model of fume formation rate.
