目的-本文的目的是分析气体保护钨极氩弧焊（GTAW）过程中的声音特性，这是非常重要的，有效地监测焊接质量在未来通过使用从声音中提取的信息。设计/方法/途径-在实验中使用的硬件进行了说明。研究了焊接工艺参数（气体流量、焊接速度、焊接电流、弧长）对电弧声的影响及焊接声场的分布。最后，基于傅立叶变换和递推最小二乘法，研究了焊接功率与焊接声的关系，结果表明：焊接声压受气体流量、弧长和电流的影响很大，焊接声源服从偶极子模型;当焊接功率的三阶导数结合在一起时，可以更好地预测声音。独创性/价值-本文对焊接声源模型进行了新的认识，并详细分析了焊接噪声对焊接声源的影响。
Purpose – The purpose of this paper is to analyze the characteristics of sound during gas tungsten argon welding (GTAW), which is very important to effectively monitor the welding quality in future by using the information extracted from sound.Design/methodology/approach – The hardware used in the experiment is described. Then the paper researches the influence of welding techniques (gas flow, welding speed, welding current, and arc length) on arc sound and the distribution of the welding sound field. Finally, the relation between welding power and sound are studied based on Fourier transforms and recursive least square methods.Findings – The sound pressure is affected greatly by gas flow, arc length, and current; welding sound source obeys the dipole model; the sound can be better predicted when the three orders derivative of the welding power are combined together.Originality/value – This paper provides a new insight into welding sound resource model and a detailed analysis of the influence of the weldi...
