本文运用高速摄影技术、波形分析等手段,就各种类型焊条金属熔滴过渡形态进行了研究,初步总结和归纳了焊条金属熔滴过渡的基本规律,并提出焊条金属熔滴过渡形态划分为粗熔滴短路过渡、“附壁”过渡、喷射过渡和爆炸过渡四种主要类型,较系统地观察和分析了各种过渡形态的特点及其内在联系。文中着重焊条金属熔滴过渡形态对焊条工艺性能影响较为突出的电弧稳定性和飞溅形式两个方面做了一些分析和探讨。为提高焊条综合工艺性能,还就合理过渡形态表明了看法。
In this paper, by means of high-speed photography and waveform analysis, the metal droplet transition morphology of various types of welding electrodes is studied. The basic rules of the metal droplet transfer are summarized and summarized. The metal droplet transfer morphology is divided into coarse The droplet short-circuit transition, the “wall-attached” transition, the jet transition and the explosion transition. It systematically observed and analyzed the characteristics and internal relations of various transitional forms. This article focuses on the welding rod metal droplet transition morphology of the electrode more prominent impact on the arc performance of the arc stability and splash form some analysis and discussion. In order to improve the electrode comprehensive process performance, but also shows the reasonable transition morphology.
