Abstract
An experimental platform was built for simultaneous acquisition of the input and output electrical signals as well as droplet transfer images during the welding process. By analyzing the rectifier circuit of the welder, the calculation method of the instantaneous input power, the instantaneous input power envelope, and the input pulsating energy (EP) were given. The input pulsating energy was found to better characterize the dynamical change process at the output terminal upon comparison. Then, the short circuiting transfer, free transfer and mixed transfer patterns were obtained by varying the wire feeding speed and the given voltage. Based on the standard variance (SD) and coefficient of variation of the input pulsating energy (v(Ep)), the parameter variations in different transition patterns and the stability of the transition process were compared and analyzed. The results reveal that the v(Ep) was greater than 18% for short circuiting transfer and less than 9% for free transfer.
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
