Arc-Voltage and-Current Transients during Metal Transfer

Abstract

The not-so-simple mechanisms of metal transfer constitute a major area of interest to researchers in the field of physics of arc welding. A thorough understanding of the mechanisms involving the metal transfer can help the welding engineers to a large extent in controlling the physico-metallurgical characteristics of the weldment and in designing suitable welding power sources. A great deal of research has already been conducted on the theory of metal transfer in arc welding and the available literature is quite extensive. However, the continuing research activities throughout the world is only a pointer to the very complicated nature of the problem requiring a large number of parameters to be controlled.
