  • Spray Transfer - an overview | ScienceDirect Topics

    Spray transfer takes place with higher currents and voltages. As the current increases there is an increased flow of droplets across the arc and the diameter of the droplets become smaller. The transfer therefore takes place in the form of a fine spray, giving a high deposition rate coupled with deep penetration and a large
