SOME CHARACTERISTICS OF ELECTRON BEAM MELTING PROCESS
Journal Title: Proceedings in Manufacturing Systems - Year 2014, Vol 9, Issue 2
Abstract
The electron beam melting is a process applied in case of some electron beam machining methods. Essentially, the electron beam machining is based on the effects generated in the workpiece surface layers as a consequence of the penetration in this layer of electrons included in a high energy electron beam. For this reason, it is important to better know the characteristics of the melting processes developed in the workpiece material under the action of high energy electron beam. The method of systemic analysis was applied in order to highlight the factors able to exert influence on the output parameters specific to the electron beam melting process. A complete factorial experiment was thought and developed; by mathematical processing of experimental results, empirical models being determined. The analysis of empirical mathematical models and some graphical representations elaborated on the base of these empirical models allowed formulating some remarks concerning the variation of the weld depth and width at the variation of electron beam current intensity and speed of relative motion between electron beam and test piece.
