ELECTRON BEAM WELDING METHOD IN THE MAGNETIC FIELD
https://doi.org/10.15518/isjaee.2015.21.030
Abstract
The paper presents the method of uphill electron beam welding in magnetic field for thick parts joining with a through-penetration without usage of runoff blocks in the root. Moreover, it shows the possibility of high-quality weld obtaining without vacuum cavities by reducing the hydrostatic pressure forces applied to the molten metal in the weld pool and the increase of surface tension forces. Experiment technique and EBW conditions of 40-mm thick welds of AISI 316 L(N) steel with the assessment of their quality are described. It is experimentally approved that usage of the proposed EBW method with the formation of the curve shaped channel penetration enhances the range of process conditions providing a stable quality of welded joints.
