Effect of hydrostatic pressure on arc stability in underwater welding (Review)

Yu.Ya. Gretsky, S.Yu. Maksimov

E.O. Paton Electric Welding Institute of the NASU 11 Kazymyr Malevych Str., 03150, Kyiv, Ukraine.

Abstract
The problem of ensuring stability of the arc burning in water under conditions of high ambient hydrostatic pressure is considered. Current notions of causes of instability of the arc discharge are presented. Input principles are formulated for arrangement of studies to be conducted under the above conditions to solve the problem of expansion of technological capabilities of the method of mechanised underwater flux-cored wire welding developed by the E.O.Paton Electric Welding Institute
Keywords: underwater welding, hydrostatic pressure, arcing, process stability
