Abstract
The results of studies conducted in a special chamber to simulate deep-water flux-cored wire welding conditions are given. The efficiency of introducing activating additions to the wire composition to stabilize the arc operating at high depths is shown.
Keywords: underwater welding, flux-cored wire, arc burning, hydrostatic pressure, stability of process, activating additions
