Abstract
The buried arc phenomenom is conventionally known as one of arc phenomena in gas shielded arc welding in which an arc is generated with the wire tip position being deeper than the molten metal surface.Since heat input by the arc is applied to a deeper portion of the base material than the usual arc phenomenom,very deep penetration can be obtained.
In this article welding system based on buried arc called " D-arc " is presented with results of application on different weld joint types.
Keywords
buried arc; deep penetration; " D-Arc "; stabilization
