Abstract
The effect of the rotation of an arc on the weld formation in welding 1565chM alloy sheets is studied. The arc rotation is shown to induce controlled low-frequency perturbations, which depend on the tungsten electrode rotation frequency, in a weldpool. Periodic changes in the value and direction of temperature gradient favor misorientation and refining of the weld structure. The arc rotation in welding intensifies the release of gas bubbles and oxide inclusions from a weld.
