Stabilization of Root Parameters for Shielded Arc Welding

Abstract

The study revealed that the application of flux paste to the back side of the welded joint during welding of low-alloyed steels provides control over the sizes of the root and its defect-free formation. It was found that the back bead height of the root welded with flux paste is 1.5 to 3 times less than that of the root welded with the same welding variables without flux paste.
