Abstract
Metallurgical methods intended to decrease the sulphur content of the weld metal in flux-cored wire welding were studied. The possibility of decreasing the content of sulphur in metal by using magnesium- and calcium-containing master alloys is shown. The prospects for improvement of mechanical properties of welded joints through decreasing the sulphur content of the deposited metal are considered.
