AGGLOMERATED WELDING FLUX AND SUBMERGED ARC WELDING PROCESS OF AUSTENITIC STAINLESS STEELS USING SAID FLUX

摘要

The invention relates to agglomerated welding flux comprising, expressed in %byweight of flux : 25 to 35% MgO, 20 to 28% CaF2, 15 to 22% A1203,12 to 17%SiO2, and0,2 to 0,4% carbon (% by weight), said carbon being introduced using at leastone metalliccompound contained in the flux. The invention also relates to a process forthe submerged-arc welding of at least one workpiece made of austenitic stainless steel usingsaid flux andto a welded joint comprising 17 to 20 % Cr, 5 to 8,5% Mn, and 14 to 18% Nithat can beobtained using said process.
