Abstract: TYPE 316 AUSTENITIC STAINLESS STEEL SUBMERGED ARC WELD DEPOSITED METAL, PRODUCED BY JOINING TWO HEAVY (50 MM) THICKNESS PLATES, WITH A MULTIPASS PROCEDURE AND USING TYPE 316L FILLER METAL, WAS CHARACTERIZED FROM BOTH A COMPOSITIONAL AND STRUCTURAL POINT OF VIEW (OPTICAL AND SCANNING ELECTRON MICROSCOPY OBSERVATION, ENERGY DISPERSIVE X-RAY ELEMENTAL ANALYSIS AND FERRITE CONTENT AND HARDNESS MEASUREMENTS). IMPORTANT FEATURES SUCH AS COLUMNAR GRAIN MACROSTRUCTURE MAINLY CELLULAR-DENDRITIC AND A DUPLEX MICROSTRUCTURE WERE OBSERVED ACCORDING TO THE OCCURRENCE OF A DENDRITIC-AUSTENITIC WELD-POOL SOLIDIFICATION MODE FOLLOWED BY A SOLID-STATE DELTA-GAMMA TRANSFORMATION. THE WELD DEPOSITED METAL WAS CHARACTERIZED ALONG THE THICKNESS BY SIGNIFICANT VARIATIONS IN COMPOSITION AND FERRITE MORPHOLOGY, DISTRIBUTION AND THE THERMAL CYCLES EXPERIENCED BY EACH PASS DURING SUBSEQUENT PASSES.
