Volume: 330 CCIS
Pages: 436 - 441

Hot corrosion of Gas Tungsten Arc Welded (GTAW) AISI 304 and AISI 4140 dissimilar weldment exposed in air as well as molten salt environment of Na2SO4-60%V2O5 and K2SO4-60% NaCl are discussed. Weight gain studies were done for composite specimens containing both weld metal and heat-affected zone. The results indicated that the specimens were more corroded in molten salt environment as compared to air oxidation. Also weld interface of the samples showed more attack than base metals.
