<p>A dissimilar weld joint is commonly used in various engineering applications, such as petrochemical, oil, gas, nuclear industries and power generation. Mostly dissimilar weld joints offer an excellent combination of attractive properties, such as strength, hardness and corrosion resistance at lower costs. In the present study, dissimilar welded joints of 316L austenitic stainless steel (ASS) and 410 martensitic stainless steel (MSS) were investigated using both pulsed tungsten inert gas (PTIG) and gas tungsten arc welding (GTAW) techniques. The base metal of 316L ASS exhibited mainly austenitic grains, while the 410 MSS base metal displayed mainly martensitic microstructure. The fusion zone of the PTIG weldment showed austenitic grains and exhibited a martensite phase with precipitated carbide particles in the weld zone. The highest hardness was noted in the heat-affected zone (HAZ) of 410 SS grade (~254HV) as compared to 316L SS grade at HAZ (~168 HV) using GTAW. The PTIG weldment revealed higher toughness (~76 J) compared to GTAW (~62 J). Potentiodynamic polarization studies showed noble pitting potential (–0.251mV) for PTIG-welded joints as compared to GTAW-welded joints (–0.421mV). In comparison to GTAW-welded joints (17.264 × 10^–5 µA cm^–2), PTIG-welded joints had a significantly lower corrosion current density (0.46 × 10^–5 µA cm^–2), indicating higher corrosion resistance. The improved mechanical and better corrosion properties in PTIG-welded joints attributed to the controlled heat input due to the pulsing effect, which has resulted in less distorted microstructure and narrower heat-affected zone, and low chromium carbide precipitation around the welded joints, which helps in retaining the uniformity in the alloying element across the matrix.</p>
