Stainless steel 32750 (SS32750) is a duplex stainless steel renowned for its exceptional corrosion resistance and mechanical properties, making it ideal for demanding applications, particularly in harsh environments such as offshore and marine industries. This study examines the microstructure and mechanical properties of SS32750 weldments produced using two distinct welding techniques: Gas Tungsten Arc Welding (GTAW) and Laser Welding. The investigation focuses on the effect of various welding parameters, including heat input, welding speed, and shielding gas composition, on the resulting microstructure. Mechanical properties such as tensile strength, surface roughness, distortion, and weld integrity were evaluated using methods like tensile load testing, X-ray radiography, and wire-cut EDM. The study provides critical insights into the relationship between welding techniques, process parameters, and the resulting performance of SS32750 weldments.
