Modeling and experimental comparison of residual stresses and microstructure in UNS S32507 welds using Gas Tungsten Arc and Laser Beam Welding processes

This study presents a comparative analysis of Gas Tungsten Arc Welding (GTAW) and Laser Beam Welding (LBW) on UNS S32507 duplex stainless steel, emphasizing thermal behavior, microstructure, residual stresses, and mechanical performance. A finite element thermal analysis using a Gaussian heat source...
