Effect of Nitrogen‐Added Shielding Gas on Microstructure Evolution of Welded Joints by Gas Tungsten Arc Welding Process in Duplex Stainless Steel 2205

steel research international, Volume 95, Issue 5, May 2024.
A challenge in welding duplex stainless steels is to limit ferritization in the heat‐affected zone to ensure high corrosion resistance. The work describes the influence of nitrogen gas in the Ar–N2 shielding atmosphere during a gas tungsten arc welding process.

Optimization‐improved thermal–mechanical simulation of welding residual stresses in welded connections

Computer-Aided Civil and Infrastructure Engineering, Volume 39, Issue 9, Page 1275-1293, 1 May 2024.
Abstract This paper presents a novel computer‐aided computational framework to determine the optimum shape parameters in a welding heat source model using a coupled supervised Gaussian process regression (GPR) and genetic algorithm (GA) approach in estimating the welding residual stresses. The experimental X‐ray diffraction (XRD) approach validates the
