Modeling of Thermel Transport for GMAW
Mathematical Problems in Engineering, 2012 Investigation of temperature distribution of submerged arc welded plates is essential while designing submerged arc welding joint because the key parameter for the change of weld bead geometry dimension, thermal stress, residual stress, tensile stress, hardness, and so forth is heat input, and heat input is the function of temperature distribution of ...

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
