What is Residual Stress in Multi-Electrode Welding about?

This chapter examines heat flow models and discusses the results of analyzing temperature distribution during multi-electrode submerged arc welding (ME SAW). Analytical, 2D, and 3D heat flow models were developed. The analytical model showed that a 1D approximation can be used when temperatures are below 9000C due to negligible through-thickness temperature gradients. The 2D model overpredicted temperatures compared to the 3D model but provided computational efficiencies. Element birth modeling in 2D captur
