Abstract

The history of modeling weld phenomena in Japan can be traced back to 1940's. One early study worthy of note is the Tanaka solution to welding heat conduction, which was published in 1943, two years after Rosenthal's solution. Since then, a number of modeling activities have been carried out on various welding phenomena. In relation to the welding of C-Mn and low alloy steels, primary efforts have concentrated on improving the prediction of HAZ hardness and cold cracking susceptibility of weldments. In this respect, the present paper reviews the analytical and experimental modeling of heat conduction, hardenability, hydrogen diffusion, and residual stress carried out in Japan. The modeling of weld pool behavior, solidification and phase transformation has also been attempted to predict weld microstructure and weldability. In some recent studies, a thermodynamic calculation method has been introduced to improve the modeling of multicomponent steels.
