Finite element simulation of temperature field for submerged arc strip overlaying on thick plate

A thermal source for submerged arc overlaying is designed based on its principle and heat source model of Goldak, and a fortran subroutine is compiled to implement the translation of thermal source in the FEA software MSC.MARC. Finite element simulation of temperature field of submerged arc strip overlaying on thick plate was established. The simulation results are in good accordance with the actual thermal cycle curve, which proved the model is correct.
