    • Abstract
  • The concept of laser-induced welding was developed and the physical and heat source model for laser-induced welding were established in this paper. The quasi-steady state equations for moving spot heat source during laser-induced welding were built. The finite element analyses were conducted through MARC software for the temperature field during laser-induced welding of 304 stainless steel. The loading of the moving spot heat source in laser-induced welding was realized based on the equations by using secondarily developed subroutine. Meanwhile, the simulated values were compared to the experimental results by measuring the thermal cycling curve of temperature filed in laser-induced welding with high temperature thermocouples. The results show that the simulated values agreed well with the measured ones.
