“…Heat conduction phenomena of material involving moving heat sources, which have attracted increasing attention by scientists and engineers in the past few decades, have been studied in a wide range of fields, such as welding, cutting, drilling, laser hardening/forming, plasma spraying, heat treating of metals, manufacturing of electronic components, and even firing a gun barrel, solid propellant burning, and dental treatment, see e.g., [1][2][3][4][5] and references therein. The most important physical quantity of interest for such practical applications is the temperature field of the medium, which is usually modeled by the heat conduction equation with time-dependent localized source terms for moving heat sources.…”

This paper focuses on efficiently numerical investigation of two-dimensional heat conduction problems of material subjected to multiple moving Gaussian point heat sources. All heat sources are imposed on the inside of material and assumed to move along some specified straight lines or curves with time-dependent velocities. A simple but efficient moving mesh method, which continuously adjusts the two-dimensional mesh dimension by dimension upon the one-dimensional moving mesh partial differential equation with an appropriate monitor function of the temperature field, has been developed. The physical model problem is then solved on this adaptive moving mesh. Numerical experiments are presented to exhibit the capability of the proposed moving mesh algorithm to efficiently and accurately simulate the moving heat source problems. The transient heat conduction phenomena due to various parameters of the moving heat sources, including the number of heat sources and the types of motion, are well simulated and investigated.

This paper reviews the interpretation of phenomena resulting from a thermal effect requires, as a necessary condition, knowledge of the temperature reached. The temperature is added one or more time conditions, whether it is the heating, the temperature stay or the cooling. So can say that the relationship between the heat entering the metal during welding obtain the temperature distribution, the thermal and residual stress. In this work we have measured and calculated the residual stress of the X70 steel welding procedure by the DRX-sinψ2 method before and after relaxation operation on the samples chosen after the estimation of this constraint by the finite element method. Solver, ABAQUS, the result indicates value of residual stress is about 146.67N/mm 2 after relaxation and about 96 N/mm 2 after relaxation at 0.5h and 50N/mm 2 AT 2h.
