Numerical ModelLing and Simulation of a Moving Heat Source during Welding Process

Heat conduction of moving heat sources is a topic of interest in engineering problems such as welding, surface hardening, moving friction between mechanical parts, laser treatments etc. There is more impetus on studying a moving heat source both empirically and theoretically. The simulation of a welding process may involve the study on the temperature distribution and cooling rates. The simulation of moving heat source during welding process needs the knowledge of welding parameters, plate geometry and material properties. Study of welding process involves more sciences and variables than those involved in most other industrial processes. A numerical study of transient two dimensional heat conduction problem with a moving source is presented. The main ideas and details of the computational implementation are presented. Numerical results of the simulation of the heat transfer process are reported and validated.
