A study of evolution of temperature and velocity fields during gas tungsten arc spot welding of AISI 1005 steel using a transient numerical model was presented. Dimensional analysis was used to analyze the role of heat transfer by conduction and convection at various stages of the evolution of the weld pool. The calculated geometry of the weld fusion zone and heat affected zone and the weld thermal cycles were found to be in good agreement with the corresponding experimental results.
