        Abstract: The paper simulates the welding temperature fields of the ultra fine grain steel by the computer simulation, and obtains the thermal cycle curve. Meanwhile, the paper has predicted the grain size of HAZ in the base of the thermal cycle curve. The outcome of the prediction accords with the outcome of the experiment .
