According to the characteristics of hammering force, a finite element mathematical model of hammering eliminating welding stress is established. By using this model, the welding process of white cast iron is analyzed. The mechanics and metallogenetic theory are used to study the effect of hammering treatment on eliminating welding stress Mechanisms. The results show that the hammering action under the proper specifications can effectively eliminate the welding residual stress and prevent the occurrence of cracks
