The law how these factors influence the joint"s property was pointed out. A formula about the relationship between extrusion times and contamination remainder was founded. Main reason to bimetal"s inharmonic deformation was the difference of their mechanical property. Thereby, the empirical formula showing the relation between metal combination"s mechanical property and quality of joint was constructed. Integrated influence of extrusion times and metal"s mechanical property to quality of cold pressure welding joint was discussed.
