| Butt cold pressure welding is a solid state manufacturing process with several important applications, but with a gap in its fundamentals. This paper presents a new approach of the research in the field, bringing both theoretical and practical original contributions to the knowledge and creating the bases for the development of new processes addressing modern materials. First, an overview of finite element method (FEM) used in butt cold welding is presented. Correlation between stresses and material deformation is further addressed. Original indicators related to cold welding process initiation are introduced: critical deformation, welding critical stress and welding critical radius. The paper brings an original interpretation of cold welding process based on FEM model and on microstructural considerations. Results of mechanical tests and of macro- and microscopic analysis are provided to validate the model. | |
