| Abstract: | The process and methods of calculating the conditions of pressure welding of hemispherical shells in local deformation are proposed. It is assumed that the material is viscoplastic. An energy method for calculating the parameters of the process is proposed. The results are presented and components and spherical containers made of a titanium alloy are described. |
