The influence of the dimensions of the punch of a step-forming press on the stress-strain state in a pipe billet of longitudinal welded pipes of large diameter has been studied by the methods of finite element simulate. Pipes are made of steel X70. The kinetics of changes in the magnitude of deformations and stresses during one step of forming has been determined.
