Abstract
The analysis of quality of large diameter welded pipes depending
on the parameters and modes of the slab forming on press equipment is presented. Mathematical modeling of the processes was performed using the finite element method. The results of the stress-strained state of metal during round billet forming billets in forging equipment are shown. Established computer program allows calculating of process parameters settings of press equipment to determine the value of controlled geometric parameters of round billets, required in the regulations. The theoretical solutions were experimentally tested on assortment of large diameter pipes, produced at TESA 1420. It is recommended to use this method to calculate the LDP forming parameters and pressing equipment settings that allows reducing the number of defects caused by the geometry of the fl anging press and JCO- press.
