Preliminary Study of Metal Pipe Deformation Resulted from Cutting Machine in Electric Resistance Welding Pipe Production using Finite Element Method

Abstract

Edge of metal pipe resulted from cutting machine is deformed. The cross section is not circular in shape, outside diameter of pipe is out off specification. Deformed edge needed to be removed which increase waste in the process. In order to find cutting methods which could reduce the aforementioned problem, Finite Element Method (FEM) is applied. In this paper, it describes the validity of Finite Element results and relation between cutting speed and deformation. It can be seen that deformation of pipe obtained from FEM differs from physical cut pipe by 7-13 percents, and low cutting velocity leads to increase of pipe edge deformation.
