A Study on Mechanical Stress Relleving in a Butt-Welded Pipe

파이프 용접에서 기계적 잔류응력 이완법에 관한 연구

  • Published : 1996.02.01

Abstract

The heat transfer and thermal stress-distribution were numerically determined by using the finite element method for a butt-welded pipe. A mechanical stress relieving(MSR) treatment which has been frequently used in the fabrication of pressure vessels instead of the post weld heat treatment (PWHT) was also simulated to investigate its effect of reducing the residual stress in the welded zone by a mechanical loading.
