| Abstract: | For the performance of circumferential weld,the yield strength of weld metal is a critical factor in pipeline design.This article introduced match relation between steel pipe base material and weld metal,as well as yield strength distribution curve of base material.It discussed effect factors on yield strength of weld metal with high strength match.Finally,it put forward determination method of the minimum yield strength of weld metal during high strength match. |
