WebSep 1, 2024 · By identifying existing deficiencies in current codes and standards on the weld metal strength requirement, a formula predicting girth weld strain capacity was established in this work by considering high-low misalignment, fracture toughness, and girth weld strength matching factor for newly constructed pipelines. WebThe procedure accommodates misalignment at the girth weld, which can locally increase strain, using a combination of the elastic stress concentration factor and the Neuber method to transform stress into strain. The Neuber method enables the strain concentration factors arising from local geometric discontinuities such as misalignment and ...
