Abstract:In this research, post-weld heat treatment (PWHT) of dissimilar API 5CT C90 and ASTM A182 F22 welded pipe was carried out at temperatures of 500, 600, 700 and 800°C. The effects of PWHT on the microstructure and mechanical properties of the weldment were investigated. The mechanical tests and microstructure examinations were focused on the fusion line area of API 5CT C90 as this area is the most crucial part of the weldment. The main objective of this research is to assess the microstructure and mechanical pro… Show more
