Abstract
This work, presents some heat treatments were used to improve the microstructure in different zones
of the API X70 welded pipeline steel. In this study a shielded metal arc welding(SMAW) process
has been realized.. Optical microscope and X-ray diffraction have been used as characterization
techniques to observe the WM microstructures. The results revealed that the isothermal heat
treatment caused restoration and recristallization reactions in al welded joint zones
