In this work, two samples of service grade Esshete 1250 stainless steel, as-received and aged, were characterised to determine the microstructural differences between the parent material and weld in terms of the grain structures and the phases present using XRD, EBSD, SEM and EDS. There was
no difference found in the grain structure, but the phases present in the aged weld showed that sigma phase developed during aging.
