Micrography of the longitudinal section of the line at the fusion line of the fitting, close to OD. It is possible to see that the base metal is austenitic and the weld metal is austeno-ferritic. In the center of the thickness the average hardness of the fitting is 250HV1 and the average hardness of the weld metal is 180HV1.
