- 9. Analysis of Occurrence:
Two instrument line samples each containing a weld which showed liquid penetrant: indications were subjected to metallurgical examination.
Photographs of the samplesL are attached -(Figures 1 and 2). -Both samples Jwere~ sectioned to explore the cause of the examinations. Visual exam-ination of longitudinal sections prepared from the samples disclosed crsvices- open to the external surface at the locations of the liquid penetrant indications. An over-all view of the longitudinal section --
- sm
.from PDT-1039 is provided_in the attached Figure 3. The crevices of both samples are in the same relative position, that is, at the center of the weld face.
Examination at a higher magnification of the surface crevices (as shown 2
.in Figure 4). indicate that they are interdendritic shrinkage imperfec- ,
tions. These are limited in_depty to 0.009 and 0.034 inch for sample PDT-1037 and PDT-1039 respectively. ,
