In this study, radiographic images obtained from fluoroscopic examinations and macrograpgic images of API 5L X65 pipe joints welded within the parameters determined by Taguchi method were examined in detail. In the obtained radiographs and macrographs, defects such as inadequate penetration and fusion deficiencies were observed in the joints 2 and 4, which were connected with the basic electrode from top to bottom direction. It has been found that all joints except joints 2 and 4 are generally performed perfectly. There are also no discontinuities that can be evaluated at the macro level in terms of defect size |
