In the obtained radiographs and macrographs, defects such as inadequatepenetration and fusion deficiencies were observed in the joints 2 and 4, whichwere connected with the basic electrode from top to bottom direction. It hasbeen found that all joints except joints 2 and 4 are generally performedperfectly. There are also no discontinuities that can be evaluated at the macrolevel in terms of defect size</p></trans-abstract>
