The non-destructive testing of launch tube weld with
radiography was investigated and evaluated with AWS D1.1
standard. The paper started with preparation of launch tube and
radiographic inspection. X-Ray inspection then was done and gotten
the result. The judgment of inspection results were concluded by
certified person and finally, the evaluation with AWS D1.1 standard
was conducted as well.
The result shown that weld position P1 was not conformed to
AWS D1.1 which allowed size of incomplete penetration did not
exceed 4 mm. The other welds were corresponded to as mentioned
standard. Additionally, the corrective actions for incomplete
penetration either provided for future actions.
