In the former case, the following problems are liable to occur:
1. the flaw detection report of the welding seam may not cover the complete condition, the flaw detection is not carried out on the individual welding seam, or the flaw detection is not carried out on the repaired welding seam;
2. the output of the flaw detection report is too lagged, so that the overall data management is influenced;
3. the flaw detection is not timely, and the entrance installation and use of the component are influenced.
