| Abstract: | The echo height exceeding prescrihed level often appears in the double-submerged arc-welded steel pipe weld ultrasonic detection,which is to seriously affect defects judgements for inspection personnel.The characteristic wave echo of some defects such as inclusion,crack and chemical composition segregation was introduced by examples,and the judge methods for false defect wave were putforward also. |
