How to determine the position of the defect in the weld during flaw detection?

After detecting flaw waves in the weld flaw detection, the position of the defect in the actual weld should be determined according to the position of the flaw wave on the oscilloscope. The methods for locating defects are:

 

1. Sound path positioning method: When the instrument adjusts the scanning speed according to the sound path 1: n, the method used to determine the position of the defect is used.

 

2. Horizontal positioning method: when the instrument adjusts the scanning speed according to the level 1: n, the method used to determine the position of the defect.

 

3. Depth positioning method: When the instrument adjusts the scanning speed according to the depth 1: n, the method used to determine the position of the defect.
