Should the tube sections be rounded first and then inspected for defects, or vice versa?
It must be to round first and then conduct flaw detection; if the order is reversed, what if there are no issues with the flaw detection but problems arise during rounding?
After the longitudinal welds of the tube section are welded, it is first rounded before flaw detection is carried out
Of course, it’s necessary to round the shape first and then conduct flaw detection; it’s surprising that there are doubts even about this
Haha, Lao Yu, what problem have you discovered again? Send the picture out.
The tube sections are first rounded and then inspected for defects...
Is it possible that the part fails inspection before rounding, making the rounding process pointless?
All the manufacturers I know first calibrate and then conduct flaw detection.
It must be that rounding is carried out first and then flaw detection. We can assume that flaw detection is done first, and if the results are satisfactory, there may still be defects in the welded joint that are within the limits permitted by the inspection standards. Only after rounding do these originally permissible defects might expand under the applied stresses, turning into defects that are no longer within the scope of what flaw detection can detect; thus, flaw detection fails to serve its purpose of actually identifying defects.
If it fails the inspection later, it can be repaired. In the case of automatic welding, it might be necessary to undergo another inspection process
It should be to inspect the campus first, and then conduct the flaw detection in its final state
