Dear All,

In the cap pass of the SAW Welding, we have observed some minor cracks while performing MPI as you can find in the attached pics.

With pipes welded with the same parameters and almost the same condition, we are finding this kind of defect in some pipes, if anyone has come across such kind of defects, kindly share your experience and possible root cause.

Thanks in advance for your valuable inputs.
