This is only Good engineering Practice. You can perform MPI if there is any reason to doubt
for crack development. Otherwise it should not be cut.
Anyway final NDT is going to be performed.
There no such code requirement and I strongly recommend not to cut the same.

>Dear experts,

construction team kept the joints after root pass and hot pass welding, but our QC instructed

We are maintaining preheat at 150-Deg and inter pass temp 300-Deg
