A NCR is an opportunity for a corrective action on your process.
In that case to elaborate methods to minimize distortion.
Moque up: simulate the defect (distortion) on a specimen and then repair it.
After then perform tests over an above the usual PQR tests like hardness and micrography
to check if any metallurgical changes will occur on the base metal and on the non removed weld metal.
