Sankaran,

I believe you need also to check on what WPS does state.

Dear Experts,

During pipe to pipe welding by single V butt joint by GTAW process (example : 1" XXS P91 pipe), there is a weld reinforcement over the groove and maintained 2 to3 mm of height, such a way ID penetration is also there. How much of height ID penetration is allowed? which is to be checked by RT exam. Kindly clarify and give me any supporting/ document  reference.
