Re: [MW:27306] What is the allowable inner penetration during pipe wedling

There are lot of Factors involved in Radiography to determine the Density Variation for the ID penetration depth. Moreover you use a Double wall viewing and it is very difficult to determine.

Other methods include

1. Boroscopy
2. Ball run Test. A steel ball with the required diameter shall be passed through the tubes and determine the depth of penetration.

Thanks & Regards

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.
