    PT requirement on root pass welding

    @david339933 I am so sorry you see that way and I still disagree. If this discussion continues, it only demonstrates there is no agreement about this topic yet, which is in line with my last 14 years work experience worldwide in this. Regarding the application of MR0175 to upstream and MR0103...

    PT requirement on root pass welding

    thread725-290810 Dear all, in reference with the above subject, please do note that the NDT guy can be right by requesting PT on a root weld. It is true ASME doesnt require such, but it is equally true that additional standards such as NACE MR0175 or NACE MR0103, referring to NACE SP0472...
