RE: [MW:17846] Radiographic Film Interpretation Excess Penetration..

Parallax is a method to 'estimate' the depth of the discontinuity in the weld; not for the measurement of volumetric flaws. ವಂದನೆಗಳೊಂದಿಗೆ / Best regards, Nandesh Kumar Arasappa P.S. : Please don't print this e-mail unless you really need to. --- On Thu, 30/5/13, Jean Staton <Jean.Staton@metco-ndt.com> wrote: From: Jean Staton <Jean.Staton@metco-ndt.com> Subject: RE: [MW:17841] Radiographic Film Interpretation Excess Penetration..

But some techniques may be employ to do this measurement by RT. Also some joints may be shown their excess penetration on RT film If you didn't use such techniques and your joint is simple butt joint, so your answer is NO.    Regards   On Mon, May 27, 2013 at 12:54 PM, Dominic v.k.dominic <v.k.dominic@gmail.com> wrote: Dear friend , that code is API 1104.. my question is excess penetration how is measuring the rt film like ruler scale..your knowledge it is possible   Thanks Dominic V.K.     On Mon, May 27, 2013 at 10:28 AM, Babur Khan <mbabur.bwp@gmail.com> wrote: Dear friend, 1st you mention construction code which applicable if ASME B31.3-2008 then see Table 341.3.2 Acceptance Criteria for Welds and Examination Methods for Evaluating Weld Imperfections as per this L Height of reinforcement or internal protrusion [Note (8)] in For T w, mm (in.) Height, mm (in.) any plane through the weld shall be within limits of the applicable height value in the tabulation at right, ≤ 6 (1⁄4) ≤ 1.5 (1⁄16) except as provided in Note (9).

This is Acceptable or Not Acceptable. if Acceptable where is mentioned the code?
