Dears
I will add one more point.
As per ASME IX ,welder can be qualified either through RT or bend test. In the bend test notes you will find that the reinforcement shall be removed before bend test (2010 edition)/Recommended to be removed before bend test (2013 edition).
So, I think it is not an issue

Subject: RE: [MW:22436] Grinding or filling is allowed on Final pass (oncapping) for WPQT ? Urgent plse..
Hello Nandesh,
Continuing the subject, you mention that -
Filing a completed weld for good visual appearance, is not a problem, I think.
Consider a situation where Fatigue Grinding is required on production welding. The joint is visual and NDT Tested and accepted with all examination.
However during grinding due to poor grinding skill, it is excavated more than requirement and results in lesser wall thickness.
Is this case shall be consider as "repair welding" There is no issue with the welding however it is now require to be "re-weld" or refill of cap.
Provide your view.
Best regards,

ASME Sec IX do not address this issue. ವಂದನೆಗಳೊಂದಿಗೆ / Best regards, P.S. : Please don't print this e-mail unless you really need to.
Mr. Sathis kumar, Codes do not specify about the grinding & filling, on not only final but even in filler passes. It is the discrepancy of the Inspection authority who witnesses the test. Some allow it while few do not. They feel it is lack of skill on the part of the welder concerned if he is allowed to grind such surface defect. But, it need not be a fact. Say if it is a surface pore due to sudden breeze or to other reasons where welder is not at fault, he takes the Inspector into confidence to remove such defects by grinding or other means. So it is a selective thinking. More attention is given in initial visual inspection for root defects like. LP, LF, UC, Ex. Penetration , Oxidation (in TIG process), Cavities, under flush etc., than on surface defects on cap runs. Sridhar. From: Sathish Kumar <sathishbemech@gmail.com> Dear Experts, Thanks in advance..
