It may mention in wps the method for interpass cleaning, it can be followed for cleaning the completed joint...but for wqt normally none of the inspectors will not allow ( even contractors) becoz to insure the quality of welders...if a welder who is not able to deliver a sound weld, pass wqt, will be more headache for the welding inspector and the contracting company itself...so better not to allow..

--Dear Experts,
Please advice.
whether Grinding or filling is allowed on Final pass (on capping) for Welder performance qualification test (WPQT) for Plate or Pipe. Since qualification is done based on ASME Sec 9, so i need reference only as per ASME Sec 9.
Also already i referred ASME Sec 9 - QW194, which only mentions the Complete joint penetration for visual examination for WPQT. But it is not more specific in case of Grinding or filling and also some other (acceptable limits ? )parameters like Reinforcement, undercut, underfill etc..
I need only Asme Sec 9 reference, because as per the project contract only Asme Sec 9 is applicable for our project in case of WPQT.
please advice guys..Thanks in advance..Regards
