There are a lot of discussions in this thread, so please allow me to give my 2 cents worth. In Section IX, QW-410.5, it specifies the "change in the method of initial and interpass cleaning (brushing, grinding, etc.)" This is in the Section of the Code Book that is called "Welding Data". As a W.E. (also a CWI and CWE) I have written and assisted in writing many PQR's and WPS's. On all WPS's that I've ever written, there is a section called Technique (QW-410) where it sets the guideline for the cleaning of the welds. After the initial PQR is written and it is approved by mechanical testing, then a WPS is generated. The WPS, Welding Procedure Specification) is then generated by transcribing the acceptable data from the PQR to the WPS. As we all know, the WPS is the guideline that the welder(s) follow for acceptable welding due to testing. When the method of cleaning (QW-410.5) is described on the WPS, it is my opinion that it is the responsibility fo the WELDER to follow all parts of the WPS, including the cleaning of the welds as described in QW-410.5. Any welder worth is weight in welding rods will automatically clean all his welds unless he is trying to hide something. Not to clean his welds shows a lack of professionalism, integrity, but mostly a total lack of pride. Many years ago when I was working as a CWI, I did have to randomly clean a weld or two when radiography was ready to start, or PT was going to be done, etc., but I always carried a notebook with me and I noted the welds I had to clean and always let the welder know that it is HIS job to clean his own welds. To me, cleaning the welds is just as much a part of the welding process as burning the rods. Welders should make sure ALL of the guidelines of the WPS are followed before walking away from that weld. Then, that is when the CWI starts doing his job of inspecting. Failing to follow ALL aspects of the WPS is a violation of that procedure, including cleaning. swnorris, this thread was not directed at you, I just clicked on the "reply" button under your response. :)
