Hi all,While it seems reasonably simple to measure a weld for size after it has been sectioned, there are times when the geometry makes it difficult without a standard. For example, where specifically is the measurement taken from, and to, for depth of penetration for a PJP groove weld with a flair-v-groove edge prep? I happen to know the answer but am looking for a specification (or even a written guide) to use as a standard. I would assume that there is something in writing that describes a standardized way to measure sectioned welds of every configuration. Does anyone know where I can find anything like that?Thanks a lot!

Reply:Here is a bit from D1.1 pre-qualified joints. Not sure if im clear on exactly what you are asking but hopefully this helps.  Generally flare bevels are measured like any other groove weld, across the face as represented by the longer dashed line.Depth of penetration is tricky, because of the varying joint geometry that can be encountered under this one classification.  Generally as long as the weld face of tb is fully fused the standard is met.Your looking for just any standard? AWS D1.1 is probably the one you want to start looking at.  The second image is more along the lines of what you are looking for I believe. Attached ImagesHave we all gone mad?
Reply:The weld leg lengths and throat sizes should be determined on the WPS (welding procedure specification) those should be calculated by the welding engineer. As for the actual measuring of the weldment......I dont know of a written document that covers the actual layout of weldment inspection starting points, in real situations and outside of the lab. Good question......A young green pipe welder asked an old salt one day...How can I make the weld on the bottom of the pipe look like the top.......The old salt replied....Screw up the top......
