I have a WPS supported by 2 PQRs that is going through 3rd party review (impacts required). There is a difference of opinion on the heat input allowed for the WPS. The governing codes are API6A and ASME IX. The production material is 1" thick. I've only posted a minimum amount of information...
I was wondering if someone could help with interpretaion to the last paragraph regarding fillet welds. Does this requirement apply to all fillet welds or just to P11 materials? The last sentence of that paragraph seems to indicate that the paragraph is only applicable to P11 materials.
I was...
I am trying to do a % austenite/ferrite count on a weld crossection of 2205. NACE MR0175 requres the count per ASTM E562. I have the standard, but have never used it before. It seems like it would be really difficult to do in the weld considering the microstructure. Has anyone followed the...
Having a problem with low nickel in the welds scanning with a XRF spectrometer. Checked pipe and it is around 10.5-11.0 and undiluted filler metal is 11.5-12 which matches the certs that were provided (we require actual chemistries). When we check the welded joints we are getting 8.75 to 10.5...
I have a compressor head (P1)about 36" dia X 8" thick that we need to weld in a 3" dia plug on outer diameter edge. The head gets final precision machining and we can not PWHT after this. Normally, we specify no more than 2" dia so we can make an as-welded fillet with no post weld heat treat...
Does this code define major and minor weld repairs? Where can I find it or can someone give me a head start? I know its a fairly generic quesiton, but it is mostly related to PWHT after a repair is made.
We want to do a low level stress relief for stainless steel. Our current WPS shows a range of 1650-2000F PWHT. The pqr used the 1650F. The way I read it, we can determine that range for this P number. Can I just revise the WPS with a new range? It appears that it is not that important for...
