When performing weave technique on pipe weld per the WPS is there a code specific on max of how wide the weave can be in a single pass using GTAW process? I can not find in any ASME or API code. I would think that as long as you keep your machine settings in the parameters of the WPS, it...
We are splicing column to top of existing column full pin welds what type of load would that beregarding RT acceptacne criteria per D1.1.

when welding structural beams to existing structure such as pipe rack will ASME sect 9 WPS and PQR be acceptable or is AWS WPS have to be used. In Texas.
Hello, I need some help understanding filler metal change on WPS from what I understand if you stay within the same F# on WPS you would not need a new WPS. Example, changing filler metal from ER70S-2 to ER70S-6 on a WPS the F# is the same but the A number is not. Per ASME would this be allowed...
We had contractor A start replacing some tubes on a Steam boiler, contractor A did not finish the repairs (had to leave plant unexpectedly) and a sister company of contractor A with their own R stamp is going to complete the tube replacement. My questions are how should that be handled as far as...
We are building a carbon steel pipe spool piece that requires elavated preheat in lieu of PWHT, with required preheat tempature of 350 degrees and Hardness testing with max reading of 200, I would like to know if the BNH readings have to be complete on all the welds including the shoe to pipe...
Got a question to clarify when PWHT is required. B3.3 requires pwht for material over .750", so can a PQR per ASME sect IX have been done on a plate 1.5" thk. Without pwht and can a WPS use this PQR for a max thk of 8" without PWHT.
Is there any asme code that specifies which way the nut has to be on a bolt, is there such thing as a backword/upside down nut? I know the material/grade should be showing when checking a bolt up connection. I'm just wondering if 1 nut out of 45 is backword (not showing 2H) is this good reason...
I need help to understand the statement made in ASME Sect IX it basically states that If a welder or welding operator qualifies in combination on a single test coupon the welder can weld in production any of his single processes or combination of his processes. So if he completed a 2" sch160 in...
We are building a new pressure vessel per ASME Sect VIII Div 1. We have completed the vessel and pressure tested the vessel with AI present and stamped. Now we noticed the Client drawings call for the internal welds ground flush. Do we have to re-hydro the vessel if we just grind the welds...
I am in Texas we have a contractor performing a NBIC repair on a coded vessel. The work was performed two weeks ago the AI signed the R1 today the name plate is being installed on the vessel after it was put in service. My question is is there any Code requirement that the AI witness the...
We have a new exchanger bundle built to Sect8 Div1 by an out side supplier, there are two nozzles with pup piece welded on each. We the contractor will weld a new flange to one pup piece and a spool piece consisting of a 90 and flange to the other pup piece. My thought is that this would require...
We are Going to be making some strength welds on a tube to tube sheet joint we have a calculated min weld size of .053" and max weld size of .168". We submitted a wps and PQR to client welding engineer and it was returned as rejected. The client stated that the PQR has a specified min weld size...
During an In process inspection of supplier the third party inspector found the supplier using ER70S-6 instead of the WPS specified ER70S-2 filler metal. The supplier agreed to remove the S-6 and reweld with the required S-2. My question is will this be justified NCR on supplier? I know the S2...
