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.
The column have a flange of .5" and welding with E7018.
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.
Per the NBIC page below Texas stated current edition, having said that when did 2015 edition come out. If I annoy mistaking new edition are issued in January or June. So as Mike mentioned should it be implemented 6 months from date issued?
Construction:
ASME Code (Current Edition), Sections I...
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...
I'm sorry we are will be adding a new dock at a refinery in orange Texas. We will drive in pipe pilings to water floor and tie in with structure beams.
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 understand that Backing is an essential variable and the GTAW root pass is considered backing for the SMAW, but I don't understand why the statement would be made in QW-306.
QW-306 COMBINATION OF WELDING PROCESSES:
A welder or welding operator
qualified in combination on a single test coupon...
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...
The vessel will be rubber lined, having said that the hydro test has to be complete prior to the application of the lining. The tuber lining procedure has surface prep requirements of rounding nozzle openings to 6mm and smoothing out weld reinforcement.
