AWS D1.1 - CPJ to PPJ
(OP)
I would like to use a AWSD1.1 qualified full penetration joint , where the root is done by TIG and fill/cap with FCAW , to perform a partial penetration weld using a FCAW GS only. Is this is allowed under the AWS D1.1 noms. If so please also advise ether section in AWS which support this .





RE: AWS D1.1 - CPJ to PPJ
Why do you feel a weld procedure qualified and intended for full penetration joint can be used "as-is" for a partial penetration weld?
Different processes can be used as you indicate for root and cover passes. But the basic requirements for using a standard, pre-approved welding procedure is that you do in fact follow the entire procedure!
RE: AWS D1.1 - CPJ to PPJ
Unlike ASME IX a CJP doesn't automatically qualify a PJP or Fillet.
Additional tests are required as noted below.
4.10.3 Verification of CJP Groove WPS by Macroetch.
When a WPS has been qualified for a CJP groove
weld and is applied to the welding conditions of a PJP
groove weld, three macroetch cross-section tests specimens
shall be required to demonstrate that the specified
weld size shall be equalled or exceeded.
Cheers,
DD

As for "eliminating" a process from a dual-process qualified WPS, the answer is no. See AWS interp I-9/91-10-03.
