Re: [MW:28594] Fwd: Weldolet thk

WPS : 2.27-11.54mm gtaw. CS.

We have 10mm pipe16" CS and 1" weldolet(16mm groove thk #Tm)

Shall WPS cover both the thk  to weld?

REPLY: WPS should cover the welded portions thickness and weld deposition.

Weldolet design thk(Tb) means 10mm shall consider for selection of WPS?

REPLY: (c) The nomenclature and symbols used herein, in Fig. 328.5.4D, and in Fig. 328.5.4F are Tb = nominal thickness of branch, Th = nominal thickness of header Tm = nominal thickness of the branch 
weld for integrally reinforced branch connection fittings, either
(1) as specified by the manufacturer of the branch connection fitting
(2) the full depth of the resultant weld groove, after fit-up, if no manufacturer's weld thickness is specified
(3) as documented and specified in the engineering design in accordance with para. 300(c)(3), or
(4) calculated and documented in accordance with the requirements of para. 304.7.2 Tr p nominal thickness of reinforcing pad or saddle tc p lesser of 0.7Tb or 6 mm (1⁄4 in.) tmin p lesser of Tb or Tr

Shall we weld up to manufacture line with same WPS

REPLY:Owners approved WPS for the project is mandated.

My opinion is we need to consider Tb 10mm thk  for weldolet and we can weld pipe to weldolet with available WPS.

REPLY: Just Contemplate,  your deposition will be within the approved WPS then you can use , as your PQR will be 5.57 and your 11.54 will be the max for deposition?

M.Muneeb.

Dear all,
B31.3/AsmeIX
WPS : 2.27-11.54mm gtaw. CS.

We have 10mm pipe16" CS and 1" weldolet(16mm groove thk #Tm)

Shall WPS cover both the thk  to weld?

Yes/NO

Weldolet design thk(Tb) means 10mm shall consider for selection of WPS?

Yes/No

Shall we weld up to manufacture line with same WPS
Yes/No

My opinion is we need to consider Tb 10mm thk  for weldolet and we can weld pipe to weldolet with available WPS.

Dear Exerts
 
what is Steel Grades S460NL & S500ML Are this is CS or it is alloy steels
like HARDOX , WELDOX and now they call it Domex?
 
what is it is specification ? standards? recommended usage and applications?

Hi,
 
my interpretation of the clause 3.6.1 is as follows;
A combination of, QUALIFIED and PREQUALIFIED WPS'S = I interpret this as
either qualified WPS+qualified WPS, Qualified+Prequalified or
Prequalified+Prequalified.
..may be used without any requalification for the combination.
 
So it nowhere states that existing qualified combinations can be split into
2 separate WPS's.
 
Above is my interpretation,
