Regarding Deletion of welding Process.

[Madhu]

Dear ALLExperts,

I badly need your help for Deletion welding
Process for Using fillet welding Structural.

I have Qualified W.P.S (GTAW-root/hot+SMAW -fill/
cap)for Piping welding as per SEC-IX
& its qualified for fillet in all dia/size/
thickness & diameter as per SEC-IX.
Can I use only SMAW process for Fillet welding
In structural or Only GTAW process can be used.

Or I have to Use both GTAW+SMAW process.

Kindly Enlighten me regarding this matter or any
code clause I have to follow ( ASME-B31.3 & Shell DEP Standard.)




Thanks & Regards

Madhusudan Rout.

Wishing All of you & Your Families A Healthy & Prosperous New Year.

Dear Experts,

I need the coorect clause fro deletion of process which
will be use for structural fillet wed, Is it mention on any
International Standard, ASME or Shell DEP,
here Our client disagree with this piont , if Wps with GTAW+ SMAW.

Only SMAW can not use.

I need some refrence form you.

Thanks & regards

Hi

// Can I use only SMAW process for Fillet welding In structural or Only GTAW
process can be used.//

For structural welding, if you are using AWS D1.1, then you cannot use this
WPS.
If you are using ASME Sec IX, you can delete any process and weld with
either GTAW or SMAW for fillet welds (without open groove).

Please note that Joint design is a non essential variable for WPS (ref QW
253 and QW 256). However it is an Essential Variable for Welder
qualification (Deletion of Backing). Ref QW 356 and QW 353. So, here, for
SMAW process, either the weld metal or the base metal can be considered as
backing.

But, however , in addition to Code requirements, the Client specifications
shall be honored and followed. Some clients does not allow this process
deletion in their spec.

Good day Rout..
You can read also interpretation no. IX-04-08

Question: May this PQR support a WPS for welding with only one or two
of the processes shown on the PQR?

Reply: Yes, provided the following are met:
a) The remaining essential, nonessential and supplementary essential
variables, when applicable, are applied.
b) The base metal and deposited weld metal thickness limits of
QW-451 are applied.

Please read ASME Section IX QW-200.4(a) 3rd paragraph - to whit:
"When following a WPS that has more than one welding process, filler
metal, or set of variables, each process, filler metal, or set of
variables may be used individually or in different combinations
provided: (1) the essential, nonessential and required supplementary
essential variables associated with the process, filler metal or set of
variables are applied (2) the base metal and deposited weld metal
thickness limits of QW-451.1 for each process, filler metal, or set of
variables are applied."

So as far as ScIX is concerned, you may use either SMAW or GTAW or you
may used combined SMAW and GTAW.

Shell may have a different opinion, you would have to read their
specification.
