Renewal of WPQ as per ASME Sec IX

[Vinod Palande]

Dear All,

As per ASME Sec IX QW-322.2 Renewal of welder qualification expired under QW-322.1 (i.e. welder has not welded with a process during a period of 6 months or more.) may be made for any process by welding a single test coupon of either plate or pipe, of any material, thickness or diameter, in any position, and by testing of that coupon as required by QW-301 and QW-302. A successful test renews the welder or welding operator’s previous qualifications for that process for those materials, thicknesses, diameters, positions, and other variables for which he was previously qualified.

If I have welder qualified in 6G position 1 year back and his qualification expired as per QW-322.1, then can I renew his qualification (i.e 6G position) by welding a coupon in 1G position of plate. Within how much time period after expiration of qualification I can renew the WPQ as per above clause.

Thanks In Advance.

Regards,

Vinod V. Palande.

Both the expiration(QW 322.1) & renewal(QW322.2) are inter related.
After expiration within 6 month if welder has  welded in any product form his renewal is possible as per his wpq(qualification).But after 6 month he has to give the test inwhich we want to qualify.
So my answer is no .You can not qualify welder after 1 year.
You have to qualify within 6 months

This is incorrect.  There is no time period after which a previously qualified welder can renew his expired qualification by a single test.

 

See Interpretation IX-83-117

 

There are numerous other Interpretations in this same general context:

IX-86-19

IX-83-128

IX-83-124

Hi

 

Simple explanation is as follows:

Continuity (Prolongation)

•When do Welder Qualifications Expire?

- QW-322.1 Expiration of Qualification.: The performance qualification of a welder or

 

welding operator shall be affected when one of the following conditions occurs:

(a) When he has not welded with a process during

 

a period of 6 months or more, his qualifications for

that process shall expire.

 

Continuity

 

•QW-322.2 Renewal of Qualification

(a) Renewal of qualification expired

 

under QW322.1(a) above may be made

for any process by welding a single test

coupon of either plate or pipe, of any

material, thickness or diameter, in any

position, and by testing of that coupon as

required by QW-301 and QW -302.

 

That successful test renews the welder or

welding operator's previous qualifications

for that process for those materials,

thicknesses, diameters, positions, and

other variables for which he was

 

 

previously qualified.

 

There is no time period after which a previously qualified welder can renew his expired qualification by a single test mentioned in ASME Sec IX.

 

Hope this explanation answers your query.

 

Regards

Hi Gents,

 

I would like to request your valuable opinion/time regarding 6mm Multipass fillet under water confirming to AWS D3.6-2010 acceptance to Class B (fit for purpose). Materials to be used is AS1111 Grade 4.6 Bolt over AS3678 Grade 250 26mm plate. This is required for repair/replace by welding the anode brackets in place, so no special requirements need to be considered.

 

Could you please advise, whether there is any major risk in doing so.

 

I understand the weldability of the 4.6 grade bolt is not that excellent and will have issues related to HICC. We are using the consumable Hydroweld FS as per attached. As this weld is not that for a critical application, please provide me your expert advice.

 

Please view below the pWPS extract I prepared FYI.

 

 

 

Procedure:

Grind off the stud back to the doubler plate, including any paint unit clean shiny steel surface is achieved.

Weld a M20 Grade 4.6 Hex Bolt to the doubler plate with CFW  all around.

Reinstall the anode bracket to this M20 Stud.

 

 

 

 

 

 

 

 

Regards,

 

Biju Kurian Pottayil
