Field Test Coupon Procedure:

 Simply take test coupons onto scaffold near the actual field weld. The test coupons must be of the same material and type etc and backed up with documentation. Set up test coupon in same position as actual field weld.This was the way we done production

test coupons in the past for ASME-Section VIII, DIV I when required. 

I hope this helps

Re: [MW:30668] Chemical analysis mentioning in WPS and PQR for hard facing overlay weld

Chemical analysis is not mandatory in PQR unless it is mentioned in WPS before PQR Qualification. Whatever the elements mentioned in WPS, it should be done in PQR. Ref QW 216.

Re: [MW:30668] RT film size required

There is no requirement for width. 

There is no requirement for the length of a single film.

There is a requirement for the minimum length to be radiographic in case of spot RT (read UW-52).

Each one welder's job has to be RTed.

One spot for each 15 meters of weld has to be RTed.

The min length of the spot is 150 mm

Re: [MW:30668] Chemical requirement of hardfacing weld(ER CoCr-A) on 1.6mm

When ASME BPVC Is applicable then:

1. The minimum thickness of hardfacing has to be specified in the WPS

The minimum thickness depends on which surface the chemical analysis or hardness test is conducted. You should read the Notes on Fig. QW-462(s)

2. There is no limit to the max thickness that can be used in production

3. The Chemical analysis has to be defined in the WPS. ASME does not impose any ranges/ In ASME it is not mandatory to specify a chemical analysis in the WPS, but if specified it has to be checked. However, the Classification of the filler metal is an essential variable, contrary to the ordinary welding (read QW-404.12)

Please through your view on below subject

1.What will be the qualification range, when a PQR is made by hardfacing weld(ER CoCr-A) on 1.6mm base to weld

2. What is the standard reference?

3. What is the Fe range allowed?

4. If range specified in WPS with limits with nominal chemical is that ok?

Re: [MW:30668] Chemical analysis mentioning in WPS and PQR for hard facing overlay weld

Your TPI is right, read the Code:

(d) When a chemical composition is specified in the
WPS, chemical analysis specimens shall be removed at locations
specified in Figure QW-462.5(b) or Figure
QW-462.5(e). The chemical analysis shall be performed
in accordance with Figure QW-462.5(a) and shall be within
the range specified in the WPS. This chemical analysis
is not required when a chemical composition is not specified
on the WPS.

If you specify the chemical analysis in the WPS then you have to confirm by testing that you achieved what you have specified in the WPS.

So read the Code carefully otherwise you shoot on your own legs

This is an essential variable and must be addressed in WPS of the following processes:

SMAW

SAW

GMAW & FCAW

ESW

EGW

a YES or NO has to be entered in the WPS if any of the above processed is involved.

Normally in SMAW,GTAW, GMAW,FCAW and mostly SAW you don't exceed 13mm of the weld metal thickness for each pass but mostly in Electrogas and Electroslag welding the Thickness exceeds 13 mm.

Re: [MW:30665] Difficulty in interpretation of ASME sec IX QW403.9

Thank you for the informative response. 

On Thursday, 18 April 2013 02:57:39 UTC-5, gerr...@yahoo.com wrote:

QW 403.9 states that if any weld pass in Single or Multi pass weld exceeds 13 mm (height of each individual pass) then the Base metal thickness beyond  1.1 times the Qualification thickness is an essentail variable that is for any change in Qualification Thickness beyond 1.1 T you need to qualify a new procedure.

 

Normally in SMAW,GTAW, GMAW,FCAW and mostly SAW you don't exceed 13mm of the weld metal thickness for each pass but mostly in Electrogas and Electroslag welding the Thickness exceeds 13 mm.

Also note, code allows SWPS - Prequalified WPS, means u can understand that does not require TPI involvement !

RE: [MW:30664] TPI approval on WPS

If you are working to ASME no third party witness is required.  Your Authorized Inspector (AI) will definitely have involvement but they are not required to witness WPS involvement.

 

If you are working to AWS no third party witness is required.

 

If you are working to ISO 15614, third party witness by a Notified Body (NOBO) is required.

 

If you are doing structural work for Canada.   CWB witness is required and a retained Canadian Chartered Engineer is typically also required for companies operating outside of Canada.

 

If you are interested – my experience – hope it helps.

For projects in middle east it is almost mandatory that a TPI is used although it is not a code requirement. In other countries u may follow what is prevailing in those countries.
