Re: [MW:16656] Required PQR Test Help

[Mohd Firdaus]

Is it your WPS need to be PWHT?. Supplementary essential variable. Then   what kind of project you prepared for this WPS?. Is it needed for back gouging?. 400 mm x 300 mm shall be ok for all testing that you mention. A516 Gr 70 shall be ok for charpy -46deg. Make sure your consumable use also high in charpy value. E7018-1 check this electrode.

Dear Experts,

Our company is going to make a new PQR and WPS but since I am new at ASME sec IX and B31.3, I would like to verify my tests before doing them.

So PQR specs are;

Thickness                              10mm (WPS qual. 10-15mm)

Mat                                        Plate - SA516 Gr60 & SA516 Gr70 (this will qualify bot P1G1 and P1G2 mats right?)

Preheat                                  38°C Min(client spec)

Interpass Temp                       250°C Max

PWHT                                   620°C (120min, 100°C/hr)

Pos                                       3G

Type                                      GTAW + SMAW

 

Tests:

2              Tensile Test

2              Face Bend Test

2              Root Bend Test

4              Side Bend Test (Do we need this?)

5?           Toughness Test (Charpy V-Noch at -46 C is enough?)

Hardness

Radiography

And the other thing is how big test coupon should I weld to get these tests.

Cc: pb.h...@yahoo.com Date: Friday, 1 February, 2013, 6:12 PM Thanks everyone for your answers, so welded 300mm width and 400mm long (parallel side of weld) plate is enough for all these test?YES  I am going to make 3 plate for normal, half repair and full repair PQR. Do I need to send both PWHTed and non PWHT PQR to lab----- Send both Coupon plate i.e. One for testing After PWHT and Scond coupon w/o PWHT Therefore you will be qualifying PQR 2 PQR one with PWHT and second w/o PWHT for or just 1 post weld heat treated PQR is enough for each of these tests? The other thing is our client referred ASME IX, QW 403.6. and told me with 10mm PQR I can only qualify 10to15mm thickness, If you weld PQR plate on 10mm this qualifies min  thk of plate welded to 2T ( in your case 10 to 20mm and not 15mm) r t I couldnt find max tickness standard at ASME is it 2 times of PQR if its above 6mm?  Or it depends on work? If they claim in scope of work that this project needs impact test then I use 10-20mm? and if not needed I ll use 5-20mm? Could you pls show me that standard? For Base metal thk qualification you have to refer ASME sec IX QW403.6 and QW403.8 to gether when Impact is asked ,If for non Impact WPS refer only qw403.8 Thanks again and Regards

Dear friend

Thickness                              10mm (WPS qual. 10-20mm)

Mat                                        Plate - SA516 Gr60 & SA516 Gr70 (this will qualify bot P1G1 and P1G2 mats right?)

you can not do this in your case as Impact test is required and G no is SEV.

Preheat                                  38°C Min(client spec)

Interpass Temp                       250°C Max

PWHT                                   620°C (120min, 100°C/hr)

PWHT should be determined as per cinstruction code.
If it is Div 1 follow UCS table for P no 1 material

Pos                                       3G (NON Essential Variable.)

Type                                      GTAW + SMAW

 

Tests:

2              Tensile Test

2              Face Bend Test

2              Root Bend Test

4              Side Bend Test (Do we need this?)

5?           Toughness Test (Charpy V-Noch at -46 C is enough?) at MDMT

Other DT should be as per QW-451.1

Hardness

Radiography

And the other thing is how big test coupon should I weld to get these tests.
