Dear Sir,

I have to weld SA 516 Gr.70 (37mm Thk) Tube sheet to SA 516 Gr.70 (10 mm Thk) Shell as per below given weld details.

I have Qualified WPS of P1 to P1 material for 20 mm max. Base metal Thikness.

Now as per QW-202.4 Thicker member Thickness shall be within the range permitted by QW-451. My thicker member thickness is 37 mm.

Kindly pls explain me to can I use WPS yes or No with explanation.

Dear hemant,

yes you can weld filler weld with bevel with 80C preheating.Attachment is only for ref:,

As per your joint design dissimilar joint case is not applicable.

you can straight weld with your existing WPS P1-P1 20mm max thickenss.

which process you are going to use.?

regards,

mohammed.

I assumed that your Tube sheet to shell joint is not a butt weld but a full penetration T joint.
So what matters is the groove depth

dear sir,

Agree.
for full penetration fillet weld, only thinner member qualification to be consider.

dissimilar joint QW 202.4, applicable when groove welding is in place.

pl correct me if am wrong.

Please explain a "full penetration fillet weld". In my experience, if
it is full penetration you have a square groove (T) weld with a fillet.
In which case you have to be qualified for both base metal thicknesses.
A fillet weld is qualified by any thickness groove weld.

Hi!

If both material is of P1

If you qualify PQR of P1 to P1 on 38mm thk plate you are satisfying all condition given in QW 202.4 a and b(2) and with this PQR you can weld between 5mm -200mm thinner component to any thicker component of P1(In your case) of any weld configuration

Hegde P.B.

Dear Sir,

My Qualified PQR is on 10 mm Plate thickness with P1 to P8 material. Now my Heat exchanger Tube sheet is P8 SA240 304 37 mm Thk and my shell is SA 516 gr.70 10 mm Thk.

Joint details is as shown below sketch. Kindly pls conform me can I do or not. Because I get 50-50% answer without any technical clarification. If possible pls help.

Thanks in advance.
