Hi experts i just want to know what will be the impact temperature reductions per Table UG84.2
(1) Base material thickness is 9.27mm.
(2) Deposited weld metal thickness - GTAW (4mm) & MAW(5.27mm)
(3) MDMT temp. is -31degree Celsius.
In my opinion it will be -50 degree C. is it correct for...

Hello experts pls answer this question,
A PQR was qualified as per ASME SEC IX with two process, GTAW and SMAW with weld metal deposit thickness (t) of 8 mm each in a 16mm base metal thickness (T) of plate. What will be the BASE METAL THICKNESS range T (not deposited weld metal thickness) if a...
Dear experts pls clarify my doubts,
As per asme sec 9 position is not an essential variable for WPS .
Let consider I have a pqr qualified in 1G position as per code I can use that WPS for Vertical position welding but by doing so how can I choose the parameters correctly.
The current range...

Dear experts,
"Vertical uphill progression qualifies for all position"!
The single statement is both valid for asme and aws code .
But what is the difference? Is there any difference between two?
Dear all,
Consider this situation an 8mm P1 plate welded against a 20mm P1 plate. Then the base metal qualified thickness range is 1.5 - 40mm and the deposited weld metal thickness qualified "t" is only 16mm. My question is what is the benefit of preparing a procedure so?
By using that...

Dear all,
While reviewing a PQR of thickness 22mm i found the PWHT time range is mentioned as 300 minutes and in WPS it is mentioned as 375 minutes.
The Pqr tested with impact test.
My question is that from whre did they get the soaking time of 300 minutes in PQR according to ASME SEC 8 UCS...
As per ASME sec 9
PQR 1 - GTAW T - 7.11mm , 1.5 to 14.22mm - A106 Gr.B
PQR 2 - SMAW T - 12.70mm, 5 to 25.4mm - A 106 Gr.B
No PWHT & No toughness.
My doubt is,1) is it possible to combine the above WPS to make GTAW &
SMAW combination.?
If possible wats thickness range.?
& Regardless of WPS...
