welding 2

[welding234]

Hi,
i have to establish a WPS as per ASME secIX for the following material,
API 5L x65 To SA694 F65
And
SA333 Gr 6 to SA694 F65
i have establish the single Procedure by Welding root GTAW ER 80 S2 and Other passes SMAW E-8018 G for the above two set material .
is ok as epr ASME SEC IX

welding234;
There is no SA 694. There is ASTM A 694. Is this procedure qualified with impact testing?

 

[welding234]

yes

 

[stanweld]

What design Code applies? If per B31.3, A-694 is unlisted. Each base mmaterial combination must be independently qualified.

 

[stanweld]

I stand corrected re ASME IX, wherein:
SA-336 Gr 6 is P-1 Group 1
A694 F65 is S-1 Group 2
API 5LX-65 is S-1 Group 2

Impact test qualificatiomn on P-1 Group 1 to to P-1 Group 2 or S-1 Group 2 qualifies P-1 Group 1 to S-1 Group 2 and S-1 Group 2 to S-1 Group 2. Both HAZ's must be tested and meet the Design Code requirements.

 

[welding234]

that means i need you estabhesh 2 procedure

 

[stanweld]

No.

 

[welding234]

as per your reply on 16/03
it supposed to be ,,,,orelse can give detail how it will be combined as one procedure as per SEC IX

stanweld,
I am a little confused.
QW 403.5 is a supplementary essential variable therefore it is applicable in this instance.
QW 403.5 Welding Procedure Specifications shall be qualified using one of the following :
(b)for ferrous materials, a base material listed in the same P-Number Group-Number in Table QW/QB 422 as the base metal to be used in production welding.

Based on that statement I would have thought that the welding of S1-Gr2 to S1-Gr2 and P1-Gr 1 to S1-Gr2 would have required two separate procedures. ?
Also, will impacts be at the same temperature for all three materials or do you just test to the lowest of the three ?
Regards,
BB

 

[welding234]

i too agree with ball bearing
what about stanweld.

Impact test qualification on one coupon composed of a P-1 Group 1 to a P-1 Group 2 or S-1 Group 2 materail and impact testing the weld metal, and the HAZ of both the P-1 Group 1 and the P-1 Group 2 or S-1 Group 2 material and meeting the impact toughness requirements of the original design Code qualifies to weld the joints defined in the original question.
