Sample WPS 1

PQR & WPS # SMAW-1-8, REV.
0 - PRACTICE QUESTIONS
←1) Do the mechanical tests support qualification of this PQR?
← Yes
← No, one tensile test failed.
← Face Bends and root Bends should have been performed instead of side bends.
← The 3/32” defect in the heat effected zone on the side bend tests is over the acceptable limit.
Note:
.758 x ,752 = .570 sq. in.
37850/57 x 100 = 66403.5
70000 x .95 = 66500
66403.5 , 66500 so the tensile failed & the report is incorrect
See QW-153.1 (d) (5% rule)
2) Is joint design fully addressed on the WPS?
← No, the sketch of the joint must also show weld layers & specify uphill or downhill.
← Yes
← No, root spacing is not addressed.
← No, spacing between backing strip & base metal must also be addressed.
Note:
If a sketch of the joint is not supplied and a note such as; “See drawings.” is entered in place of a
sketch it is not acceptable unless the sketch is supplied with the WPS. The WPS is used to provide
direction to the welder. It is not acceptable to allow the welder to choose the joint design or type he
desires.
←3) The full range qualified for the base metal thickness that may be welded with this WPS is:
← 1/16” to 1 1/2”
← 3/16” to 1 1/8”
← As shown on the WPS
← None of the above
Note: See Table QW-451.1
←4) The actual maximum throat dimension allowed for the weld metal thickness “t” for fillet welds:
← has been restricted by the WPS to 1” maximum throat.

← should be 0” to 8”
← is 1/16” to 3/4”
← is 3/16” to 1 1/2”
← 5) If a joint was made using this WPS and the welder put in a single pass with a deposited weld
metal thickness, “t”, of 9/16” :
← It would not make any difference.

← The welder would need to use a different electrode.
← The WPS would need to be requalified with a new PQR.
← Charpy production toughness tests would need to run.
Note: 1/2” “t” rule
← 6) The minimum preheat temperature that this WPS could specify without requalification is:
← 200O F
← 300O F
← 50O F
← 100O F
←7) To increase the full range qualified for “T” on the WPS to 3/16” to 2”:
← The original coupon used for the PQR would have to have been 1” thick.
← The WPS only needs editorial revision to allow the welding the thicker material.
← The preheat temperature needs to be increased to 300 O F.
← The method of back gouging must be restricted to grinding only.
← 8) The full range of A Number qualification which may be shown on the WPS is:
← A-1 through A-11, P-34 and P-4X

← As shown on the WPS
← A-1, Groups 1, 2 & 3 only
← Not covered by ASME Section IX.
WPS # GTAW - 1 REV. 0 and PQR # GTAW-2
1) The proper base metal thickness range shown on the WPS is:
← Correct as shown
← 1/16” - 1”
← 3/16” - 1/2”
← 3/16” - 1/4”
2) The shielding gas shown on the WPS is:
← Should be 75% AR 25% CO2
← Should be shown as 20-30 CFH
← Both B & C above
← 3) The proper preheat temperature range that should be shown on the WPS is:
← 100°F minimum
← 250° maximum
← 150° minimum
← 4) The PQR supporting this WPS:
← is properly identified and traceable to the WPS

← is not properly identified and is not traceable to the WPS
← is not traceable to the WPS
← must be PWHT’d per ASME requirements
5) A drawing or sketch of the weld joint:
← must be shown on the PQR

← must be shown on the WPS and PQR
← must be shown on the WPS but not the PQR
← none of the above
6) The tension tests shown on the PQR:
← are acceptable as shown

← are unacceptable because of mathematical error
← are unacceptable due to the size of the specimen shown
← are unacceptable due to the strength of the specimens; shown
7) The tension tests shown on the PQR:
a. are full size pipe specimens

b. are full size reduced section specimens
c. are reduced section turned specimens
d. are not required for this PQR
8) The bend tests shown on the PQR:
a. are acceptable as shown

b. are insufficient in number
c. are incorrect as to the type of bend test performed (i.e., side, face, root)
d. Both B and C above
9) The bend tests shown on the PQR:

b. do not meet the acceptance criteria of ASME IX
c. should be listed with the length of each specimen
d. need to be PWHT’d after bending
10) PQR #GTAW-2 is:
a. unacceptable because it was run in the 1G position and the WPS states all
positions are acceptable.
b. unacceptable because it is not certified.
c. unacceptable because it was run with backing gas and the WPS does not require
backing gas.
d. none of the above
11) The filler metal shown on the WPS:
a. has been properly qualified by the PQR

b. has not been properly qualified by the PQR

12) The amperage and voltage ranges shown on the WPS:

b. are unacceptable as qualified on the PQR
c. must be higher to properly run this size of electrode
d. none of the above
13) The best explanation for the problems observed on the PQR is:
a. Mr. Blow was insane at the time of preparation

b. Mrs. Blow was distracting Mr. Blow at the time of preparation (New swimsuit)
c. The test laboratory personnel just checked out of Betty Ford Clinic
d. The front and back pages of the PQR have been copied from separate documents
1) A
2) B
3) D
4) A
5) D
6) C
7) C
8) D
9) B
10) C
