Q1 (WPS). The base metal thickness range is shown on the WPS:

(a) Is correct

(b) Is wrong – it should be 1/16 in–1 1/2 in

(d) Is wrong – it should be 3/8 in–1 in

Q2 (WPS). The deposited weld metal thickness:

(a) Is correct

(b) Is wrong – it should be ‘unlimited’

(d) Is wrong – it should be 2 in maximum (QW-451.1)

Q3 (WPS): check consumable type. The electrode change from E7018 on the PQR to E7016 on the WPS:

(a) Is acceptable (QW-432)

(b) Is unacceptable – it can only be an E7018 on the WPS

(d) Is unacceptable – the only alternate electrode is an E6010

Q4 (WPS): preheat check. The preheat should read:

(a) 60 °F minimum

(b) 100 °F minimum

(d) 300 °F minimum

Q5 (PQR): Check tensile test results. The tension tests results are:

(a) Acceptable

(b) Unacceptable – not enough specimens

(d) Unacceptable – specimen width is incorrect

6. Q6 (PQR). The bend test results are:

(a) Acceptable

(b) Unacceptable – defect size greater than permitted

(d) Unacceptable – incorrect figure number – should be QW-463.2

Q7 (PQR): validation of PQRs. To be ‘code legal’ the PQR must be:

(a) Certified (QW-201)

(b) Notarized

(d) Witnessed

Q8 (WPS/PQR): check if variables are shown on WPS/ PQR. Essential variable QW-403.9 has been:

(a) Correctly addressed on the WPS

(b) Incorrectly addressed on the WPS

(d) Both (b) and (c)

Q9 (PQR): variables are shown on WPS/PQR. The position of the groove weld is:

(a) Acceptable as shown

(b) Unacceptable – it is an essential variable not addressed

(d) Both (b) and (c)

10.

Q10 (PQR/WPS): variables. The PQR shows ‘string beads but WPS shows ‘both’ string and weave beads. This is:

(a) Unacceptable – does not meet code requirements

(b) Acceptable – meets code requirements (non-essential variable QW-200.1c)

(d) Acceptable – if weave beads are only used on the cap
