General WPS
Clause 6 describes
what is the requirements for qualification testing Of a WPS and welding personnel
6.1 Scope
Which section begins welder performance quaification?
What is 6.16
Which table shows the production welding positions qualified by plate tests?
What is table 6.1
A contractor changes from SMAW to FCAW on an existing qualified WPS. What should the inspector verify?
Check the essential variable table to determine whether a change in processes requires the WPS to be requalified under clause 6
True or False:
A change from non low hydrogen to low hydrogen electrodes for SMAW requires WPS requaification
False-
(2) states a change from low hydrogen to non low hydrogen
How many parts is clause 6 divided into? Name each part
What is 4, General requirements, WPS qualification, performance Qualification, Testing Requirements
A welder passes a qualification test- Can another welder use that qualification
No, Each welder is required to qualify
Because qualification is limited to the positions permitted by the qualification tables.
A contractor asks why a PQR is required, What would be a response
What is To demonstrate through testing that the welding procedure can produce acceptable welds before it is used in production.
What does part C of clause 6 cover?
What is Performance qualification tests required by this code to determine a welders ability to produce sound welds
Scope Section 6.1
What processes may be used provided the WPS has been qualified using clause 6 of D1.1?
What is GTAW,GMAW-S, ESW, EGW
6.15.1
Tack welder qualification shall qualify for thicknesses greater than or equal to ?
What is 1/8"
Section 6.16.2.2
Using table 6.2 what would be the required number of bend specimens for a plate test 1/4" thick?
what is 6 total
Table 6.2
A welder qualified in one position has discovered welding in the field will be in a different position.
What should the inspector verify?
Verify if the new welding position is included within the qualified range in table 6.10
The table used for production welding positions when qualified by plate to create a WPS is?
What is table 6.1
When performing Visual inspection of a fillet weld during testing, undercut can not exceed?
What is 1/32"
6.10.1.2 (5)
The responsibility for testing and documenting a welder during testing is?
who is the employer of the welder
section 6.2.2.2
What is table 6.10 used for?
What is production welding positions for welder/welding operator
A welder is going to qualify by a plate test, what table would be used?
What is Table 6.10
What is the difference between a PQR and a WPS
A PQR documents the successful qualification test results while a WPS is the written procedure used in production welding
A welder who qualified using SMAW has not welded with that process in 8 months. Is he still qualified to weld with that process?
No, the welder must weld using SMAW within 6 months.
Section 6.2.3.1 (1)
If a welder qualifies using E7018, can he use a E7010 electrode?
Yes table 6.12 (2) E7018 is F4-E7010 is F3- Can use electrode with lower F numbers
For a transverse bend specimen with a plate, what is the required width?
What is 1-1/2"
Figure 6.8
A welder qualified using a groove weld now wants to make fillet welds-What table would you look at to determine if this is acceptable
A test has been qualified using a plate with a fillet weld in the 3F position. What Production welding positions are qualified?
What is fillet Plate, F,H and Vertical and pipe fillet F,H and vertical, and box tube welding fillet F,H, and vertical
