ASME Section IX Quiz

1 / 18

Which clause in ASME Section IX specifies that a Welding Procedure Specification (WPS) qualified for plate welding can also be used for pipe welding?

Clause QW-201

Clause QW-202

Clause QW-211

There is no such clause in ASME section IX

2 / 18

A Welding Procedure Specification (WPS) was qualified by conducting a Procedure Qualification Test (PQT) in the 1G position. Can that WPS be qualified for all positions?

No, the WPS can only be qualified for the 1G position

Yes, the WPS can be qualified for all positions including overhead position

The WPS can be qualified for all positions except 6G, as the 1G PQT is insufficient for 6G qualification.

The WPS can be qualified for all positions in fillet joint. However, only flat position in groove joints.

All Positions

Flat & Vertical

Flat, Vertical & Horizontal

Vertical Only

5 / 18

If a welder was qualified in the SMAW process on January 1, 2023, and last performed welding with SMAW on March 30, 2023, will he still be qualified on October 15, 2024?

Yes

Yes, but with close monitoring

Yes, but only for non-critical jobs first

6 / 18

What is the key difference between test positions 2F and 2FR for fillet welds in pipes?

In 2F, the pipe axis remains vertical, while in 2FR, the pipe axis remains horizontal and the pipe is rotated during welding.

In 2F, the pipe axis remains horizontal, while in 2FR, the pipe axis remains vertical and the pipe is rotated during welding

The pipe axis remains horizontal in both positions (2F & 2FR). However, the pipe is rotated in 2FR.

None of the above

1F, 2F, 2FR, 4F & 5F

1F, 2F, 2FR, 4F & 6F

8 / 18

A welder has passed the performance qualification test (WQT) in 3G and 4G positions on a groove welded joint test coupon prepared from a 16 mm thick mild steel (MS) plate. In which of the following positions is he qualified to perform groove joint on plate?

All Positions

Flat & Vertical

Flat, Vertical & Overhead

Vertical Only

9 / 18

If a WPS was qualified under the 1965 edition of ASME Section IX, can it still be used today?

Yes, it remains valid

No, it must be requalified to the current code

It can only be used for 1965-era pressure vessels

It is limited to repair welding, not new construction

10 / 18

The acceptance criteria for radiography tests of welder qualification test can be found in which of the following ASME codes?

ASME Section IX

ASME Section VIII Div. 1

ASME Section VI

The referencing code

11 / 18

What is the acceptance criteria for porosity (rounded indication) in a welder qualification test according to ASME Section IX?

1/8 inch (3 mm) maximum

20% of the total weld thickness (excluding any reinforcement) or 1/8 inch (3 mm), whichever is smaller

30% of the total thickness or 1/2 inch (12.5 mm), whichever is smaller

None of the above

12 / 18

Which of the following variables are generally considered as an essential variable in a WPS as per ASME Section IX?

Welder’s experience, type of welding machine, and cost of welding materials

Type of welding machine, cost of welding operations, and welder’s certification

Base material, filler material, P Number and preheat temperature

Welding position, welding electrode, P number and welder’s experience

13 / 18

When a tensile test specimen breaks in the base metal outside of the weld or fusion line, the tensile strength (UTS) recorded may be at the most how much below the specified tensile strength to be accepted as per ASME section IX?

10%

15%

Cannot be accepted if it breaks below the specified minimum tensile strength

14 / 18

A welder qualified with plate fillet welds in the 3F and 4F positions is qualified to weld groove welds in plate in which positions?
