Welding Inspection and Metallurgy Exam (API-577) Practice Test

Questions # 1:

Base metals are assigned P-numbers by the ASME Code, Section IX to reduce the number of:

Options:

Required welding procedure specifications.

Required welding procedure qualifications.

Required procedure and performance qualifications.

Required mechanical tests.

Questions # 2:

Where is the weld HAZ assumed to be for purposes of hardness testing?

Options:

0.25 inch on either side of the fusion zone

0.25 inch away from the toe of the weld into the base metal

1 inch on either side of the centerline of the weld

Just adjacent to the toe of the weld

Questions # 3:

According to the PQR 8025, does the thickness range qualified concur with the thickness range as stated on the WPS 802?

Options:

Yes, but only for thicknesses greater than .280"

No, the material thickness on the PQR should be .375"

Yes, the PQR qualifies the ranges as stated on the WPS

No, the PQR thickness should have been .560"

Questions # 4:

To reduce exposure to moisture of low-hydrogen electrodes after they have been removed from the manufacturer’s packaging, they should be stored:

Options:

Under low humidity conditions.

In warm holding ovens.

In sealed plastic containers.

In tightly sealed ovens.

Questions # 5:

The deflection of an arc from its normal path that is a result of magnetic forces is referred to as:

Options:

Arc drift.

Arc strike.

Arc blow.

Arc deflection.

Questions # 6:

One of the main differences between welding nickel alloys and austenitic stainless steels is that with nickel alloys:

Options:

Interpass temperature control is not needed.

There is less susceptibility to cracking from contaminants.

There is less susceptibility to lack of fusion.

The weld pool tends to be sluggish.

Questions # 7:

The simplest weldability tests are those that evaluate:

Options:

Porosity and slag inclusions of the weld.

Cracking and corrosion resistance of the weld.

Strength and ductility of the weld.

Ductility and hardness of the weld.

Questions # 8:

What increases when a welder increases the amperage?

Options:

Voltage

Arc length

Heat

Questions # 9:

Hardness testing of production welds and the HAZ requires test areas to be:

Options:

Ground to a smooth contour.

Cleaned down to the bare metal.

Cleaned to remove surface scale and flux.

Clean, flat area or even flush with the base metal.

Questions # 10:

Which of the following is an important aspect of a qualified WPS?

Options:

Welder qualification

Maintaining project schedule

Welding program effectiveness

Fabrication quality control
