A welding technique where the heat and placement of weld passes in deposited weld layers is controlled
so that sufficient heat is provided to temper each previously deposited weld layer is known as:

API 510 Practice Test with Questions
and complete solutions
A welding technique where the heat and placement of weld passes in deposited weld layers is controlled
so that sufficient heat is provided to temper each previously deposited weld layer is known as:
API 577 3.1.65 - ✔✔Temper Bead Welding.
What materials are highly resistant but not immune to Cl SCC?
API 571 4.5.1.2 - ✔✔Nickel base alloys.
In brittle fracturing where can the fine shear lips be found?
API 571 4.2.7.5 - ✔✔Along the free edge of the fracture, or localized
necking around the crack.
The next planned examination of a pressure vessel shall include all CMLs that have the:
API 510 5.6.2.1 - ✔✔Highest corrosion rates and least remaining life.
, If a welder has qualified in the shielded metal arc welding, submerged arc welding, and gas tungsten
arc welding process but has welded in only one of them, qualification for the other two processes
remains valid:
ASME SEC 9 QW-322.1 - ✔✔6 months
One purpose of reviewing previous inspection reports is to ensure that:
API 510 7.1.2
* - ✔✔Estimated corrosion rates for new equipment are accurate.
A vessel has a single corrosion rate of 10 mils per year. The minimum vessel required thickness for both
the shell and the heads is 0.75 inch. The actual thickness of the heads is 0.95 inch and the shell is 0.90
inch. What is the vessel's remaining life?
API 510 7.2.1 - ✔✔15 yrs
A pressure vessel has been in non-continuous service for 15 years. During this time, it has been filled
three times for 2 years at a time, then internally inspected. The last internal inspection determined that
the vessel had 9 years remaining life. The next inspection is due:
API 510 6.5.1.1 - ✔✔Before 4.5 years of actual service.
Bulges and buckling in the metallic linings of pressure vessels normally indicate:
API 572 9.4.7 - ✔✔That cracks or leaks exist in the bulged section
of the lining or that pin holes exist in the adjacent welds.
Any change to the design temperature, minimum allowable temperature (MAT), or maximum
allowable working pressure (MAWP), shall be considered:
API 510 3.1.42 - ✔✔An alteration
After an alteration to a pressure vessel, a nondestructive examination (NDE) procedure may
be substituted for a pressure test only when:
API 510 5.8.8.1 - ✔✔The engineer and inspector have approved.
