What type of error results from a poor layout and fit-up? (Multiple choice)
options:
A) A structural type error.
B) A dimensional error.
C) Property deficiencies errors.
D) A mechanical error.
- Correct Answer - B) A dimensional error.
According to CSA W47.1, how much undercut is allowed when visually
inspecting a welded test assembly? (Multiple choice)
A) 1 mm
,B) 1.6 mm
C) 2 mm
D) No amount of undercut is allowed. - Correct Answer - A) 1 mm
According to CSA W59, what is the maximum size of a single porosity
pore allowed when completing a visual inspection? (Multiple choice)
A) 2.5 mm.
B) 3 mm.
C) 3.2 mm.
D) No porosity is allowed. - Correct Answer - A) 2.5 mm.
Which non destructive process is best suited to discover incomplete
fusion? (Multiple choice)
A) A guided bend test.
B) A magnetic particle inspection.
C) A liquid penetrant inspection.
D) An ultrasonic inspection.
- Correct Answer - D) An ultrasonic inspection.
What preventative measure can be taken to prevent oxidation inclusion?
(Multiple choice)
A) A chemical treatment.
B) Passivation.
C) Cleaning.
D) Purging. - Correct Answer - D) Purging.
According to CSA W47.1, how much concavity is allowed when visually
inspecting the root surface of a welded test assembly? (Multiple choice)
A) 1 mm
, B) 1.6 mm
C) 2 mm
D) No amount of concavity is allowed.
- Correct Answer - C) 2 mm
What are the three categories of weld discontinuities?
Defective properties, physical discontinuities, mechanical properties.
Structural discontinuities, geometric discontinuities, defective properties.
Geometric discontinuities, defective properties, chemical properties.
Physical discontinuities, chemical properties, mechanical discontinuities.
- Correct Answer - Structural discontinuities, geometric discontinuities,
defective properties.
All discontinuities are defects.
True.
False. - Correct Answer - false
Defective properties relate to issues with
- Correct Answer - with the mechanical or chemical properties of the
parent material and/or the filler material.
An incorrect welding procedure can lead to a metallurgical condition
known as
- Correct Answer - Intergranular carbide precipitation. This leads to a
loss of corrosion resistance in the area adjacent to the weld.
When stainless steel is welded by using carbon steel electrodes, too
much dilution in the weldment is the most common reason for the loss of
corrosion resistance.
True.
