1. When preparing to lift a large boiler component, which of the
following must be checked first?
A. The color of the load
B. The weight and balance of the load
C. The location of the nearest fire extinguisher
D. The material composition of the load
Answer: B) The weight and balance of the load
Rationale: Before lifting any large boiler component, it’s essential
to ensure that the load is within the lifting capacity of the crane or
hoist, and the load is balanced to prevent accidents or damage
during the lift.
2. Which of the following tools is commonly used to clean slag
and impurities from a weld during the boilermaking process?
A. Hammer
B. Chipping hammer
C. Sledgehammer
D. Pneumatic drill
Answer: B) Chipping hammer
,Rationale: A chipping hammer is used to remove slag and
impurities from a weld, which is essential for ensuring the quality
of the weld and preventing defects.
3. In which of the following scenarios would a boilermaker be
most likely to encounter "cold working"?
A. Welding a hot, newly forged steel plate
B. Cutting and shaping steel at ambient temperature
C. Heating metal to make it more malleable
D. Installing insulation on a newly installed boiler
Answer: B) Cutting and shaping steel at ambient temperature
Rationale: Cold working refers to the process of shaping and
forming metal at room temperature, which is commonly
encountered during tasks like cutting, bending, or shaping steel
for boiler construction.
4. In boilermaking, which of the following would most likely cause
a "thermal shock" to a boiler?
A. Sudden cooling of a hot boiler
B. Slow, gradual heating of the boiler
C. Consistent temperature regulation
D. Gradual loss of pressure in the system
Answer: A) Sudden cooling of a hot boiler
, Rationale: Thermal shock occurs when a boiler is cooled too
quickly, causing stress and potential cracking due to the rapid
change in temperature.
5. Which of the following is a method of joining pipes used in
boilermaking?
A. Bolting
B. Riveting
C. Flanging
D. All of the above
Answer: D) All of the above
Rationale: In boilermaking, pipes can be joined using various
methods, including bolting, riveting, and flanging, depending on
the specific application and the design requirements of the boiler
system.
6. When cutting steel plates for boiler construction, which of the
following tools would be most commonly used?
A. Plasma cutter
B. Manual saw
C. Hydraulic jack
D. Drill press
Answer: A) Plasma cutter
following must be checked first?
A. The color of the load
