1. In sheet metal fabrication, what is the primary purpose of annealing
stainless steel?
A. To increase tensile strength
B. To harden the metal
C. To relieve internal stresses and improve ductility
D. To coat the surface
Annealing stainless steel softens the metal by relieving internal
stresses and enhancing ductility for easier forming.
2. Which tool is used to create a straight, precise bend in a sheet metal
part?
A. Laser cutter
B. Press brake
C. Spot welder
D. Plasma torch
A press brake uses dies and force to create accurate, straight bends
in sheet metal.
3. What is the common term for the process of cutting sheet metal using
a high-temperature ionized gas jet?
A. Waterjet cutting
B. Punching
C. Plasma cutting
D. Shearing
Plasma cutting uses an ionized gas jet to cut electrically conductive
materials with a hot plasma arc.
,4. When developing a flat pattern from a 3D sheet metal part, which
factor must always be considered?
A. Surface finish
B. Color of the metal
C. Bend allowance
D. Welding sequence
Bend allowance accounts for the length change in material due to
bending and is essential for accurate flat patterns.
5. What is the purpose of a relief cut in sheet metal design?
A. To add strength
B. To improve surface finish
C. To prevent tearing at bends or intersections
D. To apply surface coating
Relief cuts are used to prevent tearing by reducing stress
concentrations at corners or bend intersections.
6. Which gauge number represents thicker sheet metal?
A. 26
B. 10
C. 30
D. 32
Lower gauge numbers correspond to thicker metal; 10 gauge is
thicker than 26 gauge.
7. What is the recommended minimum flange width to ensure proper
strength in a bend?
A. Equal to stock thickness
B. Half the stock thickness
C. Three times the stock thickness
D. No minimum requirement
A flange width three times the material thickness provides sufficient
strength and reduces distortion.
8. What is the term for the buildup of material at the bend line due to
plastic deformation?
A. Wrinkling
B. Neutral axis shift
C. Springback
, D. Stretching
Neutral axis shift refers to the internal layer where material neither
compresses nor stretches; it influences bend allowance.
9. What process uses a tool that descends into a die to create holes or
shapes in sheet metal?
A. Laser cutting
B. Bending
C. Punching
D. Welding
Punching uses a punch and die set to shear holes or shapes out of
sheet metal.
10. What is the major safety concern when operating a plasma
cutter?
A. Low noise levels
B. Tripping hazards
C. Ultraviolet radiation and molten metal splatter
D. Chemical exposure
Plasma cutting creates UV radiation and molten metal splatter that
can cause injury without proper protection.
11. Which fastener is commonly used to join thin sheet metal
without welding?
A. Lag bolt
B. Weld nut
C. Pop rivet
D. Carriage bolt
Pop rivets are ideal for joining thin sheet metal where welding is
impractical.
12. What material property does tempering principally affect?
A. Density
B. Thermal conductivity
C. Toughness
D. Corrosion resistance
Tempering reduces brittleness and improves toughness after
hardening.
