1. A metal fabrication technician is preparing to cut 3/8-inch mild
steel plate using a plasma cutter. Which factor has the greatest
influence on achieving a clean cut with minimal dross?
A. Paint color on the metal
B. Correct amperage, travel speed, and torch height
C. Shop lighting intensity
D. Air compressor color
Answer: B. Correct amperage, travel speed, and torch height
Rationale: Proper plasma cutting depends primarily on selecting the
correct amperage, maintaining the proper standoff distance (torch
height), and using an appropriate travel speed. Incorrect settings
produce excessive dross, beveling, incomplete penetration, or poor edge
quality.
2. During fabrication, a technician notices a blueprint dimension of
1250 ±0.25 mm. What does this specification mean?
A. Part must be exactly 1250 mm
B. Part may vary by ±2.5 mm
C. Part may measure between 1249.75 mm and 1250.25 mm
D. Part may measure between 1248 mm and 1252 mm
1
,Answer: C. Part may measure between 1249.75 mm and 1250.25
mm
Rationale: Tolerance defines acceptable dimensional variation. The
manufactured component remains acceptable as long as measurements
remain within the specified tolerance limits.
3. Which measuring instrument provides the highest precision when
measuring shaft diameter during fabrication?
A. Tape measure
B. Steel rule
C. Outside micrometer
D. Carpenter's square
Answer: C. Outside micrometer
Rationale: Outside micrometers commonly measure to 0.001 inch or
0.01 mm, making them ideal for precision fabrication work requiring
tight tolerances.
4. Why is layout dye commonly applied before scribing fabrication
lines?
A. Prevent rust permanently
B. Improve weld penetration
C. Increase visibility of layout markings
D. Lubricate cutting tools
Answer: C. Increase visibility of layout markings
Rationale: Layout dye creates a contrasting surface that allows scribed
lines to be seen clearly, improving cutting and machining accuracy.

, 5. Which metal property describes resistance to permanent
deformation under load?
A. Conductivity
B. Hardness
C. Density
D. Elasticity
Answer: B. Hardness
Rationale: Hardness measures resistance to indentation, scratching,
abrasion, and localized plastic deformation.
6. A fabrication drawing specifies ASTM A36 steel. This designation
primarily identifies the material's:
A. Paint color
B. Mechanical and chemical properties
C. Surface finish
D. Manufacturer
Answer: B. Mechanical and chemical properties
Rationale: ASTM A36 establishes minimum requirements for chemical
composition and mechanical properties of structural carbon steel.
7. Which welding process is generally preferred for high-speed
fabrication of mild steel using shielding gas and continuous wire
feed?
A. SMAW
B. GTAW
C. GMAW
D. Oxyfuel welding
3
, Answer: C. GMAW
Rationale: Gas Metal Arc Welding (MIG) offers high productivity,
continuous electrode feeding, and excellent efficiency for production
fabrication.
8. Excessive heat input during welding is most likely to cause:
A. Improved dimensional accuracy
B. Increased distortion
C. Lower electrical conductivity
D. Cleaner base metal
Answer: B. Increased distortion
Rationale: Heat causes uneven expansion and contraction, producing
warping, buckling, and residual stresses.
9. Before operating a hydraulic press brake, the technician should
first verify:
A. Radio station
B. Material color
C. Proper tooling installation and machine setup
D. Employee parking assignment
Answer: C. Proper tooling installation and machine setup
Rationale: Proper die selection, punch alignment, machine calibration,
and safety inspections are essential before bending operations.
10. What is the primary purpose of bend allowance calculations?
A. Determine paint thickness
B. Calculate material length required before bending
