1. Before striking an arc, what is the most important reason for inspecting welding cables and
electrode holders?
A. To improve weld appearance
B. To reduce electrode consumption
C. To prevent electrical hazards and equipment failure
D. To increase welding speed
════════════════════
Correct Answer: C. To prevent electrical hazards and equipment failure
Rationale:
Damaged cables and faulty electrode holders can expose workers to electrical shock, fires,
and equipment malfunction. Safety inspections before welding are essential for protecting
both personnel and equipment.
════════════════════
2. Which personal protective equipment is specifically designed to protect a welder's eyes
from ultraviolet radiation?
A. Welding helmet with the correct shade lens
B. Ear plugs
C. Leather gloves
D. Safety boots
════════════════════
Correct Answer: A. Welding helmet with the correct shade lens
Rationale:
A welding helmet equipped with an appropriate filter lens protects the eyes from harmful
ultraviolet and infrared radiation generated by the welding arc. The other items protect
different areas of the body but not the eyes.
════════════════════
3. What is the primary purpose of slag when using shielded metal arc welding (SMAW)?
,A. Increase electrical conductivity
B. Improve travel speed
C. Protect the molten weld from contamination during cooling
D. Decrease weld penetration
════════════════════
Correct Answer: C. Protect the molten weld from contamination during cooling
Rationale:
Slag forms a protective covering over the molten weld metal, preventing atmospheric
contamination and assisting in controlled cooling. It does not increase conductivity or reduce
penetration.
════════════════════
4. A welder notices grease and paint on a steel plate before welding. What should be done
first?
A. Increase amperage
B. Apply additional filler metal
C. Strike the arc immediately
D. Clean the surface thoroughly
════════════════════
Correct Answer: D. Clean the surface thoroughly
Rationale:
Contaminants such as grease, rust, and paint can cause porosity and other weld defects.
Proper surface preparation is essential for producing sound welds.
════════════════════
5. Which type of fire extinguisher is generally suitable for electrical fires in a welding shop?
A. Class C extinguisher
B. Class A extinguisher
C. Water hose
D. Sand only
════════════════════
Correct Answer: A. Class C extinguisher
Rationale:
,Class C extinguishers are intended for energized electrical equipment fires. Water should
never be applied to electrical fires because it can conduct electricity and increase hazards.
════════════════════
6. During SMAW, excessive electrode sticking commonly indicates that the welding current is:
A. Too high
B. Too low
C. Perfectly adjusted
D. Alternating excessively
════════════════════
Correct Answer: B. Too low
Rationale:
Insufficient current makes it difficult to maintain a stable arc and often causes the electrode to
stick to the workpiece. Proper amperage produces smoother arc characteristics.
════════════════════
7. Which hand tool is commonly used to remove slag after completing a weld bead?
A. Ball-peen hammer
B. Combination square
C. Pipe wrench
D. Chipping hammer
════════════════════
Correct Answer: D. Chipping hammer
Rationale:
A chipping hammer is specifically designed to remove slag deposits from completed welds.
Other tools serve different functions and are less effective for slag removal.
════════════════════
8. Why is adequate ventilation important during welding operations?
A. It improves electrode storage
B. It reduces exposure to hazardous fumes and gases
C. It lowers metal hardness
D. It increases penetration
, ════════════════════
Correct Answer: B. It reduces exposure to hazardous fumes and gases
Rationale:
Welding generates fumes and gases that can be harmful when inhaled. Proper ventilation
helps maintain air quality and protects worker health.
════════════════════
9. What does the term "base metal" refer to in welding?
A. The flux coating
B. The filler metal
C. The metal being joined
D. The slag covering
════════════════════
Correct Answer: C. The metal being joined
Rationale:
Base metal is the material that is being welded together. Understanding the properties of the
base metal is essential for selecting procedures and filler materials.
════════════════════
10. Which position places the weld on the upper side of a horizontal surface?
A. Vertical position
B. Overhead position
C. Horizontal position
D. Flat position
════════════════════
Correct Answer: D. Flat position
Rationale:
The flat position places the weld on the upper surface of the joint, allowing gravity to assist
weld deposition and making it generally the easiest welding position.
════════════════════
11. What is the principal function of welding gloves?
