ASA 106 FINAL EXAMINATION
CURRENTLY TESTING MOST EXAM
QUESTIONS WILL COME FROM HERE
UPDATED THIS YEAR /ALREADY GRADED
A+
1.
A technician is welding inside a partially enclosed steel
structure and begins feeling lightheaded after several
minutes. What is the most appropriate immediate action?
A. Continue welding to finish quickly
B. Sit down and reduce welding speed
C. Stop work immediately and move to fresh air
D. Drink water and continue working
Answer: C
Rationale: Lightheadedness indicates hazardous fume
buildup or oxygen deficiency requiring immediate
evacuation.
2.
,A welder discovers that the welding machine is not
properly grounded before starting work on a steel frame.
What should be done first?
A. Begin welding carefully with gloves
B. Report and correct grounding before operation
C. Reduce voltage and proceed
D. Tape the grounding wire temporarily
Answer: B
Rationale: Improper grounding creates electrocution risk
and must be corrected before use.
3.
During fabrication, a steel beam bends unexpectedly after
welding due to uneven heating. What is the most likely
cause?
A. Proper cooling rate
B. Excessive and uneven heat input during welding
C. Correct joint design
D. Proper electrode storage
Answer: B
Rationale: Uneven heat distribution causes thermal
distortion and warping.
,4.
A trainee misreads a welding symbol on a blueprint and
applies the wrong weld type. What is the most serious
consequence?
A. Slight improvement in weld speed
B. Reduced production cost
C. Structural weakness or failure
D. Improved aesthetic appearance
Answer: C
Rationale: Incorrect weld type compromises structural
integrity.
5.
A fabricator cuts a steel plate too short due to incorrect
measurement interpretation. What principle was violated?
A. Welding heat control
B. Dimensional accuracy and tolerance compliance
C. Corrosion prevention
D. Electrode selection
Answer: B
Rationale: Accurate measurement is essential for proper
fabrication fit-up.
, 6.
A weld shows excessive spatter and poor penetration
during inspection. What is the most likely cause?
A. Correct shielding gas usage
B. Improper welding parameters such as voltage or travel
speed
C. Proper electrode selection
D. Clean base metal
Answer: B
Rationale: Incorrect welding settings directly affect weld
quality.
7.
A finished weld contains porosity bubbles visible on the
surface. What is the most likely cause?
A. Proper arc length control
B. Contaminated base metal or insufficient shielding gas
C. Correct electrode angle
D. Proper cooling time
Answer: B
Rationale: Porosity is caused by contamination or poor
shielding.
