Preview Questions Welding Technician | Role Specific Skill

Question 1: How often should a welding machine's internal components be inspected for wear and tear?

Which action should you take?

Choose only one option

After every 50 hours of usage

Once every year

Every 3 months

Every 6 months

Question 2: How would you resolve a problem where the welding machine is tripping the circuit breaker during operation?

Which action should you take?

Choose only one option

Use a larger electrode to spread the current load

Check for short circuits, damaged cables, or improper grounding

Replace the power supply without checking the settings

Increase the amperage setting to reduce current draw

Question 3: What is the significance of "weld fatigue" and how is it related to quality control?

Which action should you take?

Choose only one option

Weld fatigue is unrelated to weld quality and does not require monitoring

Weld fatigue occurs only in high-temperature environments and is evaluated by temperature testing

Weld fatigue is a visual defect that can be detected during the inspection process

Weld fatigue refers to the weakening of the material due to repetitive loading cycles, and is evaluated by fatigue testing

Question 4: What is the purpose of wearing a flame-resistant jacket while welding?

Which action should you take?

Choose only one option

To improve welding visibility

To reduce the chances of burns from hot metal splatter

To protect against UV radiation from the welding arc

To ensure full body protection against electrical hazards

Question 5: What is the purpose of a fillet weld throat dimension measurement during inspection?

Which action should you take?

Choose only one option

To evaluate the uniformity of the weld bead

To ensure the weld meets the minimum size for strength and load-bearing capacity

To measure the depth of penetration in the base material

To determine the correct spacing between the weld and the material

Question 6: In MIG welding, what is the most critical factor to control for optimal bead formation?

Which action should you take?

Choose only one option

Electrode angle

Voltage and wire feed speed

Arc length only

Gas flow rate
