Preview Questions Welding Technician | Role Specific Skill

Question 1: What safety measure should be followed when using compressed gas cylinders in welding?

Which action should you take?

Choose only one option

Only use cylinders that are older than 10 years

Store cylinders horizontally to save space

Ensure cylinders are properly secured and stored upright

Only use cylinders indoors to prevent temperature fluctuations

Question 2: How does "welding machine calibration" differ for different welding processes (e.g., TIG vs. MIG)?

Which action should you take?

Choose only one option

Calibration settings vary based on the type of welding process to optimize performance and material fusion

Calibration is identical for all welding processes and does not require adjustment based on the process type

Calibration only affects the visual appearance of the weld, not the welding process itself

Calibration is not necessary for MIG or TIG welding, as both processes use the same settings

Question 3: What is the primary purpose of inspecting the welding machine's power cables and connections?

Which action should you take?

Choose only one option

To minimize the amount of power consumed by the machine

To ensure proper electrical conductivity and prevent overheating

To ensure that the machine operates at maximum efficiency

To increase the power of the welding machine

Question 4: What is the effect of welding with incorrect gas flow rates?

Which action should you take?

Choose only one option

It stabilizes the arc and reduces the heat input

It reduces the amount of fumes and sparks generated

It can lead to poor shielding, resulting in contamination, oxidation, and weld defects

It improves the speed of the weld without affecting quality

Question 5: In ultrasonic testing, what is the purpose of the coupling agent?

Which action should you take?

Choose only one option

To amplify the sound waves

To reduce the reflection of sound waves

To prevent the weld from overheating during the test

To ensure the probe makes good contact with the material

Question 6: How does "electrical circuit inspection" impact welding machine performance?

Which action should you take?

Choose only one option

It ensures that all connections are intact, preventing voltage fluctuations and ensuring stable welding conditions

Circuit inspection only matters for machines with visible electrical damage and does not affect operation

Electrical circuit inspection is not necessary unless the machine stops working entirely

It tracks only aesthetic quality and does not affect electrical performance
