Preview Questions Welding Technician | Role Specific Skill

Question 1: How do "electrode stick-out issues" affect the welding process and what is the remedy?

Which action should you take?

Choose only one option

It causes deeper penetration without any remedy required

It affects the arc length and increases spatter, which can be resolved by adjusting the electrode stick-out length

It improves arc stability, increasing the overall quality of the weld

It tracks only surface appearance and ignores the effect of stick-out on weld integrity

Question 2: How do "welding machine malfunctions" affect the welding process, and what steps can be taken to resolve them?

Which action should you take?

Choose only one option

Malfunctions always lead to stronger welds, requiring no corrective action

Machine malfunctions do not impact weld quality and should be ignored

Malfunctions can cause arc instability, poor penetration, and weak welds, and can be fixed by troubleshooting and repairing the machine

It tracks only machine downtime, ignoring the need for timely troubleshooting and repair

Question 3: What is the role of the root pass in quality control during welding inspection?

Which action should you take?

Choose only one option

To allow easy inspection of the final weld bead

To reduce the size of the weld and minimize the distortion

To ensure the base metal is properly fused to the filler material

To control the amount of spatter during the welding process

Question 4: What is the recommended minimum distance for welding in a confined space to ensure adequate ventilation?

Which action should you take?

Choose only one option

10 feet

15 feet

5 feet

3 feet

Question 5: What does "burnback" indicate in MIG welding and how can it be fixed?

Which action should you take?

Choose only one option

It tracks only the weld size, ignoring the role of proper settings in preventing burnback

Burnback is caused by contamination on the welding surface and can be fixed by cleaning the material

Burnback is a sign of poor shielding gas flow and can only be corrected by adjusting the gas flow rate

Burnback indicates that the wire is burning back into the nozzle and can be fixed by adjusting wire speed or reducing voltage

Question 6: 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
