Preview Questions Welding Technician | Role Specific Skill

Question 1: How does "welding machine grounding" affect the safety and efficiency of welding operations?

Which action should you take?

Choose only one option

Grounding is necessary only to prevent machine overheating and not for operational safety

Grounding does not significantly affect welding efficiency and is only for electrical shock prevention

Proper grounding ensures safe operation and prevents electrical shock and damage to the machine

It tracks only welding arc quality, ignoring the importance of grounding in protecting the operator

Question 2: What type of protective gear should be worn when performing arc welding with flux?

Which action should you take?

Choose only one option

Helmet with a protective lens, gloves, and full-body suit

Safety goggles and leather gloves

Welding helmet, gloves, and flame-resistant apron

Full-face shield, gloves, and welding boots

Question 3: What is the effect of using an improper shielding gas mixture during welding?

Which action should you take?

Choose only one option

It can result in poor weld quality, porosity, and oxidation of the weld

It reduces the amount of heat required to weld materials

It enhances the appearance of the weld but not the strength

It increases the welding speed and reduces material usage

Question 4: How do "working at height" safety procedures apply to welding technicians?

Which action should you take?

Choose only one option

Fall protection is unnecessary if welding is done on scaffolding and not directly overhead

Working at height safety is not required for welding unless a ladder is used for inspection purposes

Working at height procedures do not apply if welding is done at ground level

They include fall protection measures and ensuring secure platforms, reducing the risk of injury while welding at height

Question 5: How should compressed gas regulators be handled to ensure safe operation during welding?

Which action should you take?

Choose only one option

Leave regulators attached to cylinders when not in use

Ensure they are securely attached and set at the correct pressure before use

Use regulators without checking for leaks

Set the pressure as high as possible to avoid fluctuations

Question 6: What is "slag inclusion" in welding and how can it be avoided?

Which action should you take?

Choose only one option

It improves the final weld strength, increasing its durability

Slag inclusion occurs when slag is trapped in the weld, weakening the joint, and can be avoided by proper cleaning and using the correct welding parameters

Slag inclusion is a result of over-welding and cannot be avoided

It tracks only the aesthetic quality, ignoring the negative impact of slag on structural integrity
