Preview Questions Welding Technician | Role Specific Skill

Question 1: How does "TIG (Tungsten Inert Gas) welding" differ from "MIG (Metal Inert Gas) welding" in terms of material application?

Which action should you take?

Choose only one option

TIG is best suited for thinner materials and provides more precise control, while MIG is ideal for thicker metals

TIG welding is faster than MIG welding and is used for general metal welding

MIG welding is used for high-precision applications and TIG is used for general applications

MIG welding provides more precise control, whereas TIG is only used for thick metals

Question 2: How does "preventive maintenance scheduling" help in ensuring the reliability of welding equipment?

Which action should you take?

Choose only one option

It reduces the risk of unexpected breakdowns and extends the lifespan of welding machines

It tracks only machine usage, ignoring the importance of preventive maintenance in preventing costly repairs

Preventive maintenance is unnecessary for reliable machine operation, as breakdowns are rare

Preventive maintenance adds unnecessary downtime to welding operations, reducing overall efficiency

Question 3: What is the main function of the welding machine's contactor switch?

Which action should you take?

Choose only one option

To maintain the required arc length during welding

To regulate the gas flow from the cylinder

To ensure proper shielding gas pressure

To control the power to the welding torch

Question 4: When conducting visual inspection, what indicates that a weld may be underfilled?

Which action should you take?

Choose only one option

The weld has no visible defects

The weld has excessive spatter

The weld surface is too high compared to the base material

The weld is flat or concave

Question 5: 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 6: If a welder notices porosity in the weld pool, what should be checked first?

Which action should you take?

Choose only one option

The machine's voltage settings

The filler metal composition and diameter

The shielding gas flow rate and purity

The arc length and torch angle
