Preview Questions Welding Technician | Role Specific Skill

Question 1: Which standard governs the safe use of welding equipment in the workplace?

Which action should you take?

Choose only one option

ASME Section IX

ISO 9001

OSHA 1910.252

NFPA 70E

Question 2: 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 3: What inspection method is used to measure the size of internal voids or porosity in a weld?

Which action should you take?

Choose only one option

Ultrasonic Testing (UT)

Magnetic Particle Inspection (MPI)

X-ray or Radiographic Testing (RT)

Visual Inspection (VT)

Question 4: How does "incorrect polarity" affect the weld, and how can it be fixed?

Which action should you take?

Choose only one option

It tracks only the electrode position, ignoring the importance of adjusting polarity during welding

Correct polarity improves only the visual appearance of the weld without affecting its strength

Incorrect polarity leads to poor fusion and excessive spatter, which can be fixed by adjusting the machine's polarity settings

Polarity does not affect weld quality and should be ignored during the welding process

Question 5: In stick welding (SMAW), what is the main factor that controls the size and shape of the weld bead?

Which action should you take?

Choose only one option

The voltage alone

The amperage, electrode size, and travel speed

The angle of the electrode relative to the workpiece

The type of electrode used

Question 6: How do you control the penetration depth in a TIG welding process?

Which action should you take?

Choose only one option

By using higher amperage only

By adjusting the shielding gas flow rate

By adjusting the current and controlling the arc length

By changing the filler rod size
