Preview Questions Welding Technician | Role Specific Skill

Question 1: What is the first step in troubleshooting a welding machine that is not producing an arc?

Which action should you take?

Choose only one option

Change the electrode size to see if it resolves the issue

Check the power supply, ground clamp, and connections for issues

Increase the welding amperage and voltage

Inspect the shielding gas for contamination

Question 2: How do you fix an issue with a gas nozzle that is clogging too frequently?

Which action should you take?

Choose only one option

Replace the entire MIG gun assembly

Increase the gas flow pressure to compensate for clogging

Lower the amperage settings and use thinner filler wire

Clean the nozzle after every weld and replace it when necessary

Question 3: If a TIG welder starts making a high-pitched whistling sound, what should be checked?

Which action should you take?

Choose only one option

The water cooling system for obstructions

The condition of the TIG torch's gas nozzle and diffuser

The tungsten electrode diameter and type

The shielding gas flow and regulator pressure

Question 4: In welding inspection, what is the primary purpose of using magnetic particle testing (MT)?

Which action should you take?

Choose only one option

To identify the mechanical properties of the weld material

To detect surface and near-surface discontinuities in ferromagnetic materials

To measure the temperature of the weld during cooling

To assess the internal structure of the weld

Question 5: How do "welding fumes and gases" impact health, and how is exposure controlled?

Which action should you take?

Choose only one option

Fumes and gases are harmless as long as the work environment is well lit

Welding fumes are primarily composed of harmless particles, so exposure does not require protection

Welding fumes and gases can lead to long-term respiratory diseases, and proper ventilation and PPE are required

Exposure to welding fumes only impacts the visual quality of the weld and not worker health

Question 6: When inspecting welds for cracking, what is typically the first step in the process?

Which action should you take?

Choose only one option

Conducting ultrasonic testing for internal defects

Checking for visible surface cracks

Checking the hardness of the weld

Visual inspection for signs of stress and distortion
