Top 10 Questions for Auto Body Mechanic Apprentice Interview

1. What are the different types of welding used in auto body repair?

There are various types of welding used in auto body repair, some of the most common include:

• MIG (Metal Inert Gas) welding: Uses a consumable wire electrode in a shielding gas atmosphere.
• TIG (Tungsten Inert Gas) welding: Uses a non-consumable tungsten electrode and a shielding gas.
• Spot welding: Uses two electrodes to apply pressure and an electric current to fuse metal sheets together.
• Plasma welding: Utilizes a plasma arc to create a concentrated and precise heat source for welding.

2. How do you determine the severity of a collision damage?

Assessing Structural Damage

• Inspect the frame for any bends, cracks, or misalignments.
• Check for damage to the pillars, roof, and floor pan.

Evaluating Cosmetic Damage

• Assess the extent of dents, scratches, and paint damage.
• Determine if any panels need to be replaced or repaired.

3. What are the steps involved in replacing a quarter panel?

Replacing a quarter panel typically involves the following steps:

• Remove the old quarter panel by drilling out the spot welds or cutting it off.
• Prepare the new quarter panel by grinding and sanding the edges.
• Position the new quarter panel and secure it with temporary fasteners.
• Weld the new quarter panel in place using the appropriate welding technique.

4. How do you remove dents without damaging the paint?

There are several techniques to remove dents without damaging the paint:

• Paintless Dent Repair (PDR): Uses specialized tools to push the dent out from the inside.
• Heat Induction: Applies heat to the dented area to make the metal more malleable and easier to reshape.
• Dry Ice Method: Uses dry ice to rapidly cool the dented area, causing it to contract and pop back into shape.

5. What are the safety precautions you observe when working with auto body repair materials?

Important safety precautions in auto body repair include:

• Wearing appropriate personal protective equipment (PPE), such as gloves, safety glasses, and a respirator.
• Ensuring proper ventilation to prevent inhaling harmful fumes.
• Handling chemicals and solvents with care, following manufacturer’s instructions.
• Using proper grounding techniques when welding to prevent electrical shock.

6. Describe the process of refinishing a painted surface.

Refinishing a painted surface involves:

• Preparation: Sanding and cleaning the surface to remove imperfections and ensure proper adhesion.
• Priming: Applying a primer to create a smooth base for the paint.
• Painting: Applying multiple coats of paint to achieve the desired color and finish.
• Clear Coating: Applying a clear coat to protect the paint and provide a glossy finish.

7. What are the common causes of paint defects and how can they be prevented?

Common causes of paint defects include:

• Dust and Contaminants: Ensure a clean work environment and use tack cloths.
• Improper Surface Preparation: Sanding and cleaning the surface thoroughly helps prevent adhesion issues.
• Incorrect Paint Mixture: Follow manufacturer’s instructions for mixing ratios and application techniques.

8. How do you troubleshoot electrical issues in an automobile?

Troubleshooting electrical issues involves:

• Visual Inspection: Checking for damaged wires, loose connections, or blown fuses.
• Voltage Testing: Using a voltmeter to measure voltage at different points in the circuit.
• Circuit Tracing: Using a circuit diagram to follow the flow of electricity and locate the source of the problem.

9. What are the different types of auto body fillers and their applications?

Types of auto body fillers include:

• Polyester Filler: General-purpose filler for filling small to medium dents and holes.
• Epoxy Filler: High-strength filler for structural repairs and bonding different materials.
• Body Filler: Durable filler for filling larger areas and shaping surfaces.
• Glazing Putty: Fine-grained filler for smoothing out small imperfections and feathering edges.

10. How do you maintain and calibrate the equipment used in auto body repair?

Equipment maintenance includes:

• Regular Cleaning: Removing dust, debris, and paint residue from tools and equipment.
• Lubrication: Oiling moving parts to ensure smooth operation and prevent wear.
• Calibration: Using specialized equipment or techniques to adjust and verify the accuracy of measuring tools.
