Automotive Collision Repair: Ensuring Vehicle Safety After An Accident

 

Automotive Collision Repair

Current Collision Repair Trends

The automotive collision repair industry has undergone significant changes in the past decade. With advances in vehicle design and construction, collision repairs have become more complex. Vehicle bodies are now made with various lightweight metals and composite materials that require specialized tools and techniques to repair properly. Additionally, to enhance passenger safety, cars today have more airbags, reinforced passenger compartments, and advanced driver assistance systems. All of these modern safety features must be carefully inspected and recalibrated after an accident to ensure they function as designed in the event of a future crash.

Estimating Collision Damage

One of the primary tasks of any Automotive Collision Repair shop is to thoroughly estimate the damage to a vehicle involved in an accident. Experienced estimators will disassemble body panels, examine structural components, and carefully document all damaged or misaligned parts. High-resolution photos are also taken to create a permanent electronic record. Estimators then reference the original vehicle blueprints and specifications to determine exactly what parts need replacement and the labor hours required. Aftermarket and salvaged parts are considered, along with any manufacturer constraints. A written estimate is provided to insurance companies outlining all repairs and their projected costs. Additional supplements may be needed if hidden damage is uncovered during the repair process.

Repairing Vehicle Structures

The skeleton or "structure" of a vehicle forms the basis for its strength and safety performance. In a collision, structural components like frame rails, rocker panels, pillars and suspension mounts often sustain bending, twisting or crash deformation. Specialized frame machines allow technicians to precisely realign bent metal back to the vehicle's pre-accident geometry. Laser measurement systems are used to ensure dimensions are within factory specifications. In more severe cases, damaged sections may need to be sectioned and reinforced with welded steel inserts. Proper structural repair is critical before moving on to body and component replacement.

Replacing Exterior Panels in Automotive Collision Repair

With the vehicle structure repaired, body technicians turn their attention to replacing or repairing exterior panels. Modern steel is either bonded or welded into place depending on the material type and location. Large panels like hoods, doors and fenders often require blending of paint into adjacent areas for a seamless finish. Smaller trim, moldings and brightwork are meticulously removed, repaired as needed, and reinstalled. Any gaps between new and old panels are filled using body filler and sanded down to a smooth surface ready for primer. Specialized equipment like pneumatic air wrenches and dent extraction tools help remove and install parts quickly and accurately.

Upgrading Vehicle Components

In addition to structural reinforcement and new body panels, a collision repair involves replacing dozens of smaller related components that may have been damaged or have to be removed to access other areas. This can include items like bumper covers, headlights, taillights, emblems and trim pieces. It also involves reattaching crucial vehicle systems. For example, repairing airbags requires disconnection and deployment of inflators before installation of new units. Electronics have to be verified to function properly, including communication between modules. Repairs to braking, steering and suspension components ensure the vehicle's dynamics are restored as intended by the manufacturer. Thorough testing validates all repairs before return to the customer.

Refinishing Vehicle Exteriors

Regardless of the extent of bodywork performed, nearly every collision repair requires some level of refinishing to the vehicle's exterior. Once body panels and trim are replaced and surfaces are filled and sanded, a few steps of priming and sealing help prepare the substrate for paint. High-quality automotive paint is then applied using robotic sprayers in a controlled paint booth environment. Multiple coats of both color and clear coat are typically needed to achieve the manufacturer's paint thickness specifications. After painting is complete, the vehicle moves to a bake oven, then is polished and polished to restore an impeccable factory finish. Proper paint matching and matching is critical for a seamless repair.

Ensuring Quality Assurance in Automotive Collision Repair

The final and arguably most important steps in any collision repair involve quality assurance testing before returning the vehicle to the customer. Thorough inspections using laser measurements, frame gauges and other diagnostic tools verify that all structural, mechanical and cosmetic aspects of the repair meet factory specifications and fit/finish standards. If needed, corrections are made. Road tests are performed to check braking, steering, suspension and drivability. Functional testing validates that all electrical components, sensors and driver assist systems perform as designed. A careful walkaround inspection catches any missed defects before completion. Proper documentation of the full repair process provides a permanent record and builds confidence in the shop's workmanship.

the goal of any professional automotive collision repair facility is to completely restore a damaged vehicle to its pre-accident condition using factory-approved procedures, high-quality OEM replacement parts, and stringent quality assurance testing. As vehicles become even more advanced, the skills and training required of today's collision technicians will continue to evolve. Consumers can feel assured entrusting repairs to experienced I-CAR trained shops that focus on safety, structural integrity and an invisible finished product.
