Structural Analysis & Damage Repair Flashcards

After a structural repair, checking wheel alignment and tracking is important because:

Answer: Structural shifts affect suspension and steering geometry

Structural displacement changes mounting points, so alignment must be verified after repair.

Which document is the most authoritative source for structural repair procedures on a specific vehicle?

Answer: The vehicle manufacturer's body repair manual

OEM body repair manuals provide the validated, vehicle-specific structural repair procedures.

Boron steel components in modern vehicles are difficult to repair because they are:

Answer: Ultra-high-strength and typically must be replaced, not straightened

Boron (ultra-high-strength) steel cannot be straightened and is replaced per OEM procedures.

When repairing aluminum structural components, technicians must use a separate isolated work area mainly to:

Answer: Prevent steel dust contamination that causes galvanic corrosion

Isolating aluminum work prevents steel particles from embedding and causing galvanic corrosion.

A pull that over-corrects the damage should be handled by:

Answer: Releasing and re-pulling to bring it back to exact spec

Over-corrected structure must be brought precisely back to factory dimensions, not left or hidden.

Before final welding of a replacement structural panel, the technician should verify:

Answer: That all dimensional measurements are within spec

Dimensions must be confirmed within spec before welding so the panel is fixed in the correct position.

A weld-through primer is applied to mating flanges before welding in order to:

Answer: Provide corrosion protection at the joint that welding heat tolerates

Weld-through primer protects the inaccessible joint area from corrosion while allowing welding through it.
