ASE Practice Test (B4: Structural Analysis & Damage Repair)

Question 1

A unibody vehicle has been in a front-end collision. Before beginning structural repairs, the technician should FIRST:

Accepted Answer

Perform a complete three-dimensional measurement of the vehicle

Answer

Begin pulling the damage with the frame rack

Answer

Replace all visibly damaged structural components

Answer

Check the door gaps and wheel alignment

Question 2

High-strength steel (HSS) and ultra-high-strength steel (UHSS) require special consideration during repairs because:

Accepted Answer

Heat application can reduce their strength below original specifications

Answer

They are more prone to rust than conventional mild steel

Answer

They cannot be welded using MIG welding equipment

Answer

They require special paint primers not compatible with urethane topcoats

Question 3

A vehicle's datum plane measurement is out of specification by 15mm at the rear. This indicates:

Accepted Answer

The vehicle has twist damage in the structure

Answer

The vehicle has side sway damage

Answer

The vehicle has diamond damage

Answer

The vehicle has sag damage in the rear section

Question 4

When sectioning a structural rail, the splice joint must be located:

Accepted Answer

In an area specified by the vehicle manufacturer, away from bends and stress risers

Answer

At the closest point to the damaged area for minimal material waste

Answer

At the center of the damaged rail section

Answer

As close to a factory weld as possible to maintain original geometry

Question 5

A vehicle shows mash damage after a frontal collision. This type of structural damage is characterized by:

Accepted Answer

The front rails being compressed shorter than OEM specifications

Answer

The front structure being pushed to one side

Answer

The front rails being bent downward below the datum plane

Answer

The engine cradle being rotated out of its original plane

Question 6

Squeeze-type resistance spot welding (STRSW) is preferred over MIG plug welding for structural repairs because:

Accepted Answer

STRSW more closely replicates the factory weld quality and heat-affected zone

Answer

STRSW is less expensive and requires no special equipment

Answer

MIG plug welding introduces too much filler metal into the joint

Answer

STRSW can be used on all grades of steel including UHSS
