ASE Structural Analysis & Damage Repair 3

Question 1

When sectioning a frame rail, the location of the cut should be guided primarily by:

Accepted Answer

Vehicle maker's recommended sectioning procedures

Answer

Manufacturer procedures specify acceptable sectioning locations to preserve structural integrity.

Question 2

Which welding process is most commonly recommended for collision repair of modern steel unibody structures?

Accepted Answer

GMAW (MIG) welding

Answer

GMAW/MIG welding provides controlled heat and strong welds suited to thin structural steel.

Question 3

Excessive heat applied to high-strength steel during repair will:

Accepted Answer

Reduce its strength by altering the metallurgy

Answer

Heat above recommended limits anneals high-strength steel and weakens it.

Question 4

Corrosion protection must be reapplied after structural welding because:

Accepted Answer

Welding burns away the original anti-corrosion coatings

Answer

Welding heat destroys factory corrosion coatings, so they must be restored to prevent rust.

Question 5

A plug weld used in panel replacement is created by:

Accepted Answer

Welding through a pre-drilled or punched hole to join two layers

Answer

A plug weld fills a punched hole to fuse the top panel to the one beneath, simulating a spot weld.
