existing spot welds.Technician B says that single-sided spot welding is generally recommended.
Who is right? - ANS-Neither A nor B
Technician A says that removing seam sealer may help exposed hidden spot welds.Technician
B says that vehicle-specific service information may provide spot weld loca-tions.Who is right? -
ANS-Both A and B
All of these are designed to be used for removing spot welds EXCEPT a: - ANS-reciprocating
saw.
Technician A says that radiator core supports may have a different look, but all have upper and
lower tie bars and side supports.Technician B says that a radiator core support may be bolted
on.Who is right? - ANS-B only
Which of these may be a strengthened area in a rail? - ANS-An inner reinforcement
Technician A says that replacement of the rear rail may involve removal of the fuel tank.

Who is right? - ANS-Both A and B
All of these are true about floor assembly crossmembers EXCEPT they: - ANS-are usually
stamped into the floor pan.
Technician A says that rear rails may be closed out on the end by the rear body
panel.Technician B says that cutting an access hole in the trunk floor to assist with straightening
is considered sectioning.Who is right? - ANS-Both A and B
Which flat area of a strut tower assembly may be able to be straightened? - ANS-Apron panel,
forward of the strut tower
, Technician A says that an inner rail may be supplied as a separate replacement part. Technician
B says that convoluted areas on a rail should be reinforced with inserts. Who is right? - ANS-A
only
Technician A says that a floor pan may have convolutions, similar to rails. Technician B says
that a floor pan may have extra-strength areas, similar to rails. Who is right? - ANS-Both A and
B
All of these may be recommended for making a seam weld along a sectioning joint EXCEPT: -
ANS-spot welds.

right? - ANS-B only

Tack welds: - ANS-can be used to hold parts in position for proper joint fit-up.
Technician A says that one reason for notching the pinchweld flanges with a flanged lap joint is
to allow the weatherstripping to fit.Technician B says that a flanged lap joint requires a backing
on the pinchweld flanges. Who is right? - ANS-A only
Technician A says that if weld-through primer is applied to a weld area, it should be removed
from the specific site where the weld will be made.Technician B says that some vehicle makers
