The _____________ structural assembly on the unibody consists of the core support, upper and lower side rails and the strut tower.

Answer 3

front

Question 4

Technician A says the manufacturer uses crush zones to help manage the collision energy . Technician B says a disadvantage of using recycled parts is they must be separated individually in order to use the part often damaging the part that is needed. Who is correct?

A) A only
B) B only
C) Both A and B
D) Neither A nor B

Question 5

Technician A says placing seams at suspension mounting locations should be avoided when making a sectional replacement. Technician B says plug welds are used to hold the insert into place when a butt joint with insert is used. Who is correct?

A) A only
B) B only
C) Both A and B
D) Neither A nor B

Question 6

Technician A says STRSW is commonly used to install replacemet parts because it creates less heat than other welding processes. Technician B says placing a seam in a crush zone will not affect the timing of an air bag deployment. Who is correct?

A) A only
B) B only
C) Both A and B
D) Neither A nor B

Question 7

Advanced high strength steel reinforcements are commonly used around the ______________ compartment.

Question 8

Technician A says the Bend vs. Kink rule is as applicable for advanced high strength steel repairs as it is for mild steel. Technician B says resistance spot welding is a common practice when replacing structural parts. Who is correct?

A) A only
B) B only
C) Both A and B
D) Neither A nor B

Question 9

Technician A says repair blueprinting involves using the manufacturers original design to restore the vehcile to its pre-collision condition. Technician B says some manufacturers use different grade of steel at the lower part of the B pillar to allow for performing a sectional replacement. Who is correct?

A) A only
B) B only
C) Both A and B
D) Neither A nor B

Question 10

The ____________________ frame is commonly made of high strength steel and must be treated as such.

Question 11

The manufacturer occasionally covers the spot welds with a seam sealer to disguise them making the area more asthetically appealing.

Question 12

Technician A says the B pillar opening must be restored dimensionally before removing the damaged parts even though they are going to be replaced. Technician B says a disadvantage of making a sectional replacement is that it requires more disassembling of the vehicle. Who is correct?

A) A only
B) B only
C) Both A and B
D) Neither A nor B

Question 13

Technician A says the hat channel is used on the C pillar for reinforcement when replacing the quarter panel. Technician B says the tapered lap joint is used commonly used whenever there is a long smooth and uninterrupted smooth surface of the rail. Who is correct?

A) A only
B) B only
C) Both A and B
D) Neither A nor B

Question 14

A hat channel is commonly used for reinforcing various structural parts.

Question 15

Technician A says performing a continuous seam weld when MIG welding a replacement part into place is the manufacturers preferred method. Technician B says manufacturers spot welds are always replaced one for one with MIG plug welds when replacing structural parts. Who is correct?

A) A only
B) B only
C) Both A and B
D) Neither a nor B

Question 16

When making a sectional replacement through a taylor welded joint one should make the weld seam using stitch welds.

Question 17

The MPa rating of advanced high strength steel parts ranges from _________ to ________.

Question 18

The root gap is the area between the two edges that are to be welded together, securing the replacement rail to the existing one on the vehicle.

Question 19

Technician A says High Strength Steel is commonly used for parts that are hydroformed. Technician B says some manufacturers use taylor rolled blanks at the outer end of the rail to protect the rail deeper into the vehicle and to help absorb some of the collision energy. Who is correct?

A) A only
B) B only
C) Both A and B
D) Neither A nor B

Question 20

Both the trunk floor and the passenger compartment floor have convolutions stamped into them for reinforcement.

Question 21

Discuss what is meant by a uniside panel.

Question 22

Discuss why many of the panel reinforcements must be replaced on most late model vehicles as opposed to straightening them.

Question 23

Discuss what is meant by laminating parts.

Question 24

Discuss the difference between taylor welded blanks and taylor rolled blanks.

Question 25

Explain the process of die stamping.
