Deck 16: Structural Parts Replacement

Question 1

Technician A says an insert will help to strengthen the area where the joint is welded. Technician B says increasing the number of MIG plug welds that the manufacturer used may alter the vehicle's ability to distribute the impact forces in a subsequent collision. Who is correct?

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

Answer 1

C

Question 2

Technician A says the quarter and back glass must be removed when replacing the quarter panel. Technician B says that a spot weld nugget is the name for a perfectly executed weld. Who is correct?

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

Answer 2

A

Question 3

Technician A says A lap joint is commonly used on trunk floors and passenger compartment floor pans. Technician B says weld bonding requires less corrosion protection and will help to reduce vehicle NVH. Who is correct?

A) A only
B) B only
C) Both A and B
D) Nether A nor B

Answer 3

C

Question 4

Some manufacturers may require the use of an open butt joint when installing exterior panels while others may specify a butt joint with insert or backer.

Question 5

Technician A says weld bonding can be used on all structural panels, provided adequate curing time is allowed. Technician B says an insert or a sleeve used in a sectional replacement will reinforce the seam area, so it is as strong as the original rail was. Who is correct?

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

Question 6

A ____________________ bulletin is an update of information by the manufacturer which usually supersedes the repair manual.

Question 7

UPCR is a series of guidelines developed by I-CAR through a very extensive testing process, which provides recommended procedures for the collision repair technician to follow when replacing both structural and non-structural panels and reinforcements on vehicles.

Question 8

Technician A says a stitch weld technique should be used when welding the seam to minimize the possibility of warpage. Technician B says that when drilling out spot welds, one should drill through both surfaces, Who is correct?

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

Question 9

Technician A says Some exterior body panels must be replaced at the factory seams. Technician B says the size of the root gap is determined by the metal thickness where the weld is being made. Who is correct?

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

Question 10

A piece of metal that is welded to a damaged panel and used to pull the damage out of the surface, in an effort to restore the proper configuration, is called a ____________________ tab or sweat tab.

Question 11

The distance or gap between the two edges of the metal that is to be welded together is called the ____________________ gap.

Question 12

Technician A says that the "A" pillar is the attaching point for the shoulder belt. Technician B says that TIG welding is the best form of weld bonding. Who is correct?

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

Question 13

Technician A says using a flameless heating device can be used to soften the adhesive making removal easier. Technician B says when welding the replacement panel into place, the technician should make the first welds on the definition crowns. Who is correct?

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

Question 14

A process where water or hydraulic fluid or another liquid is used under extremely high pressure to finish forming structural parts by placing the part into a mold and filling the rail and subjecting it to pressure, is called hydro-forming.

Question 15

Silicone ____________________ is a welding filler that melts at a relatively low temperature, resulting in a minimum amount of warpage when welding, particularly in areas such as the sail panel, where a large amount of filler is required for filling a seam.

Question 16

LKQ stands for Like Kind and Quantity.

Question 17

Technician A says using the air hammer will separate the metal surfaces more quickly and more cleanly than drilling the spot welds first. Technician B says sectioning panels can be done in the areas of the quarter panel and the trunk floor pan. Who is correct?

A) A only
B) B only
C) Both A and B
D) Neither A and B

Question 18

Prior to installing a replacement part onto a vehicle, the edges and underside of the panel should be painted to match the color of the vehicle. This process is called jamming and edging.

Question 19

____________________ is a method of attaching a replacement panel such as a roof, which incorporates the use of both adhesives and welding to ensure structural integrity has been restored to the repair area and the overall vehicle.

Question 20

Technician A says that MIG welding uses a welding filler that melts at a relatively low temperature,resulting in a minimum amount of warpage when welding, particularly in areas such as the sail panel where a large amount of filler is required for filling a seam. Technician B says that during welding, the area immediately around the weld site that may become slightly weaker from the effects of the heat is the heat affect zone. Who is correct?

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

Question 21

Explain the system of "Bag and Tag".

Question 22

What is partial panel replacement?

Question 23

Explain the significance of the heat affect zone in welding operations.

Question 24

What is the belt line?

Question 25

Describe a uniside panel.
