Summarized Exam Coverage – NYC Auto Body Worker
The NYC Auto Body Worker exam covers metal straightening and repair techniques (hammer/dolly,
pulling, shrinking), welding and cutting (oxy-acetylene, MIG, spot welding – including FDNY G-60 hot
work safety principles), body panel replacement and alignment, filler and finishing (body filler
application, sanding, priming), glass and trim removal/installation, vehicle modification (police/fleet
upfitting), structural sectioning and welding of heavy truck, bus, and auto frames, corrosion repair, use
of shop equipment (frame machines, welders, grinders), and safety practices (fire prevention,
– NYC Auto Body Worker Exam
1. You are repairing a damaged rear quarter panel on a NYC fleet sedan. After straightening the metal,
you notice a small high spot. What tool should you use to shrink the stretched metal without causing
further distortion?
A) Body file
B) Heat shrink tip on a stud welder or oxy-acetylene torch followed by quenching

C) Coarse grit sandpaper on a DA sander
D) Slapping file
Answer: B — Shrinking requires localized heat and rapid cooling to contract stretched metal; a shrinking
tip or torch method is standard for high spots.
2. While using an oxy-acetylene torch to cut a damaged frame section, the flame pops and goes out. You
must hold an FDNY G-60 Certificate of Fitness for torch use. What is the first thing you should check?
A) The oxygen cylinder pressure only
B) The flashback arrestors and check valve operation
C) The color of the work gloves
D) The ground clamp connection
Answer: B — Flashback arrestors prevent flames from traveling back into hoses and cylinders; popping
can indicate a flashback or blocked tip.
3. A fleet van requires a full rear frame section replacement. You must weld the new section using MIG.
What gas mixture is most commonly used for MIG welding automotive sheet metal and structural steel?
A) 100% Argon
B) 75% Argon / 25% CO2 (C25)

C) 100% CO2
D) 100% Oxygen
Answer: B — C25 provides good penetration with minimal spatter and is the industry standard for mild
steel MIG welding in auto body repair.
4. Your supervisor asks you to straighten a front rail on a NYPD vehicle. The rail is made of high-strength
steel (HSS). What is the most important precaution before applying heat or pulling force?
A) Heat the rail to cherry red before pulling
B) Follow manufacturer cold-straightening specifications; HSS can weaken if heated
C) Use a rosebud tip to soften the metal first
D) Weld reinforcing plates before pulling
Answer: B — High-strength steels lose strength when heated; Many manufacturers prohibit heat
straightening and require cold pulling or replacement.
5. During a NYC vehicle modification, you must cut a hole in the roof for an emergency light. What tool
provides the cleanest, most precise cut with minimal distortion?
A) Plasma cutter
B) Oxy-acetylene torch

C) Pneumatic body saw (nibbler)
D) Angle grinder with cutoff wheel
Answer: C — A body saw (nibbler) or reciprocating saw with fine blade creates precise cuts with minimal
heat distortion compared to torches or plasma.
6. You are removing spot welds to replace a damaged door skin. What type of drill bit is specifically
designed to remove spot welds without cutting through the base panel?
A) Standard twist drill bit
B) Spot weld cutter (rotary broach type)
C) Masonry bit
D) Step drill bit
Answer: B — Spot weld cutters have a pilot and cutting teeth that separate the top panel without
damaging the underlying metal.
7. After applying body filler to a repaired panel, you notice pinholes in the finished surface after sanding.
What is the most likely cause during mixing?
A) Too much hardener added
B) Air bubbles introduced by improper mixing technique (stirring vs. folding)
