Sheet Metal Fabrication Specialist Certification Exam Practice Questions And Correct Answers (Verified Answers) Plus Rationales 2026 Q&A | Instant Download Pdf

• What is the primary purpose of a sheet metal brake?
• To cut sheet metal
• To weld sheet metal
• To bend sheet metal
• To polish sheet metal

Rationale: A sheet metal brake is specifically designed to bend sheet

metal to precise angles.

• Which type of steel is commonly used in sheet metal fabrication for

corrosion resistance?

• Carbon steel 1 / 4

• Stainless steel
• Galvanized iron
• Cast iron

Rationale: Stainless steel contains chromium, which provides

corrosion resistance, making it ideal for fabrication.

• What is the standard unit of measurement for sheet metal thickness in

the United States?

• Centimeters
• Inches
• Meters
• Gauge

Rationale: Sheet metal thickness is commonly expressed in gauge,

where a higher gauge indicates thinner metal.

• Which cutting method produces the smoothest edge for sheet metal?
• Snips
• Shears
• Plasma cutting
• Laser cutting

Rationale: Laser cutting produces precise, clean edges with minimal

burrs.

• What is the main function of a rivet in sheet metal fabrication?
• To weld sheets together
• To cut sheets 2 / 4

• To fasten sheets together mechanically
• To polish sheets

Rationale: Rivets mechanically join two pieces of sheet metal without

welding.

6. In sheet metal terminology, “flanging” refers to:

• Cutting a sheet
• Bending the edge of a sheet to a right angle
• Polishing the sheet surface
• Drilling holes in a sheet

Rationale: Flanging is used to bend edges to strengthen or form a

connection.

• Which gas is commonly used in MIG welding sheet metal?
• Oxygen
• Hydrogen
• Argon
• Nitrogen

Rationale: Argon or argon mixes are commonly used as shielding

gases in MIG welding to prevent oxidation.

• What is the main hazard associated with sheet metal work?
• Electrical shock
• Cuts and lacerations
• Drowning
• Radiation exposure 3 / 4

Rationale: Handling sheet metal poses a high risk of cuts due to

sharp edges.

• What is a common method to join two pieces of sheet metal without

welding?

• Casting
• Riveting
• Melting
• Soldering only

Rationale: Riveting and mechanical fasteners allow joining without

heat.

• Which tool is used to create a round hole in sheet metal?
• File
• Chisel
• Punch
• Hammer

Rationale: Punches create precise holes by shearing metal through

die openings.

• What type of bend is formed when a sheet is bent less than 90

degrees?

• Flare
• Acute bend
• Right-angle bend
• / 4
