Which technique joins metal pieces using rivets driven through aligned holes?

• A. Soldering
• B. Brazing
• C. Welding
• D. Riveting

Answer: (D)

This is about a fastening method that creates a joint by passing a rivet through holes in the pieces and deforming the rivet to form a second head on the opposite side. The head on one end and the deformed tail grip the parts together, clamping them firmly without melting the metal. The strength comes from the rivet bearing against the hole walls and being driven to pinch the metals together, so loads are carried in shear through the rivet rather than by fusing the pieces.

Soldering, brazing, and welding involve melting or flowing filler metal to join parts or fusion of the base metal. They don’t rely on a mechanical pin driven through aligned holes to hold pieces together, which is why riviting is the correct choice here. Blind rivets and solid rivets are common types, with blind rivets usable from one side and solid rivets requiring access to both sides for deformation.
