Identify the false statement about riveting of two plates together

Explanation:

Caulking:

• Caulking is an operation of closing down the edges of the plates and heads of the rivets to form a metal-to-metal joint.
• The edge of the rivet head is tightly pressed and expanded on the plate by a caulking tool that looks like a fattened cold chisel.

Fullering:

• Fullering is an operation of pressing the whole surface of the edge of the plate.
• It is done by a fullering tool.
• When the caulking tool is about as thick as the plate, it is called a fullering tool.
• The whole surface of the edge of the first plate is tightly pressed on the second plate.
• A better fluid-tight joint is achieved by fullering.
• Caulking is done on the edges of the plates as well as on the edges of the rivet heads.
• But fullering is done on the edges of the plate only.
• To facilitate caulking and fullering on the plates, the edges of the plates are bevelled about 80° to 85°.
