Rivet Sheet Metal Joints Flashcards
What is the minimum edge distance allowed when installing rivets in a piece of aircraft sheet metal structure?
Two times the diameter of the rivet shank
What is the recommended transverse pitch to use when making a riveted two row splice in a piece of sheet metal?
Threr-fourths of the distance between the rivets in the row
Why should aluminum alloy rivets be driven with a few blows ad is practical?
Excessive hammering will work-harden the rivets and make them difficult to drive
What determines whether a piece of sheet metal should be dimpled or countersunk when installing flush rivets?
The thickness of the sheet. Counter sinking should be done only when the thickness of the sheet is greater than the thickness of the rivet head
What type of metal should be hot-dompled?
7075-T6, 2024-T81 aluminum alloys, and magnesium alloys should not be hot-dimpled
What should be done to protect a riveted joint between aluminum alloy and magnesium alloy from corrosion?
Coat the faying surface with a corrosion-inhibiting primer, dip the rivets in the primer and drive them while the primer is wet
Which stringer attached to a wing skin would require the greatest number of rivets for a splice?
A stringer in the lower surface
What type of rivet may be used to replace a round head rivet in an aircraft structure?
A universal head rivet
How long should a rivet be to join two pieces of sheet metal?
The combined thickness of the metal sheets plus 1-1/2 times the rivet shank dismeter
Should a riveted joint fail in shear or in bearing?
It should fail in shear. The rivets should shear before the sheet tears at the rivet holes
What is the purpose of the beehive spring on a rivet gun?
It holds the rivet set in the gun and allows the gun to vibrate the set
