A large percentage of riveting of airplane structure is accomplished on thin gauge aluminum alloy,

blows or riveting tools. All airplane power riveting is accomplished by upsetting the rivets against
a bucking bar instead of striking the shank with a hammer. To prevent deforming the rivet head,
a rivet set must be selected to
fi
t each type of rivet. The depth of this set must not touch material
being riveted. Parts requiring heat treatment should be heat treated before riveting, since heat
