Embodiment Construction

[0055] The following detailed description is merely exemplary in nature and not intended to limit its application and uses. Furthermore, there is no intention to be bound by any expressed or implied theory presented in the preceding technical field, background, brief summary or the following detailed description.

[0056] figure 1 is a simplified cross-sectional view of an improperly installed self-piercing rivet 20 and the abnormal joint 22 formed thereby in a workpiece 24 . The workpiece 24 is a metallic structure having a first side 26 and a second side 28 . Workpiece 24 may be combined with other workpieces (not shown) to construct any desired structure. Examples of such structures include, but are not limited to, aircraft fuselages, ship hulls, and structural components on motor vehicles.

[0057] The workpiece 20 includes a first metal member 30 and a second metal member 32 . The first metal member 30 and the second metal member 32 are substantially planar members ha...

Abstract

A method is disclosed for repairing a workpiece having two metal components riveted together. The workpiece has a discrepant joint caused by an improperly-installed-self-piercing rivet. The method includes, but is not limited to providing a repair rivet, positioning the repair rivet proximate the discrepant joint such that the repair rivet is substantially aligned with the improperly-installed-self-piercing rivet, and installing the repair rivet at substantially a same location on the workpiece as the improperly-installed-self-piercing rivet without removing the improperly-installed-self-piercing rivet.

Description

technical field [0001] The technical field relates generally to self-piercing riveted workpieces, and more particularly to methods of repairing self-piercing riveted workpieces. Background technique [0002] Many articles of manufacture require that metal components be attached to each other to form various structures. Aircraft fuselages and automotive vehicle bodies are examples of such structures manufactured by joining one or more metal members. There are many different methods of joining metal pieces together, one of which involves the use of metal rivets, which create a mechanical connection between two metal pieces. [0003] There are many different types of rivets that can be used to join metal components together. One type of rivet is the self-piercing rivet. Self-piercing rivets generally have a head and a shaft which is hollow along at least the end portion opposite the head. In some embodiments, the end portions are sharpened to allow the self-piercing rivet t...
