Review of Progress in Quantitative Nondestructive Evaluation
Center for Nondestructive Evaluation

Begun in 1973, the Review of Progress in Quantitative Nondestructive Evaluation (QNDE) is the premier international NDE meeting designed to provide an interface between research and early engineering through the presentation of current ideas and results focused on facilitating a rapid transfer to engineering development.

This site provides free, public access to papers presented at the annual QNDE conference between 1983 and 1999, and abstracts for papers presented at the conference since 2001.

Abstract

The automotive industry is increasingly interested in using adhesive bonding in the construction of body shell assemblies. Adhesive joints offer some significant potential advantages over conventional welding techniques, including improved strength and stiffness, greater flexibility in designs, and reduced costs. The NDE requirements associated with the introduction of adhesive bonding include the confirmation during construction that the dimensions of the adhesive in the joint are within specified tolerances. In the common case of a lap joint, illustrated in Figure 1, the key dimensions are the bond thickness and the overlap length.
