Description

The Iowa Demonstration Laboratory (IDL) is an outreach arm of the Center for NDE that works primarily with in-state clients. Over a course of time, various clients have approached the IDL with a similar query: how do we nondestructively test spot welds? In our work with these clients, we encountered anecdotal information about the success or failure of various means of evaluating spot welds, and sometimes conflicting interpretations of the ease of use of competing techniques. Additionally, published articles seldom contrast the efficacy of different test methods used on the same samples. It appears that a consensus to interpreting weld conditions does not exist, presumably due to a range in effectiveness of various techniques over a range of possible welded materials. This project, in effect, will attempt to determine the best inspection method over a wide variety of welded materials, and, ideally, generate guidelines on how best to implement the various techniques.

Evaluation of Spot Welds by Various Techniques
