Guaranteeing the safety of short welds in automotive applications. Most safety-critical welds in the automotive and related industries are of short duration (less than three seconds). We will develop a unified theoretical model of short welds which accounts for all important phenomena. Using this model, we will create the first system to check every safety-critical weld in real time, with 3D data objects that use all the data available from the non-stationary process.

Mechanics of mixed film lubrication in strip rolling. Rolling speeds of tandem cold rolling mills for thin steel strip are often limited by hot scratches and self excited chatter vibration, which forces the mill to slow down. Consequently the output is reduced and significant out-of-specification materials produced. Operating practices are guided by experience and trial-and-error method. In this project, a comprehensive model will be produced to quantify the effects of relevant parameters that c ....Mechanics of mixed film lubrication in strip rolling. Rolling speeds of tandem cold rolling mills for thin steel strip are often limited by hot scratches and self excited chatter vibration, which forces the mill to slow down. Consequently the output is reduced and significant out-of-specification materials produced. Operating practices are guided by experience and trial-and-error method. In this project, a comprehensive model will be produced to quantify the effects of relevant parameters that can provide a much better understanding of the rolling process at speeds higher than previously possible, and help to improve its productivity as well as product quality.Read moreRead less
