In today's dynamic changing environment, for industries to remain internationally competitive, traditional manufacturing techniques used for welding have to become more flexible and intelligent to attain better adaptability and higher productivity. In industrial applications of MIG/MAG welding processes, various types of shielding gases are used based on type of work material and weld quality required. In this proposed research, experimental studies will be conducted on welding productivity by using different shielding gas combinations. The aim of this project is to conduct experimental analysis on weld arc phenomenon, weld pool behavior, and weld quality and to build an intelligent system for the selection of optimum combination shielding gas mixtures. In addition this study also aims to examine how the microstructure and mechanical properties of different welds are influenced by the use of different shielding gases combinations.Read moreRead less

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. The outcomes will be a comp ....Guaranteeing the safety of short welds in automotive applications.

Diode lasers offer significant advantages for laser thermal processing over conventional CO2 and Nd:YAG lasers in terms of their output wavelength, size and efficiency. The mobile high power diode laser facility will help build a strong infrastructure for in-situ repair of worn components and is expected to reduce overall component repair costs and time.Read moreRead less
Developing a scientific relationship between non-destructive testing ("NDT"), manufacturing acceptance levels and integrity requirements for pressure equipment welds. The acceptance of pressure equipment welds involves the interplay of three engineering fields: manufacturing acceptance standards, non-destructive testing and structural integrity analysis.

In recent years these developments have acceler ....Developing a scientific relationship between non-destructive testing ("NDT"), manufacturing acceptance levels and integrity requirements for pressure equipment welds. The acceptance of pressure equipment welds involves the interplay of three engineering fields: manufacturing acceptance standards, non-destructive testing and structural integrity analysis. Historically each of these fields has been developed separately by different research groups. In recent years these developments have accelerated with new demands on failure risk, a revolution in NDT techniques and advances in structural integrity analysis. As a result there are now large inconsistencies between the various requirements which lead to serious disputes in industry.
This project seeks to redefine the appropriate relationship between the fields and develop a scientific and logical pathway for standards development.Read moreRead less
