A New Course on ‘Welding Engineering and Design of Welded Structures’ to Better Train Engineering Graduates for The Future Sanjeev K. Khanna Department of Mechanical and Aerospace Engineering University of Missouri - Columbia Columbia, MO 65211, USA

INTRODUCTION

Welding is one of the more common methods of joining to create useful structures. It is commonly used in ground, marine and air transportation equipment, bridges, pressure vessels, machines, etc. Welding is a complex process and one of the most essential processes for the economy of any nation. It is one of those processes which enables industries to be set up, agriculture to thrive, power generation, and reliable communications, among a host of applications.

An optimum and reliable design of a welded structure requires an integrated approach to understand welding processes, materials science, fatigue design, joint failure, experimental mechanics, and inspection. Hence, the total design of a structure involving welding as one of the joining methods needs an integrated and interdisciplinary approach. Figure 1 shows the large number of variables involved in the design of a safe welded structure.

Today, examples abound which show the need for engineers and scientists who have an integrated, interdisciplinary background bridging mechanics, materials science, manufacturing, and design. Consider, for example, the High Speed Civil Transport (HSCT) vehicle, the international space station, or the future automobiles. All of these applications involve joining (welding) of a host of dissimilar or similar materials.

It may be noted that though knowledge of welding engineering and design of welded structures is central to the optimum and reliable fabrication of a large number of critical structures, to the best of my knowledge, almost all the mechanical engineering curriculums in the country do not even remotely address this issue. The proposed course will bridge different aspects of mechanics, materials science, metallurgy, manufacturing, and design. It will train the students to think critically in designing welded structures and in other design situations, and will enhance their overall design experience.

This paper presents the philosophy and the course contents of the newly proposed course. Also links between mechanics, materials science, manufacturing, and design, using modern multimedia and instructional technology, in the context of teaching prospective engineers how to approach the total design of a welded structure are presented.
