Welding Engineering

While many people think of welding in terms of a process, it is in practice a complex engineering discipline that involves aspects of materials science & metallurgy, lasers, thermodynamics, design, inspection & quality assurance, robotics, and mechanical, electrical & electronic systems.

Welding engineers must understand the properties behind the joining of materials to ensure that joined structures are safe and a benefit to society. Welding engineers have expertise in materials science, including steels, nonferrous alloys and polymeric materials, and in process technology, including arc welding, lasers, resistance welding, brazing and soldering. They also are experts in robotics, from programming and applications to sensors and controls.

The Center for Weldability Evaluation

The Center for Weldability Evaluation (CWE) is located within the EJTC facility on west campus and is dedicated to:

  • addressing failures and loss of properties in welds of advanced alloys
  • implementing advanced alloys in critical weld structures
  • supporting invention and development of metallic alloys with improved weldability
  • developing innovative tools and methods for weldability evaluation
  • contributing to the improvement of energy efficiency, safety, service performance and reliability in power generation and power conversion systems

Their testing capabilities include cast pin tear test, DIC tensile testing, delayed hydrogen cracking testing, and stress relief cracking test. Graduate, undergraduate and post-doctoral students perform the technical research and testing under the direction of Professor Boian Alexandrov.
