WE4115 and WE7115 - Computational Analysis of Welding Processes and Welded Materials

Introduction of advanced materials makes the welding and joining process a high-value added step in the overall manufacturing life cycle. As a result, there is a need to reduce the

number of trial and error experimental welding/joining process developments to maximize the cost savings and accelerate the introduction of these materials. Various computational models have been developed to describe the interaction of various physical processes to describe the final microstructure and properties of welds. This approach is currently being adopted by automotive, aerospace, chemical, energy, microelectronics, and medical industries. This course will allow students develop and implement these models.

Welding Process Modeling

These lectures are designed to teach students modeling welding temperature and residual stresses using Abaqus.  A real-world dissimilar metal weld consisted of a carbon steel tube welded to a stainless steel tube using nickel filler metal is simulated.

Class Projects

The main objective of class projects is for students to enhance the use of computational analysis in solving real-world problems.  A class project consists of the following tasks:

• Identify a practical problem
• Make a case for the value of applying computational tools
• Perform a critical literature assessment to understand the state-of-the-art of such modeling
• Formulate the modeling strategies (e.g., what physics to model, and what assumptions to use)
• Perform an initial modeling
• Report results

Class project example

In AU13 semester, a variety of topics were studied by the students, ranging from cold metal transfer, welding of steel castings, to transient liquid phase bonding.  The following picture, showing the simulated deformation field during resistance welding a niobium strip to a nickel block, is taken from the class project report by Dan Sorensen. His final report can be viewed / downloaded from here.
