Materials Joining Engineering is a hybrid discipline that combines the fundamental principles of materials, mechanical, structural and electrical engineering, adapting them to the development and application of joining technology.
This includes materials selection, characterization and weldability assessment, procedure development and qualification, process automation and control, as well as the design, inspection, analysis and testing of joined structures and components.
LeTourneau University is one of only three universities in the nation that provides an ABET-accredited engineering program with a welding or materials joining concentration.
Graduates of LETU's BSE program with concentration in materials joining engineering are highly sought after and receive some of the highest paid engineering jobs available.
Materials joining is a general term encompassing many different processes, including various methods of welding, brazing, soldering, adhesive bonding and even some kinds of mechanical fastening. Advances in the technology of these processes enable a wide variety of materials, such as metals, ceramics, polymers, composites and electronic materials, to be joined in ways that maximize reliability and minimize cost.
Materials joining engineers invent new, safer and more efficient processes, create engineering specifications, and contribute to the performance and integrity of everything from consumer products to space vehicles.

FSW uses a rotating tool to ‘mix’ the solid metal together, creating a metallurgical bond.
The U.S. Transportation Dept. is looking for an effective way to join High Performance Steel (HPS) 70 and A1010 stainless steel with FSW, and LETU students are developing ways to improve the process.
The Additive Manufacturing Fusion Processes Senior Design Team is working to model, make, and test a Functionally Gradient transition piece for joining CrMo Steel to Nickel based alloys. The transition piece is needed due to different coefficients of thermal expansion and the thermal loading that joints can experience in certain applications. Successful completion of the project will lay the groundwork for other currently difficult joints between dissimilar metals.
Engineers who understand the engineering aspects of joining materials are sought after by companies that produce:
