Kielhorn Welding Engineering Lab

 

Materials Joining Engineering Lab Space

Most of the Materials Joining Engineering facilities are housed in the 8600-square-foot Kielhorn Welding Engineering Laboratory, the largest stand-alone Materials Joining Lab in the nation. The lab contains over a million dollars worth of equipment, virtually all of which is available to students for class projects and research experiments.

The lab contains equipment to facilitate any number of different welding and joining processes, including multiple types of arc welding, spot welding, friction stir welding, brazing, soldering, adhesive bonding, hybrid joining and more.

The lab also contains equipment that enables automation and control, weldability testing, characterization, mechanical testing, nondestructive evaluation and design and analytical computing.

Why is it called the Kielhorn Welding Engineering Laboratory?

For 45 years, William "Bill" Kielhorn diligently educated welding engineers and welding engineering technologists at LeTourneau University. Despite being hospitalized for stage IV colon cancer during his last semester, Kielhorn never missed a class in his entire 45-year career. His last lecture was given via Skype from his hospital bed.

Just days later, LeTourneau University commemorated his life and career by naming the university’s welding lab the Kielhorn Welding Engineering Lab in his honor. Kielhorn was released from the hospital for a few hours, allowing him to attend the dedication ceremony. Eight months later, Mr. Kielhorn’s battle with cancer took him to be with the Lord.
