Materials Joining Engineering Labs

 

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.

 

 

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.

LETU students use the biomedical engineering facilities to complete projects for individual courses, as well as for research conducted for senior design projects.

  • Motion Analysis System
    The Motion Analysis system allows students to conduct motion capture, building a three-dimensional model of test subjects in movement for analysis. The motion analysis equipment, valued at more than $200,000, was purchased through an NSF grant written by LETU faculty members. LeTourneau is one of the few undergraduate programs in the nation to have such a system.
  • BioSignal Studies
    In addition to the motion analysis equipment mentioned above, the NSF grant was also used to purchase equipment for studies in bioinstrumentation to obtain computerized measurements of cardiovascular, respiratory, and neurological functions. Signals such as the EEG, EKG (ECG) and EMG are then processed to maximize information content.
  • Electromyography (EMG) System
    The BME laboratory is equipped with a wireless EMG system measuring the electrical signals outputted by multiple muscles when activated.
  • Six Degree of Freedom Force Plate
    The pit in the BME laboratory contains 20 individual tiles that are removable. Two six-axis force plates are installed into the pits to accurately measure multi-dimensional ground reaction forces. These forces result from such actions as a person walking over the force plate or jumping on it. The data from the force plates are combined with the kinematic data from the motion capture system and the EMG system to provide comprehensive analyses of human movement.
