LETU materials joining engineering students Peter Morris, left,  and Timothy Pickle  won first place for their poster at the 2017 FABTECH conference in Chicago.

LeTourneau University materials joining engineering students earned first place in the Baccalaureate Engineering/Engineering Technology poster competition at the 2017 FABTECH Expo recently in Chicago. Three peer-reviewed scientific talks also were presented, based on research conducted at LeTourneau University.

FABTECH is North America's largest collaboration of technology, equipment and knowledge in the metal forming, fabricating, welding and finishing industries.

LETU undergraduates Timothy Pickle, Peter Morriss and Christian VonQualen won first-place overall and a $750 cash prize for their poster, Super Duplex Stainless Steel: Effects of Multi-Pass Welding Parameters on Microstructural Stability.

Judged the best among competitors from Ohio State University, Lehigh University and the University of Alberta, the LETU students' poster described their 2017 summer research work completed at LeTourneau University's main campus in Longview through a grant from the Bechtel Global Corporation and in-kind support from Outokumpu and ARC Specialties.

Advising the students during their research were LETU professor emeritus Yoni Adonyi, assistant professor Wes Downing and materials joining engineering program director Richard Baumer. Their research continues during the 2017-2018 academic year as a senior design project under Baumer's direction.

LETU's 13-member materials joining engineering delegation to FABTECH also made successful presentations of three peer-reviewed scientific talks, including:

Intermetallics in Steel-to-Aluminum Friction Stir Welds by Kayode Oyedemi, Yoni Adonyi and Puhao Wang

Nitrogen Shielding Effects in Duplex Stainless Steel Welding by Balazs Varbai, Yoni Adonyi, János Dobránszky, Tim Pickle, Richard Baumer and K. Májlinger

Intermetallic Characterization in Metal-to-Ceramic Microwave Joining by Ian Reiman, Kayode Oyedemi and Yoni Adonyi.

More than 50 LETU alumni, students, faculty and staff also gathered for the annual materials joining engineering alumni dinner.

Steve Starrett, dean of the School of Engineering and Engineering Technology, announced the university has approved hiring a new professor to fill the Kielhorn Professorship to serve as the third full-time professor in LETU's materials joining engineering program. The professorship is an endowed chair in welding and materials joining engineering made possible through the generous support of alumni giving, American Welding Society matching funds and industry support.

During the dinner, LETU alumni also celebrated the 21 years of the materials joining engineering program leadership by Yoni Adonyi, now a professor emeritus, and shared highlights from his career. Adonyi, a 2015 American Welding Society fellow, was honored with his emeritus professor resolution and was presented with a plaque commemorating his service.
