Meet the EWI Arc Welding Team – Ian Harris

July 23, 2012

This week’s “Meet the Team” features Ian Harris.  Ian has been at EWI for many years and has plenty of experience with arc based welding processes. Please don’t hesitate to contact Ian if you have any questions or interests related to EWI or Arc Welding. You can reach him at 614.688.5000 or iharris@ewi.org.


Technical Expertise

Following graduation from the University of Surrey, and internships at SNECMA, France and Telcon Metals, UK, Ian Harris joined Tube Investments in their bellows and expansion joint manufacturing division.  In 1984, he joined the Arc Welding Department at The Welding Institute where he worked for 6 years as a research engineer and then a senior research engineer.  Ian became an EWI employee in 1990.  His main research interests include gas-shielded arc welding processes.  He is primarily concerned with application studies for these processes, involving procedure development for the welding or cutting of a range of materials.  As a Principal Engineer Ian was responsible for initiating, conducting, and reporting research and contract work.  He has over 28 years experience with applied research, consulting, and in-plant troubleshooting in arc welding.  This experience is also used in fusion processes (arc, laser, and EB) for additive manufacturing.

Background and Project Experience

Ian has conducted many projects in gas-shielded arc welding processes, including gas metal arc (particularly pulsed) welding (GMAW), gas tungsten arc welding (GTAW), and plasma arc welding (PAW) processes.  He has authored over 150 reports and papers on arc welding, including many technical reports for sponsored work such as welding procedure development and evaluation of shielding gases.

At EWI, he has led projects for sponsors in many industries including automotive, aerospace, oil and gas, and heavy manufacturing, and in the several years has focused predominantly on aerospace markets for arc, laser and EBW applications.  Oil and gas projects have focused on pipeline welding and tube and pipe applications for orbital GTAW of duplex and superduplex stainless steels.  In the power generation market, work undertaken included turbine rotor repair by the GTAW and pulsed-GMAW processes, and procedure development for pulsed-GMAW of beryllium copper alloys intended for the toroidal field coils of an advanced fusion power reactor.  Work in recent years has included projects on welding of aluminum alloys for shipbuilding and ASME IX aluminum piping systems qualification for UF6 nuclear fuel enrichment, and GTAW for aerospace applications involving stainless steels, nickel alloys, and titanium alloys.

Based on a strong background in metallurgy and welding engineering, Ian also serves as Director, Additive Manufacturing Consortium (AMC), a consortium of 26 aerospace- and defense-focused industry primes, SMEs, government agencies, and academic institutions focused on increasing the manufacturing readiness of metals additive manufacturing (AM).  In 2011 EWI Chaired the first Metals Additive manufacturing Symposium at MS&T with 50 papers on metals AM.

Additional areas of expertise are thermal spray coating, plasma cutting and water jet cutting.
