Experience

Jonathan Hovde joined WJE in 2019 as a metallurgical engineer with more than thirteen years of experience. He has experience in several different industries, with a primary focus on failure analysis. As a metallurgist for a top American steel mill, Mr. Hovde consulted on various steel fabrication and forming projects related to building products, automotive components, and various other manufactured goods. While serving as a contractor for the U.S. Army, he developed detailed knowledge and experience related to mechanical systems within military rotorcraft and their unique metallurgical and materials requirements. As a materials engineer for an independent consulting laboratory, Mr. Hovde has performed failure analysis and consulted on design and process revisions of gas turbine engine components, biomedical implants, and industrial equipment components constructed of various alloys including nickel based super alloys, titanium, and steels. He has examined components fabricated using metal additive manufacturing (MAM) processes and is familiar with the unique challenges that these new materials and processes present.
