SEDALIA, Mo. (June 29, 2015) – ProEnergy’s Director of Technology, Warren Miglietti, recently attended the Turbine Forum in Nice, France, and served as Chair for the first day’s events. He was also a guest speaker, and presented on diffusion braze repairs for industrial gas turbine blades. Warren also had the opportunity to present the same presentation at the ASME Turbo Expo in Montreal, Canada.

The presentation highlighted how much progress brazing technology has made in the past decade. It described ProEnergy’s willingness to braze rotating components, depending on where the cracking distress is. Included was a case study on repairs made to W251B, row 1 blades that detailed the microstructure of the braze repair and mechanical test results, showing that the repair had mechanical integrity and strength.

 “ProEnergy thoroughly understands the benefits of both welding and brazing and utilizes both technologies to provide cost-effective and reliable repairs to our clients,” said Warren. “Combining the use of both technologies allows ProEnergy to deliver the repaired components faster.”

Warren has over 28 years of experience and expertise in the welding, brazing and heat treatment of nickel and cobalt based superalloys as well as titanium, aluminum and stainless steels. He has authored or co-authored 47 published technical papers and has six repair technology patents granted, with three repair technology patents pending. Highly regarded in the industry, Warren received an award for Special Contribution to the field of Brazing from the Chinese Welding Society (CWS). Warren received his M.S. in Metallurgical Engineering and Welding Engineering from the University of Natal in South Africa and his Ph.D. in Metallurgical Engineering at the University of Pretoria in South Africa.
