Ronalb,
For several years, vibratory stress relief has originated a lot of discussion on its effectiveness: is it really good or not? Many say yes, many say no. As a matter of fact, the applicable American codes (ASME, ANSI etc.) are silent about it: neither approve nor forbid its use. Am I wrong? If so, someone correct me, please.
I believe you could render a good service to us, frequentors of the AWS site: after you have used the vibratory stress relief, tell us what your actual experience has been, whether good or bad.

Dear Ron,
My former professor Mr. Jarmai could help you. Contact him.

Dr. JÁRMAI, Károly is a professor in the Faculty of Mechanical Engineering at the University of Miskolc, Hungary. He graduated as a certified mechanical engineer and received his doctorate (Dr.univ.) in 1979 at the University of Miskolc. He teaches design of steel structures, welded structures, composite structures and optimization in Hungarian and in English language for foreign students. His research interest includes structural optimization, design of welded structures, cost
calculation, mathematical programming techniques and expert systems. He made his C.Sc. (Ph.D.) dissertation at the Hungarian Academy of Science in 1988. He became European Engineer (Eur. Ing. FEANI, Paris) in 1990. He has got the habilitation (Dr.Habil.) at the University of Miskolc, in 1995. He has defended his D.Sc. thesis at the Hungarian Academy of Science with the economic design of different steel structures, optimization and expert systems in 1995. He has published
over 160 technical papers, student aids, textbook chapters and conference papers.
