Diagnostis of longitudinal welded joints of tubes by the method of magnetoelastic acoustic emission
Journal Title: Вісник Тернопільського національного технічного університету - Year 2017, Vol 88, Issue 4
Abstract
The microstructure of the steel 19H and 17H1S pipes after long-term operation is investigated. Dependence of the magnetoelastic acoustic emission signals characteristic change on the structure of different areas of the welded joint is determined. The effect of residual stresses after welding on the change of the signals amplitude sum of magnetoelastic acoustic emission has been investigated.
