austenitic stainless steel sheets have gained wide acceptance in the fabrication of components, which require high temperature resistance and corrosion resistance such as metal bellows used in expansion joints in aircraft, aerospace and petroleum industries. in the case of single pass welding of thinner sections of this alloy, pulsed current micro plasma arc welding (pcmpaw) has been found bene...

Abstract The problem of corrosion in the industrial oil and gas pipes has been one major contributors catastrophic structural failures. Among various types corrosion, under insulation (CUI) known to cause serious problems. Pulsed eddy current (PEC) non-destructive testing shown its effectiveness detecting hidden CUI. Most PEC systems have developed by using an inductive coil as their sensing de...

Locating and characterizing rolling contact fatigue (RCF) cracks in rails is gaining attention the railway industry. Eddy current pulsed thermography (ECPT) can detect such by combining benefits of electromagnetic excitation thermal diffusion. To date, most studies focus on investigating specific features based artificial defects, verification real lacking. In this article, to establish best me...
