Abstract Failure caused by stress corrosion cracking (SCC) is inevitable during the long-term service of nuclear power pipe welds. This mainly due to propagation microcracks in deposited metal, which seriously affects operation safety pressure pipes. Overlay welding practical for repair welding, can introduce compressive residual inside weld seam. In this work, a diagonal T-pipe joint was fabri...

Synthesis gas manufacturing by steam reforming of hydrocarbons is an important industrial process. High endothermic nature of the process makes it one of the most cost and heat intensive processes. In the present work, composite effect of different inert gases on synthesis gas yield, feed gas conversion and temperature distribution along the reactor length has been studied using a heterogeneous...

An adaptive control based on fuzzy logic has been implemented for Gas Tungsten Arc Welding (GTAW). This adaptive controller eliminates the problems frequently experienced with traditional Automatic Voltage Control (AVC) systems, which do not adequately perform for all operational conditions because of the non-linear relationship between the arc voltage, current and arc length. This paper examin...
