The throttling flowmeter used in utility boilers has been as a measuring instrument for long time. However, its safety performance, such welding, lacks enough attention. manufacturing welds of the are welded with austenitic stainless steel and pearlitic heat-resistant steel. Cracks other defects generally found inspection detection flowmeters service, which have serious potential accidents. To ...

This paper discusses a number of special ultrasonic NDE problems of particular interest to inertia and friction welds, but most of the results can be readily applied to other similar or dissimilar solid-state bonds as well. One of the major problems associated with dissimilar bonds is the "blinding" effect of the strong interface reflection caused by the inherent elastic discontinuity at the ot...

Abstract The Mechanical and Stretch-Bend Failure studies on Ultra High Frequency Pulsed Gas Tungsten Arc Welded dissimilar joints of AISI409-AISI430 Ferritic Stainless Steels were conducted. Welding was conducted with 5 ultra high frequencies (50 Hz, 150 250 350 450 Hz). characteristics evaluation the included tensile strength, microhardness variations across welds creep. Microstructural metall...

in this study, an attempt was made to minimize the corrosion rate and maximize pitting potential of dissimilar metal welded joints of a387-gr91/aisi316 steels. process parameters of the pulsed current gas tungsten arc welding (pcgtaw) including of peak current (p), background current (b), pulse frequency (f), and on time percentage (o) were chosen as the influencing factors on corrosion behavio...

Thin sheets of Al/Cu dissimilar materials are overlap welded for the electrical connection secondary battery electrodes by laser welding. The weld penetration depth is an important joint quality to ensure strength and conductance. It difficult predict using analytical methods because high reflection small thickness base materials. Several machine learning algorithms were investigated develop re...
