In this study, continuous drive friction welding process is selected for joint dissimilar high chromium white cast iron and mild carbon steeel. The microstructure, presence diffusion of elements, deformation in interface weld metal were analyzed by scanning electron microscopy (SEM), optical (OM), energy dispersive spectroscopy (EDS), elemental mapping X-Ray diffraction (XRD). Elemental analysi...

In this research the interface structure of dissimilar joint between AISI 4130 and AISI316L steels produced by GTAW process was evaluated. ERNiCr-3 was used as a filler metal for this joint. After welding the microstructure of different areas including weld metals, heat affected zones and interfaces were studied by optical microscope (OM), scanning electron microscope (SEM) and energy dispersiv...

Abstract This paper deals with the singular stress field at the adhesive dissimilar joint, and discusses the effect of material combination and adhesive thickness on the intensity of the singular stress when bonded strip is subjected to tension. A useful method to calculate the intensity of singular stress at the adhesive dissimilar joint is presented with focusing on the stresses at the edge c...

In this study, a penetration-controlled friction stir welding (FSW) technique was employed to lap weld dissimilar Al/Mg alloys, incorporating Zn interlayer. The joint’s microstructure, interfacial reaction, and phase composition were analyzed through optical microscopy, scanning electron X-ray diffraction. findings demonstrate the formation of hybrid joint comprising FSWed region diffusion bond...
