A nickel-based filler wire, Inconel 82, was applied to weld a high-silicon steel plate with chemical composition in wt% of 2.6 Si, 0.5 Al and Fe balance. The the heterogeneous bead deviated from that conventional alloy due incomplete mixing/convection between wire base metal pool. microstructure examined greater depth by FESEM/EBSD, EPMA/WDS STEM/EDS experiment. primarily composed austenite mar...

As it is known, starting with the 19th century, constructions metallic strength structure have acquired a wide development. From simple supports for various structures to most complex constructions, we find elements that must be joined together in ways. One of simplest methods, constructive and economic, joining components welding. The study presented this paper deals numerical determination st...

In welded tubular joints, when the fatigue crack depth is less than 20% of chord wall thickness, the crack growing process is highly affected by weld geometry.&#10 Hence, T-butt solution and weld magnification factor (Mk) are applicable tools for evaluating the crack growth rate in this domain. In this research, the capability of Artificial Neural Network (ANN) for estimating the Mk of weld toe...

This paper analyzes the corrosion resistance and mechanical microstructural properties of a welded joint ductile cast iron using AISI316L stainless steel as filler material three different heat treatments: preheating at 250 450 ºC post-weld annealing treatment. The results show presence ledeburite interface between weld bead affected zone root pass, along with loss strength ductility when weldi...

In this study, AA 6063 aluminum was joined using Tungsten Inert Gas (TIG) welding with a butt joint. The ER-5356 filler metal feeding method is used intermittently to find its effect on weld geometry, mechanical properties, microstructure, and chemical composition. dimensions of the specimens in study were 120 mm × 50 mm, thickness 3 mm. ratio configuration feed time delay time. length wire var...

The aim of the present work was to study the effect of various process parameters i.e. current, voltage, travel speed, electrode diameter, flux composition, pre heating of workpiece, electrode stick-out and edge including angle on changes in tensile strength and toughness of the weld bead geometry of HSLA Steel and to optimize the process so that minimal changes occur in the material properties...

The use of shielding gases in laser beam welding is particular interest for materials interacting with ambient oxygen, e.g., copper, titanium or high-alloy steels. These are often processed by remote where short welds (e.g., up to 40 mm seam length) commonly used. Such setups prevent gas nozzles from being carried along on the optics due scanner application and a small area needs be served loca...
