In this paper, maximum value of energy to break at Charpy impact test as a criterion of fracture toughness of AISI 316/A387 Gr.91 weld joints with ERNiCrMo-3 filler metal were obtained by optimization of pulesd current gas tungsten arc welding process parameters. The selected parameters were peak current, background current, frequency and on time percentage that were changed in three levels. Th...

In this study, a Cr-modified NiAl coating was fabricated by weld cladding technique using Gas- Tungsten Arc Welding (GTAW) process on 310 steel. Chemical composition and microstructure of the coating was studied by X-Ray Diffraction (XRD), optical microscopy and scanning electron microscopy equipped with an Energy Dispersive Spectroscopy (EDS). The wear behavior of the coated steel was examined...
The aim of this study is to investigate the optimization process parameters for Metal inert gas welding (MIG). In the present work, bead-on -plate welds were carried out on MS 5986 Fe 410 carbon steel sheets using Gas Metal Arc Welding (GMAW) process. In this present investigation ER70S-6 solid wire having 1.2 mm diameter was used as an electrode with direct current electrode positive polarity....
Development, optimisation and qualification of welding additive manufacturing procedures to date have largely been undertaken on an experimental trial error basis, which imposes significant costs. Numerical simulations are acknowledged as a promising alternative experiments, can improve the understanding complex process behaviour. In present work, we propose simulation-based approach study char...
In recent years, numerical heat and fluid flow models have provided significant insight into welding processes and welded materials that could not have been achieved otherwise. However, these calculations are complex and time consuming, and are unsuitable in situations where rapid calculations arc desired. A practical solution to this problem is to develop a neural network that is trained with ...
