Plates of 3–5 mm in thickness were extracted from an AZ91D ingot and then butt joints of the plates were produced using tungsten inert gas (TIG) welding method. The TIG arc was also used to deposit welding beads on some of the thin plates. No cracking was found in the butt joints. However, hot cracking was always observed to propagate from the heat affected zone (HAZ) under the welding bead int...

Abstract Hastelloy C-276 is a nickel-based alloy with high strength and corrosion resistance at cryogenic to temperatures. The issue of shallow penetration by Tungsten Inert Gas (TIG) welding was addressed in the current investigation applying A-TIG variable oxide flux. In investigation, constant conditions were used perform TIG using SiO 2 , TiO 50% mixture + weld bead width depth profile meas...

Plate bending fatigue tests were conducted for the Mg-9mass%Al-1mass%Zn-2mass%Ca alloy joints prepared by friction stir welding under two different conditions of stress ratio 0 and -1. The limit FSW was above 80% that base metal all test conditions. Fracture origin observed at thermo-mechanically affected zone (TMAZ) in joints. higher than inert gas (MIG) tungsten (TIG) fused (FZ) both MIG join...

The dyeing of textile materials is the most critical process in cloth production because of the strict technological requirements. In addition to the technical aspect, there have been increasing concerns over how to minimize the negative environmental impact of the dyeing industry. The emissions of pollutants are mainly caused by frequent cleaning operations which are necessary for initializing...

Arc welding processes, such as shielded metal arc (SMAW), inert gas (MIG), and tungsten (TIG), play an important role in industrial applications. To improve the efficiency of exploitation traditional systems, new technologies have been used. Virtual reality technology is one them. The virtual (VR)-based system enables to increase frequency practice help learners obtain experience avoid errors t...

Abstract Ferrous alloys are employed in a range of fields, including aerospace, construction, automobiles and chemical processing. One the most used welding processes for fusion ferrous metals is gas tungsten arc (GTA) or Tungsten Inert Gas (TIG) welding. Due to lower amount penetration accomplished using only one pass, less frequent some industrial situations. Fluxes have been discovered impro...

Nosocomial infection by multi-drug resistant bacteria (MDR) e.g: extended-spectrumBeta-lactamase(ESBL) producing Enterobacteriaceae, Acinetobacter baumannii and carbapenem-resistant Enterobacteriaceae (CRE) is increased worldwide, with major burden due to limited choices of antibiotics (Peleg & Hooper, 2010, Magiorakos et al.,2012). Tigecycline (TIG) and Colistin (COL) are examples of the few d...

Carbon monoxide (CO) oxidation is considered an important reaction in heterogeneous industrial catalysis and has been extensively studied. Pd supported on SiO2 aerogel catalysts exhibit good catalytic activity toward this owing to their CO bond activation capability thermal stability. Pd/SiO2 were investigated using carbon as a model reaction. The catalyst becomes active, the conversion increas...

Welding is the process of coalescence two metals/alloys for creating a seamless joint, quintessential fabrication utilised in almost every manufacturing sector. There range welding processes that are used according to their features and requirement fabricator. The tungsten inert gas (TIG) an extensively owing its inherent characteristics like high weld quality, surface cleanliness, autogenous m...
