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...

Abstract This article introduces The Immersive Guitar (TIG) Project, a proposed sonic performance installation that doubles as an intimate acoustic venue. TIG Project responds to several needs, highlighting relations between place and performance, music architecture. needs concern rarity of suitable, spaces for appeal more creative solutions in the provision such spaces, which would afford nove...

This document shows how the factorized syntactic descriptions provided by MetaGrammars coupled with factorization operators may be used to derive compact large coverage tree adjoining grammars.

Next-generation composite Al-Mg-Zr fuels for bio/chem-agent defeat applications rely on intermetallic formation reactions to reduce ignition temperatures below melting point of Al. Scaling-up the ball-milling synthesis these powders will require a detailed understanding how milling parameters and powder composition impact evolution microstructure. In present work, we explore effect duration siz...

Corresponding author, Email: [email protected] This work compares the weldability of ductile iron when: (I) a root weld is applied with a tungsten inert gas (TIG) process using an Inconel 625 source rod and filler welds are subsequently applie...

Welding of niobium and tantalum materials is currently conducted in vacuum or inert gas chambers, which limits the size of the equipment to be produced. The objective of this study is to investigate the means to make TIG welding on these materials in atmospheric environment and analyse the effect of heat input on the properties of welds. It was found that it is possible to make TIG welds on the...
