Study of Shielded Gases for MIG Welding
Abstract: Protecting shielding gases are inert or semi-inert gasses that are regularly utilized in few welding forms, mostly in gas metal arc welding and gas tungsten arc welding (GMAW and GTAW, more prevalently known as MIG and TIG, respectively). Their purpose is to shield the weld region from oxygen, and water vapour. Contingent upon the materials being welded, these air gases can diminish the quality of the weld or make the …

Green Manufacturing with Steel Swarf
Abstract: The industrial sector drives nearly one-third of global energy demand, with most of this energy used to produce bulk materials. However, the rate of recycling of metallic materials is much higher than non metallic ones, especially when the scrap is heavy. But in very loose swarfs the transformation rates are poor, and processes are unsustainable. To improve the life productivity of bulk materials, and also lower the specific energy consumption, …

A Novel Technique for Improved Recovery of Mg-Analysis of the Microstructure and Physical Properties
Abstract: Aluminium-Magnesium alloys are used widely in industrial applications as well as for the preparation of metal matrix composite because of their low density and high specific strength. Magnesium has a low boiling point and the recovery of magnesium is poor when it is added in pure form particularly as cheaply available turnings to the liquid metal. Magnesium is added to aluminium for increasing its wettability and thus helping in uniformly …

Review of Nitrite Inhibitor for Protection of Rebar Corrosion
Abstract: Load bearing concrete structures need steel reinforcement (rebar) strips or rods, which are prone to attack by the corrosive environment inside the concrete due to constant ingress of moisture, pollutant gases and anions (mainly Cl-, SO4- -). One of the means of reducing such type of corrosion is the use of inhibitors. Inhibitors are water soluble but film forming on metals by their selective adsorption on the metal surface. These …
