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 …

A Review: Distortion Control in 20MnMoNi55 Material Using GTAW and SAW Process
Abstract: Gas tungsten arc welding (GTAW) is high quality and high precision welding process which is suitable for welding thin metals. Inert gases such as helium and argon, carbon dioxide, nitrogen etc. are used as shielding gases to prevent the weld bead from air, dust and other contaminations in welding. There are so many welding process parameters affecting the weld quality in GTAW. Important process parameters which mainly affect the weld …

Invisible Shield: How the Atmosphere Keeps Us Safe from Space
Abstract: Invisible Shield shows us how incredible Earth's atmosphere is at keeping us safe from space threats. The atmosphere is a moving, multi-layered shield that keeps us safe from harmful solar radiation and burns up meteoroids before they impact the ground. This page discusses about the science behind climate control, magnetic interactions, and atmospheric chemistry. It depicts how various systems work together to keep the ground stable. It also talks about …

MAP: The Invisible Shield Protecting Our Product's Journey
Abstract: Modified Atmosphere Packaging (MAP) has established itself as one of the most reliable and widely adopted preservation technologies in the modern food industry, offering a practical means of extending shelf life while maintaining the sensory and nutritional integrity of food products throughout storage and distribution. The fundamental working principle revolves around deliberately altering the gaseous composition within sealed packages, primarily through the strategic use of carbon dioxide, nitrogen and oxygen …

Optimization of Stellite Defect in Manufacturing of Engine Valves: A Review
Abstract: Intake and exhaust valves are the important components of an engine valves which are used to control flow and replacement of fuel gases inside the cylinder. This work mainly deals with defect known as stellite defect in different sizes of engine valves; and methodology adopted to prevent valve from stellite defect. Valve base material is low alloy steel (AISI 4140) and upper surface of engine valve is generally hard faced …
