Effect of Bulk Density of Developed Agglomerated Fluxes on Flux Consumption and Penetration during Submerged Arc Welding
Abstract: This paper presents the results of an experimental study correlating the bulk density of agglomerated fluxes during submerged arc welding on weld penetration and flux consumption. The basic constituents of these fluxes are CaO, SiO2, and Al2O3. Minor additions of MgO, MnO, CaF2, NiO and Fe-Cr are mixed in the basic constituents for improving techno-mechanical and physical properties of the weld metal.Keywords: Submerged arc welding, agglomerated flux, flux consumption, weld …

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 …

Selection and Mechanism of using active gas in GTAW Process – A review
Abstract: Gas tungsten arc welding process is known for its good quality welds. However, the lack of penetration of the process leads to low productivity. Many techniques have been implemented in the past to improve the joint penetration and thereby the productivity of GTAW process. In one of the technique, active gas like Carbon dioxide, Nitrogen or Oxygen is used in some proportion along with the inert gas. This addition of …

Influence of Process Parameters of TIG Welding Process on Mechanical Properties of SS304L Welded Joint: A Review
Abstract: The purpose of this study is to study the effects of various process parameters (welding current, filler materials and groove design) of tungsten inert gas welding (TIG) on aspect ratio, hardness and impact strength of SS304L welded joint. Aspect ratios are obtained by taking the ratio of bead width and bead penetration. This bead dimensions can be measured by digital vernier calipers. Weld joint quality depends on the bead dimensions. …

Effect of Electrode Extension and Width of the Plate on Distortion and Residual Stresses Using Submerged Arc Welding Process
Abstract: Welding is a reliable and efficient joining process in which the coalescence of metals is achieved by fusion and is used extensively in the fabrications of many structures, buildings, ships, pressure vessels, etc., due to many advantages it has, over the other fabrication processes. Localized heating during welding, followed by rapid cooling, can generate residual stresses and distortion. However, distortion is a problem encountered during welding. The presence of distortion …
