A review on techniques for optimizing process parameters for TIG Welding Alum...ijsrd.com
Tungsten inert gas welding is one of the widely used techniques for joining ferrous and non-ferrous metals. TIG welding offers several advantages like joining of dissimilar metals, low heat affected zone, absence of slag etc. Gas tungsten arc welding, GTAW, uses a non consumable electrode to produce the weld. Weld area is protected from atmospheric contamination by a shielding gas (usually inert gas such as argon) and a filler material is normally used. The weld pool is easily controlled such that unbaked root passes can be made, the arc is stable at very low welding currents enabling thin components to be welded and the process produces very good quality weld metal, although highly skilled welders are required for the best results. The welding parameters are selected by operator based on experience or from a handbook. However, this does not ensure that the selected welding process parameters can produce the optimal or near optimal weld pool geometry for that particular welding machine and environment. The aim of this paper is to review the techniques of optimizing process parameters of TIG welding process.

Aluminium Alloy is containing high strength,
light weight and good Corrosion resistance. Then Gas
tungsten arc welding (GTAW) is an important joining
method for high strength aluminium alloys using
applications in transport applications like that marine,
aerospace, bicycle components, marine Engine components,
External throw away tanks for military aircrafts and other
industries. Gas tungsten arc welding have been used to
investigate the Weldability of high strength aluminium
alloys. Some important GTAW process parameters and their
effects on weld quality are discussed. Mechanical properties
of welds such as tensile strength and hardness properties are
discussed. The aim of the report is to investigation in GTAW
of high strength aluminium alloy 7075 and to provide a basis
for follow-on research.
At present scenario, INCONEL alloy 625 becomes widely used material in aero industry due to its High
tensile, creep, and rupture strength, outstanding fatigue and thermal-fatigue strength, oxidation resistance, and
excellent weld ability properties. In present work, the plates of 50mm×50mm×3mm are modelled and assembled
for v-butt joint using solid works. This model is imported in the FEA software (ANSYS) to carry out the transient
thermal analysis. The analysis is carried out with different combinations of welding parameters such as voltage,
current, velocity, speed and melting efficiency. From the analysis result, the temperature distribution at various
locations around the weld bead is evaluated. From structural analysis result, the distortion of work piece due to the
thermal effect is analysed.

Tungsten Inert Gas welding (TIG) is one of the most important joining technologies in welding-related fabrication. High quality weld joints without spattering and slags qualify this welding technology for the major part of metals. As the filler-metal supply is separated from the arc, the molten pool can be controlled in the best way possible an advantage which ensures the quality of the execution of the weld but entails a relatively low deposition rate and welding speed. When manufacturing consumer products where appearance is of importance; then the choice has to be TIG welding. Jobs that call for code requirements such as nuclear work, piping, and high profile consumer goods often require at least the first weld in the pipe joint to be TIG welding for an effective bond. In some cases all the passes on a multi-pass pipe weld may have to be TIG welding, if demand has high quality and code requirements.

Applications
MIG welding is an arc welding process in which a continuous solid wire electrode is fed through a welding gun and into the weld pool, joining the two base materials together.
A shielding gas is also sent through the welding gun and protects the weld pool from contamination.
In fact, MIG stands for “Metal Inert Gas”. The technical name for it is "Gas Metal Arc Welding" (or GMAW).
A Review: Parametric effect on mechanical properties and weld bead geometry o...IOSR Journals
Gas tungsten arc welding (GTAW) is high quality and high precision welding process which are
suitable for welding thin metals. Inert gas as helium and argon are used as a shielding gas to prevent the weld
bead from air, dust and other contaminations in welding. There are so many welding process parameter affect
the weld quality in GTAW. Important process parameter which mainly affect the weld quality are welding
current, arc voltage, welding speed, gas flow rate, heat input, gun angle, stand of distance and specimen
thickness. Important quality parameters in GTAW process are depth of penetration and weld bead geometry.
Depth of penetration and weld bead width both are affected by welding speed. As welding speed increases,
depth of penetration increases but weld bead width decreases. The weld joint quality can be assessed in terms of
weld bead geometry, mechanical properties and distortion. Post weld heat treatment is done to improve the
weld quality by solutioning and aging which results in refinement of grain size and thus, mechanical properties
of weld joint improved. Heat input effects the filler rod deposition rate in the form of droplets in weld bead. This
paper covers review of process parameters of GTAW and their effect on weld quality.

Immunizing Image Classifiers Against Localized Adversary Attacksgerogepatton
This paper addresses the vulnerability of deep learning models, particularly convolutional neural networks
(CNN)s, to adversarial attacks and presents a proactive training technique designed to counter them. We
introduce a novel volumization algorithm, which transforms 2D images into 3D volumetric representations.
When combined with 3D convolution and deep curriculum learning optimization (CLO), itsignificantly improves
the immunity of models against localized universal attacks by up to 40%. We evaluate our proposed approach
using contemporary CNN architectures and the modified Canadian Institute for Advanced Research (CIFAR-10
and CIFAR-100) and ImageNet Large Scale Visual Recognition Challenge (ILSVRC12) datasets, showcasing
accuracy improvements over previous techniques. The results indicate that the combination of the volumetric
input and curriculum learning holds significant promise for mitigating adversarial attacks without necessitating
adversary training.

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.
