The main purpose of this research is to study the optimal process parameters for thermal friction drilling process on AISI 304 stainless steel. The experiments were conducted based on Taguchi experimental design method, and the multiple performance characteristics correlated with the resultant axial force, radial force, hole diameter dimensional error, roundness error, and bushing length, were investigated by fuzzy logic technique. The significant process parameters that most intensively affected the multiple performance characteristics and the optimal combination levels of process parameters were determined through the analysis of variance and the response graph. A test rig was manufactured at Shoman Company ‒ Egypt to perform the experimental work, and the tools were offered by Flowdrill Company ‒ Germany. Experimental results confirm that this approach is simple, effective and efficient for simultaneous optimization of multiple quality characteristics in thermal friction drilling process, as the bushing length produced is more than five times the workpiece thickness.

Effect of process parameters using friction stir processing /welding of steel...Husain Mehdi
Microstructural changes and flow of material have be comprehensively studied by many researchers. A lot of studies have been conducted by changing the process parameters such as axial load, feed, speed of the tool, tool geometry, tool tilt angle etc. to find the optimum process parameters. Friction stir welding can be applied on various materials such as aluminum, manganese, copper. Till date majority of the research and development was done on aluminum alloys. This is so because Al alloys are easy to deform at relatively low temperatures (approximately below 550 Celsius). Also, they are easier to weld as compared to other materials. But these days a lot of studies are being conducted on carrying out friction stir processing on steel. This process improves mechanical properties like tensile strength, ductility, micro-hardness etc.

Friction stir Processing (FSP) is a new innovative technology developed based on the principle of Friction Stir Welding (FSW) technique.
In FSP, the ceramic particulates are reinforced into the base metal by adding it into the groove and Friction Stir Processing (FSP) is performed.
In this study, the aluminum alloy 6061 is chosen as the base metal, alumina and graphite Nano powder as reinforcement.
The process parameters such traverse speed of 64 mm/min and the tool rotational speed of 1060 rpm and tilt angle of 2deg were selected, The Friction Powder Processing was carried out on vertical milling machine.
New parameters such as powder type and number of passes were involved and we also study the effect of heat treatment.
The influence of FSP was checked using some tests such as the microstructure analysis that was carried out using optical microscope (OM) and the mechanical characteristics were analyzed using tensile test and hardness test.
The micrograph results revealed that powder particulates were evenly distributed in the stir zone and reduction in grain size also observed; the reason for the grain size reduction was stirring action of the FPP tool’s pin.
The tensile strength results showed a significant improvement in strength by a percent of
50% compared to base metal but when T6 heat treatment is applied, the tensile strength decreased.

Prediction of Weld Quality of A Tungsten Inertr Gas Welded Mild Steel Pipe Jo...IJERA Editor
The weld quality of tungsten inert gas (TIG) welded joint has been investigated to identify the most economical weld parameters that will bring about optimum properties. Response surface methodology has been used in the optimization of the tungsten inert gas weld of mild steel pipes. Response surface methodology, based on the central composite face centered design was generated for the purpose of optimization of the weld quality.All the process parameters have desirability of 1. Tensile strength response for this solution have a desirability of 0.910595 and the yield strength of 0.59. Result showed that minimizing current and voltage an average tensile strength of 535.452MPa and yield strength of up to 408.74MPa can be achieved, while keeping gas flow rate and electrode diameter within the range of test. It was also deduced that tensile elongation of the TIG weld is not influenced by the process parameters selected for the purpose of this study.
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.

Tungsten inert gas (TIG) welding in which the arc is formed between a pointed tungsten electrode and the work piece in an inert atmosphere of argon or helium but the activated TIG welding is that in which oxides of fluxes are used on work piece also called A-TIG. Current and voltage can have profound effect on the material in terms of strength and hardness. This research aims at the study of using conventional TIG (tungsten inert gas) and activated TIG welding process to investigate the effect of different levels of factors (current, voltage, gas flow rate, electrode diameter) on the mechanical properties of the mild steel using mixture of MgO and CaO flux. Mild steel specimens were used during the experimentation. The results of conventional TIG have been compared with the activated TIG welding. The method of design expert is used to carry out the experimentation. Moreover it is observed that there is decrease in hardness of weld but the quality of weld is increased as compared to conventional TIG welding.

techniques to determine the optimal process parameters for
submerged arc welding (SAW).The planned experiment work is
conducted in the semiautomatic submerged arc welding machine
and signal to noise ratios have been computed .the contribution of
each factor has been validated by analysis of variance(ANOVA).
The results of the present investigation indicate that the welding
voltage is the most significant parameter that controls the bead
penetration as compared to other controlling parameters. The
contribution of voltage, current welding speed and nozzle-to-plate
distance have been found to be respectively: 60.8%, 9.86%,
3.54% and 13.8%. Optimum results have been obtained by using

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.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
