TIG welding only allows for a few millimeters of penetration depth. This limitation of TIG welding can be overcome by a new advanced TIG technique called activated tungsten inert gas welding (ATIG). This new approach of TIG welding allows up to 8 cm to 12 cm of penetration depth. The demand for activated tungsten inert gas welding (ATIG) has risen in the past few years, and it has been rooted as a viable alternative to subtractive manufacturing. According to research, ATIG weldments have mechanical qualities that are comparable to other more expensive welding techniques. ATIG offers significant cost savings and a higher production rate when compared to other welding techniques. ATIG, on the other hand, has a number of drawbacks, including high residual slag, poor mechanical properties, and low corrosion resistance. As a result, more research is needed into ATIG weld parameter optimization, ATIG process simulation, and post-weld heat treatment to address the aforementioned issues. In light of the foregoing, the focus of this study will be on ATIG welded sample experimental research, modeling, optimization, and corrosion behavior. Furthermore, the study will consider the significant difficulties associated with metallurgical properties, such as detrimental secondary phase formation, carbon migration, hot cracking, weld distortion, and residual stresses that must be removed or reduced for the weld to be qualified.

The quality of work is mostly depending on the skill of the labor work in manual plastering process. The solution of these problems is just to automate the process, so that there will be a saving of period and cost and getting good plaster finishing to the walls. The plastering machine can plaster the walls automatically and very smoothly. Due to which the process will fast and there will be saving of cost and time this will helps to reduce the total cost, total time which ultimately responsible for the growth and hence the progress rate of a country is going to increase.

Even in completely controlled process, defect in casting are observed and hence casting process is also known as process of uncertainty which challenges explanation about the cause of casting defects. In order to reduce warpage defects and problem related to warpage defects, the study is aimed in this paper. Many products are made by using casting process as it is economical and has the ability to produce intricate shapes. So far, casting defect analysis has been carried out using techniques like finite element method and modulus method to reduce defects. . Casting software can optimize the virtual castings so that real castings can be produced 'right first time and every time'.

In this study, the component from industry i.e. manhole cover is leading to premature failure of warpage or distortion. Hence, there is requirement of optimizing the appropriate gating/risering system. In this paper, the actual gating/risering system is simulated to minimize the warpage defect occurring in the industry while manufacturing. Hence, the simulation for optimizing better gating/risering system is done by using AutoCAST-X software which is based on Vector Gradient Method (VGM) for defect minimization.

Distortion can be defined as deviation from the natural, normal, or original contour, shape or size due to application or removal of forces [1]. Distortion can be reduced but never be completely eliminated. It aims at reducing the bend occurring in the washers due to addition of external forces at time of punching operation. Many bearings contains washer as a major component which is required to have very less distortion. Distortion in washer can prove very fatal for the life and working of bearing. Usually thrust bearings are made up of the washers containing needles and virol as main elements. This paper showcase the techniques developed to control the distortion so as to minimize the bad effects on the bearings. Distortion is usually caused in the washers having larger internal and external diameters .Proper strip holding devices and lubrication if required should be used to reduce the bend...

The properties of biodiesel are found similar to that of diesel. Many researchers have experimentally evaluated the performance characteristics of conventional diesel engines fuelled by biodiesel and its blends. However, experiments require enormous effort, money and time. Hence, a cycle simulation model incorporating a thermodynamic based single zone combustion model is developed to predict the performance of diesel engine. A comprehensive computer code using “C” language was developed for compression ignition (C.I) engine. Combustion characteristics such as cylinder pressure, heat release, heat transfer and performance characteristics such as work done, brake power and brake thermal efficiency (BTE) were analyzed. On the basis of first law of thermodynamics the properties at each degree crank angle was calculated. The simulated combustion and performance cha...
