A State of the Art Review on Modelling Work Carried Out During Friction Stir Welding
Authors: Kumar Singh Manish , Kumar Porwal Rajesh , Mishra Sanjay 
Published: November 2019

Abstract
Welding of soft materials like aluminium, copper by fusion welding process is not achievable due to the generation of defects. These materials have a wide area of industrial applications. Therefore, their welding is one of the most challenging tasks in the joining industries. Since welding is used to join two materials or parts of materials of similar or dissimilar nature, therefore, the repudiation of the welded product due to poor weld quality is not acceptable in the modern joining industries. Friction stir welding can minimize these defects because in this process there is no melting of workpiece occurs. In the past, many researchers have examined a number of approaches to enhance the weld joint properties. The observational and notional analysis shows weld joint quality can be enhanced remarkably with the appropriate choice of process parameters. This article analyses the research work accomplished by various researchers in the field of modelling of the friction stir welding operation.

Published: November 2019

Abstract
This article reports the fabrication and investigation of sliding wear properties of Linz-Donawitz (LD) slag reinforced epoxy composites. Hand lay-up technique is used for composite fabrication. LD slag is varied from 0 to 30% by weight and sliding wear tests are performed. The sliding wear performance of these composites is evaluated at various sliding velocities and normal loads. It is found that the incorporation of increased LD slag content resulted in significant enhancement in sliding wear resistance. This work also shows that LD slag content and sliding velocity are the most influencing factors as far as the minimization of specific wear rate is concerned.

Authors: Porwal Rajesh , Maurya Ranu 
Published: November 2019

Abstract
The era is shifting towards the manufacturing idea of converting raw form of material into finalized part in minimum step and lesser machining operation. Manufacturing processes like 3D printing and additive manufacturing are achieving the criteria but they requires high capital investment and are sophisticated in its operation which need next to zero possibility of error. Alloying of materials yield high derivative properties like hardness, temperature resistance and extreme strength to weight ratio like in Titanium, Nickel and their alloys and super alloys. Specialized feature at micro level, complex and intricate geometries in the part are difficult to produce via traditional machining processes than non-contact machining process at cost effectiveness. This paper reviews the modelling related studies done in the processing of Titanium alloys through Wire-micro electrical discharge machining (Wire-μEDM) process. Most of the research done in the Wire EDM domain, experimented with the wire of copper and brass with diameter range in microns, thus resulting micro-machining phenomenon. Since Ti alloys find the most of the applications in field of aerospace, automobile, nano tech due to excellent performance at elevated temperature and pressure, than other alloying materials. The summarized should provide an overview on modelling techniques used by the re-searchers for measuring and predicting the parametric values for the optimization of WEDM process.

Published: November 2019

Abstract
In the current work, pure Mg and two Mg alloys (AZ31 and AZ91) were selected and processed by friction stir processing (FSP). After FSP, the effect of microstructure and the corroding environment on the degradation behaviour of processed and unprocessed materials in two different solutions (0.9M NaCl and Ringer’s solution) by immersion method. The samples after immersion were characterized by X-Ray diffraction (XRD) method and electron microscopy. Interestingly, corrosion rate of FSPed samples was observed as decreased compared with unprocessed condition when immersed in Ringer’s solu-tion. On contrary, the corrosion rate of FSPed samples was noticed as increased compared with unprocessed condition when immersed in 0.9M NaCl solution. The results strongly suggest that the effect of smaller grain size and the ion concentration of the simulated physiological solution have a significant influence on the degradation behaviour of Mg alloys which must be considered while developing Mg based biodegradable implant materials

Published: November 2019

Abstract
Laser Assisted Electrochemical Machining (LAECM) has proven its advantages and applications over almost all the range of conductive materials. It offers its adroitness to generate simple shapes to complex shapes from macro to micro machining. Laser assisted ECM is a hybrid approach of machining which has been manifested to obtain improved results in terms of surface integrity, thermal damage, geometrical tolerance and material removal rate. Laser assisted Electrochemical Machining (LAECM) is a hybrid machining process in which laser enhances the electrochemical dissolution process by increasing the temperature and hence the current density of the electrolyte. Laser helps to remove material from the particular machining zone and stray machining effect is reduced and thus improves the precision and efficiency of LAECM, also productivity. New route of laser assisted hybrid machining processes has been built in the past decade by few of the researchers to reduce the intrinsic problems of ECM. This paper reviews on the investigation into LAECM process. The article also highlights various possibilities and applications of LAECM process. There are various challenges in LAECM process which have been also discussed in this paper.

Authors: Mahanta T , Satpathy M P , Swain A 
Published: November 2019

Abstract
In the era of composites and ceramics, reinforced metal matrix composites have paved its way to many engineering fields due to its superior mechanical and thermal properties. Zirconia (ZrO2) is one such most researched ceramics, which leads to excellent bond strength, grain refinement, and improved tribological aspects of the composite. To simplify the post mold machining of such new composites, the present work emphasizes on the prediction of cutting force for different composition of ZrO2 in an Aluminum metal matrix composite reinforced with SiCp and Graphite. The purpose is to streamline the complex analysis of induced cutting force during turning with quantifiable machining parameters for the developed composite. The influence of two machining parameters such as depth of cut and feed rate are analyzed with an increase in ZrO2%. For the better prediction of the cutting force, the artificial intelligence techniques like adaptive neuro-fuzzy interface system (ANFIS) backed by a heuristic genetic algorithm (GA) is employed. The comparison between the predicted model values with the experiment results is exhibited ±1% error having R-square value 0.9927. The interaction plot and soft computing model stood in equal agreement that with the rise in both depth of cut and feed rate, the cutting force value decreases. Again for an increase in ZrO2% and feed rate, a definite increase in cutting force is observed. The effect of an increase in ZrO2% in the composite over the machining parameter is suggested through the main effect plot, which stands in equal agreement with the GA model.

Published: November 2019

Abstract
The aim of this research is to design and to develop a computer controlled low-cost underwater welding setup for shielded metal arc welding (SMAW) process to work in dry as well as in wet welding conditions. Investigations of the microstructure and mechanical properties of the welded joints made from AISI 1010 steel plates using this setup, in air, tap water, and saltwater working environment, respectively, have been carried out. Weld bead geometry, microstructure, ultimate tensile strength (UTS), ductility, impact strength and Vickers microhardness of air and wet welded joints have been characterized and compared. The general weld bead size is quite dissimilar for air, tap water and salt water welded joints. The tap water and salt water welds seem to be wider with a slightly higher weld penetration with lower reinforcement. The maximum value of the the average UTS of the welded sample as per ASTM was 485.74 MPa. The experiments showed that the maximum percentage of elongation of samples welded in different conditions is 8.06 % and the maximum value of the average impact strength of 25.64 J was found in case of air welds. The microhardness value of fusion zone (FZ) was greater than base metal (BM) in all the welded samples. It was noted maximum up to 310.8 HV10 at coarse grain heat affected zone (CGHAZ) of tap water welds. The mechanical properties of the salt water welds deteriorated due to porosity, slag inclusion, undercut, increase in hydrogen and oxygen content in the welds.
