This paper investigates suitability of friction surfacing (FS) for cladding AISI 1012 with Monel K500. FS trials were conducted by varying the spindle speed, axial pressure and the horizontal feed rate. The thickness and width of the coating were measured and the data were used to develop radial basis function network model relating the FS process parameters with the coating thickness and width. The model was used to analyze the variation of coating thickness and width. The coating thickness and width decreased with increase in spindle speed and horizontal feed rate, while they increased with increase in axial load. © 2017 Elsevier Ltd.

MONEL has very good corrosion resistance and is used for cladding marine components. However, to avoid hot cracking, nickel is first overlayed on the substrate before MONEL is overlayed. Friction surfacing (FS) is a new solid state technique that could be used to do the same cladding process without any nickel overlay. In this study, MONEL K500 was deposited on AISI 1012 substrate using FS. Three parameters namely the spindle speed, axial load and the horizontal feed rate were varied at five levels and FS trials were conducted. Thickness of the coatings was measured for all the surfacing trials. Response surface methodology is utilized to develop a mathematical model for the thickness of the surfaced layer in terms of the three chosen parameters. The significance of the spindle speed, axial load and the horizontal feed rate in producing coatings with good bond integrity is investigated. © 2017 IEEE.

R. V. Vignesh and Dr. Padmanaban R., “Modelling tensile strength of friction stir welded aluminium alloy 1100 using fuzzy logic”, in Proceedings of 2017 11th International Conference on Intelligent Systems and Control, ISCO 2017, 2017, pp. 449-456.[Abstract]


Friction stir welding (FSW) is a promising technique in which joints with high strength and minimal defects can be realized by adopting optimum process parameters. The prominent parameters are tool rotation speed, welding speed, shoulder diameter and pin diameter of the tool. In this study Mamdani fuzzy system was used to generate the model for predicting and exploring the influence of FSW process parameters on tensile strength of AA1100 joints. The FSW trials are conducted at various levels of process parameters according to central composite design. The study proved that the process parameters had significant effect on the tensile strength of friction stir welded joints. Crest parabolic variation trend was observed in tensile strength of the joints, with respect to the interaction effects of TRS, WS and SD. Increase in pin diameter had positive effect in increasing the tensile strength of the joints, for any change in TRS, WS and SD. Maximum tensile strength of 72.4 MPa was obtained at tool rotation speed of 1050 rpm, welding speed of 60 mm/min, shoulder diameter of 18 mm and pin diameter of 6 mm. The methodology given in this paper delivers a useful tool to assess the tensile strength of friction stir welded AA1100. © 2017 IEEE.

K. Chinnaraj and Dr. Padmanaban R., “Analytical Prediction of Residual Stresses in Cold Formed Steel Sections with Elastic - Perfectly Plastic Material Model”, in SAE Technical Paper, 2017.[Abstract]


The objective of this paper is to provide a reliable and robust mechanics based analytical approach for the accurate prediction of residual stresses in cold formed steel members. The forming residual stresses and associated equivalent plastic strains in cold formed corner sections are predicted with the assumption of elastic-perfectly plastic material model. The predicted analytical solution results are then compared with the existing analytical solution results. This work demonstrates that the exact estimation of forming residual stresses and equivalent plastic strains are possible with the inclusion of shift in neutral axis resulting from unequal thresholds of plasticity levels at the top and bottom surfaces of small radius corner sections. The predicted forming residual stresses and the associated equivalent plastic strains together define the initial conditions of corner sections for further non-linear structural behavior analysis of cold formed structures.

Dr. Padmanaban R., Muthukumaran, V., and Vighnesh, A., “Parameter Optimization for Friction Stir Welding AA1100”, in Advances in Mechanical Engineering, 2015.[Abstract]


Friction stir welding (FSW) has become a potential solid state joining technique with considerable advantages over conventional joining process. Defect-free friction stir welded joints with high joint strength are obtained when optimum process parameters are used. Although a large number of parameters govern the FSW process, the tool rotation speed, Welding speed and tool geometry are key parameters that influence the joint strength. In this work, a statistical model relating process parameters and the tensile strength (TS) of friction stir welded AA1100 joints is build using response surface methodology. The four independent variables are tool rotational speed (TRS), welding speed (WS), shoulder diameter (SD) and pin diameter (PD). Central Composite design is used and Analysis of Variance at 95% confidence level was applied to assess the adequacy of the developed model. Genetic algorithm is used for optimizing the parameters. The optimum process parameter values predicted using the genetic algorithm are as follows. Tool rotation speed: 1001.9 rpm; welding speed: 62 mm/min; shoulder diameter: 17.8 mm and pin diameter: 6.5 mm. The corresponding tensile strength of the joints is 73.1556 MPa

In the research work, an attempt is made to join nickel-based alloy 825 by employing CO2 laser beam welding. Successful full penetration weld joint of a 5 mm thick plate is achieved with a very low heat input of 120 J-mm−1. Narrow weld bead width of 0.6 mm at the root and 1.6 mm at the cap is observed fusion zone; the interface and base metal microstructures have been examined using both optical and scanning electron microscopic techniques to understand the microstructural changes which have occurred due to laser welding. A range of tests of Vickers micro hardness, tensile and impact tests had been performed on the weldment to ascertain the mechanical properties of the joint. Tensile failure at the base metal and a 180° root bend test conducted on the weldment ascertain the soundness of the weld joint produced. An attempt is made to correlate the microstructure and mechanical properties of the weldment. Intermetallics TiN and Al4C3 observed in the SEM/EDS analysis at the fusion zone are found to have improved the weld metal strength and hardness. © 2017 Canadian Institute of Mining, Metallurgy and Petroleum

Aluminium alloy 5083, widely used in marine applications, undergoes accelerated corrosion in sea water due to the aggressive reaction of chloride ions with the secondary phase particles and other intermetallics present in the alloy matrix. The corrosion rate of the alloy is also influenced by the temperature difference between the alloy and its environment. Friction stir processing (FSP) is a recent solid state processing technique for improving the surface properties of metals and alloys. In this study, an attempt has been made to explore the possibility of improving the corrosion resistance of AA5083 by FSP. FSP trials were performed by varying the tool rotation speed, tool traverse speed and shoulder diameter of the tool, as per face centered central composite design. The corrosion potential and the corrosion rate of friction stir processed AA5083 was studied using potentiodynamic polarization studies, at three different temperatures. Mathematical models based on polynomial–-radial basis function were developed and used to study the effect of process parameters on the corrosion potential and the corrosion rate of friction stir processed AA5083. FSP resulted in refinement of the grain structure, dispersion and partial dissolution of secondary phase particles in the matrix, which increased the corrosion resistance of the alloy.</p>

Pulsed TIG welding technology provides excellent welding performance on thin sections which helps to increase productivity, enhance weld quality, minimize weld costs, and boost operator efficiency and this has drawn the attention of the welding society. Maraging C300 steel is extensively used in defence and aerospace industry and thus its welding becomes an area of paramount importance. In pulsed TIG welding, weld quality depends on the process parameters used. In this work, Pulsed TIG bead-on-plate welding is performed on a 5mm thick maraging C300 plate at different combinations of input parameters: peak current (Ip), base current (I b ) and pulsing frequency (HZ) as per box behnken design with three-levels for each factor. Response surface methodology is utilized for establishing a mathematical model for predicting the weld bead depth. The effect of Ip, I b and HZ on the weld bead depth is investigated using the developed model. The weld bead depth is found to be affected by all the three parameters. Surface and contour plots developed from regression equation are used to optimize the processing parameters for maximizing the weld bead depth. Optimum values of Ip, I b and HZ are obtained as 259 A, 120 A and 8 Hz respectively. Using this optimum condition, maximum bead depth of the weld is predicted to be 4.325 mm.

A two-dimensional steady state visco-plastic model has been developed for friction stir welding of dissimilar metals using a commercial CFD code, FLUENT®. Volume of Fluid (VOF) approach is used to model the welding process of dissimilar metals. Initially, the model developed is validated against experimental measurements of Peel et al. (Metall Mater Trans A 37 A:2183–2193, 2006). Simulations were done for two different material combinations, AA 5083–AA 6061 and AA 2024–AA 7075. The temperature distribution and material flow around the tool is studied for different position of materials, process parameters, and tool profiles. It is seen that the peak temperature is generated on harder material side with change in position of materials. This is mainly because on harder material side more heat is generated due to viscous dissipation. The trivex pin profile is found to be better than circular pin profile by reducing welding traverse force and an efficient symmetric mixing of materials. © 2015, Springer-Verlag London.

Friction Stir Welding (FSW) is one of the latest solid state joining techniques being extensively used for joining many similar and dissimilar material combinations for structurally demanding applications and the results are promising. The weld qualities of the FSW joints depend on the process parameters used. Aluminum alloys AA2024 and AA7075 find applications in aircraft industries and pose challenges when joined using conventional fusion welding techniques. In this study, friction stir welding of dissimilar aluminum alloys AA2024-AA7075 is performed at different tool rotation speeds (TRS) and welding speeds (WS) as per central composite design with three factors and three-levels for each factor (face centred). Response surface methodology is used a mathematical model for predicting the tensile strength of the resulting joints was developed. The model is used to study the effect of the TRS and WS on the strength of the joints. The tensile strength of the joints is found to be affected by both the TRS and WS. Simulated Annealing is used to optimize the TRS and WS for maximizing the tensile strength of the joints. Optimum values of the TRS and WS are found to be 1087.6rpm and 14.12mm/min respectively. The maximum tensile strength of the joints is predicted to be 271.084MPa when these parameters are used.

Reuse of partially worn-out materials and parts is a philosophy now being applied in all manufacturing industries to achieve the goal of green manufacturing. High productivity cutting tools used in manufacturing industry are generally expensive. As such, the accurate assessment of remaining useful life (for reuse) of any given tool is of great significance in any manufacturing industry. This exercise will in turn reduce the overall cost and help achieve enhanced productivity. This paper reports the use of two soft computing techniques, namely, neuro fuzzy logic technique and support vector regression technique for the assessment of remaining useful life (RUL) of cutting tools. In this work, experiments are conducted based on Taguchi approach and tool life values are obtained. Tool life values are predicted using the aforesaid two soft computing techniques and RUL obtained from these values are compared. © 2013 Springer Science+Business Media New York.

Sesha Saty, “Numerical modelling of thermal phenomenon in friction stir welding of aluminum plates”, IOP Conference Series: Materials Science and Engineering, vol. 149. p. 012208, 2016.[Abstract]


Friction stir welding (FSW) is a solid state welding process with potential to join materials that are non weldable by conventional fusion welding techniques. The study of heat transfer in FSW aids in the identification of defects like flash, inadequate heat input, poor material flow and mixing etc. In this paper, transient temperature distribution during FSW of aluminum alloy AA6061-T6 was simulated using finite element modelling. The model was used to predict the peak temperature and analyse the thermal history during FSW. The effect of process parameters namely tool rotation speed, tool traverse speed (welding speed), shoulder diameter and pin diameter of tool on the temperature distribution was investigated using two level factorial design. The model results were validated using the experimental results from the published literature. It was found that peak temperature was directly proportional to tool rotation speed and shoulder diameter and inversely proportional to tool traverse speed. The effect of pin diameter on peak temperature was found to be trivial.

In this paper, hybrid laser-arc welding process has been studied based on the relative position of the laser and the arc (i.e. laser-leading and arc-leading arrangement) and, the effects of welding parameters, such as the laser power, arc current, arc voltage and the welding speed on the weld bead were investigated. The study indicates that the welding direction has a significant effect on the weld bead and weld pool behaviour. The result shows that laserleading configuration shows better bead characteristics when compared to arc-leading configuration. This is because in the laser-leading case molten metal flow is inward, while in the arc-leading case the metal flow is outward leading to variation in solidification front resulting in lack of synergic effects of both processes.
