Pressure vessels are critical equipment used in industries for storing liquids or gases at a pressure significantly different from ambient conditions. Porosity is one of the major weld defects in pressure vessels that leads to failure during inspection and as well as during its service. Gas Metal Arc Welding (GMAW) process is widely used in industries to fabricate pressure vessels using carbon steel “IS 2062 E250BR” material for storing compressed air. The main objective of this article is to reduce the porosity defect in the longitudinal seam (LS) welding of the pressure vessels. Detailed analysis is carried out to identify the parameters which are influencing the porosity defect. Central Composite Design (CCD) and Response Surface Methodology (RSM) approaches are used to find the optimum value of the weld parameters which produce weld without porosity or any major defects in the pressure vessel. An experimental setup has been established and welding experiments have been conducted under a controlled environment. Experiments were conducted without any external disturbances ensuring clean weld surface and filler wire without any moisture, rust, oil, and the presence of any organic materials. For all the weld specimens, visual and radiography examinations were carried out to identify the severity of porosity. A porosity index is proposed in this study for conducting statistical analysis. Statistical analysis shows current, travel speed, gas flow rate, and torch angle have a linear relationship and stickout distance has a nonlinear relationship with porosity. In square term, stickout distance has a significant influence on porosity defect. In two-way interaction studies, current and gas flow rate, current and torch angle, and travel speed and torch angle have a significant influence on porosity. Confirmatory tests were carried out to validate the optimum weld parameters obtained in this study.

In this paper, a study has been carried out to find the influence of oil injection parameters on the performance of diesel powered screw air compressor which is used in water well application. Oil injection parameters considered in this study are oil injection orifice size, engine speed and oil injection pressure. Performance of the screw compressor is evaluated by measuring the fuel consumption, discharge oil temperature and free air delivery. An experimental design is created using Central Composite Design (CCD). The lower and upper bound of input parameters were fixed based on the application requirement and theoretical estimation. The experiments were performed as per the experimental design and output responses were recorded. The significance of the input parameters on output responses was studied using Analysis of Variance (ANOVA). Response Surface Methodology (RSM) is employed to study the optimum range of parameters to obtain the best performance of the compressor in drilling and idling cycles. The best performance is achieved by setting engine speed value of 1490 rpm, injection orifice diameter of 9.5 mm and an oil injection pressure of 135 psi(g) in the drilling cycle. For idling cycle, an engine speed of 1260 rpm, oil injection orifice diameter of 8.5 mm and an oil injection pressure of 150 psi(g) result in the best performance of compressor in idling cycle. The optimized parameters are validated by conducting confirmatory tests. The water well screw compressor operated with optimum parameters results in considerable savings in the fuel consumption. A lubrication circuit is designed incorporating the optimum nozzle size obtained in this study.

It is vital to improve productivity with cutting edge technology for any manufacturing or service industry. Quality with quantity helps a company to stay in competition. Technology has developed greatly to meet the customers’ demand. The elimination of waste with increased productivity leading to hike in profit should be the target of the manufacturing sector. The tyre manufacturing company in which the study was carried out requires reduction in non-value added activities, bottlenecks and processing time to increase productivity. The paper presents the current process simulation undergone in a tyre manufacturing plant. The simulation study found that the actual figures produced in the plant matched the 1170 units per day throughput. The simulation reveals the calendering process as the bottleneck present in the plant. The Pareto analysis used confirms the bottleneck simulation analysis result. Root causes for problems were identified using 5 why analysis and the cause-effect diagram. Solutions were suggested to reduce process times viz the bottleneck experimented, which show an increase in throughput of the tyre manufacturing plant. The bottleneck can be eliminated by modifying the calendering machine to increase productivity by 15.81%. The breakeven time for installation costing 3.5crores will be for 88 days. By going with an automated temperature measuring system, the total productivity can be increased by 18.8% from the existing scenario.

This paper focuses on discrete event simulation of a manufacturing unit using ARENA software. The simulation was carried out with an objective to study the flow of aluminium brake brackets in the factory and find out the bottlenecks and also to calculate the productivity and workforce requirements in the unit. The process flow chart of the aluminium bracket was drawn and processing time of each process was calculated using ARENA input analyzer tool and then fed into the software and simulated. For optimization of the results the other tools available in arena like Process Analyzer (PAN) and Opt Quest were used. The bottlenecks were found and a better model was suggested in order to overcome them. In the new (suggested) model, the productivity was found to have increased by 6% and the workforce requirements decreased by 8.33% when compared with the existing (actual) factory model. The method followed in this paper can be used to design process as well as factory layouts for better efficiency of workforces, to achieve optimal productivity and better use of resources.

Diffusion bonding is one of the solid state joining process, in which two clean metallic surfaces intended for joining were brought into contact at elevated temperatures under optimum pressure. In this work, an attempt is made to study the analysis and simulation of the two dissimilar materials Titanium alloy (Ti-6Al-4V) and Stainless Steel (SS304) which is having a wide application in the area of aerospace. Structural analysis was carried out to determine the equivalent stress, elongation and total deformation of the welded joint. Explicit Dynamics analysis using Ansys was used to predict the strength of Ti-6Al-4V/SS304 diffusion bonded joint. The result indicates that Equivalent stress is attained at 1.393GPa and total deformation is 0.00275m obtained at a time 0.000041seconds. The analysis shows that the fracture occurs in the region of titanium alloy and not in the region of HAZ.

Cooling towers are the heat transfer devices commonly found in industries which are used to extract the high temperature from the coolants and make it reusable in various plants. Basically, the cooling towers has Fills made of PVC sheets stacked together to increase the surface area exposure of the cooling liquid flowing through it. This paper focuses on the study in such a manufacturing plant where fills are being manufactured. The productivity using the current manufacturing method was only 6 to 8 fills per day, where the ideal capacity was of 14 fills per day. In this plant manual labor was employed in the manufacturing process. A change in the process modification designed and implemented will help the industry to increase the productivity to 14. In this paper, initially the simulation study was done using ARENA the simulation package and later the new design was done using CAD Package and validated using Ansys Mechanical APDL. It's found that, by the implementation of the safe design the productivity can be increased to 196 Units. © Published under licence by IOP Publishing Ltd.

A novel porosity detection technique from the voltage and current transients is introduced in this paper. An online weld monitoring that detects the porosity at an earlier stage is much demanding in the industry due to their adverse effects on structural integrity. In this research work, control chart and probability density distribution have been employed as tools to detect arc instability and weld porosity. The results showed that the pattern of probability density distribution changes for the defect and defect-free welds significantly. The mean and standard deviation control charts plotted with voltage clearly distinguished the quality of the weld based on sample points spread within or outside the control limits. For minute internal porosities, the sample points at the corresponding region in the standard deviation control chart were outside the limits whereas it is well within the control limits in the mean control chart. Inspector can predict the presence and near location of porosity using these tools by simple mathematical calculations easily and instantly. The results proved that the developed approach is successful and promising for the weld inspection.

Welding is one of the major metal-joining process employed in fabrication industries, especially in manufacturing of boilers and pressure vessels. Control of weld quality is very important for such industries considering the severe operating conditions. Industries are looking for some kind of real-time process monitoring/control that will ensure the weld quality online and prevent the occurrence of defects. In this paper an attempt is made to establish a correlation between the current and voltage signatures with the good weld and weld with porosity and burn through defect during the welding of carbon steel using gas metal arc welding (GMAW) process. Experimental setup has been established and experiments were conducted using a welding robot integrated with GMAW power source. The experimental setup includes online current and voltage sensors, data loggers, and signal processing hardware and software. Welding conditions are carefully designed to produce good weld and weld with defects such as burn through and porosity. Current and voltage signatures are captured using data acquisition system (DAS). Software has been developed to analyze the data captured by the DAS. Statistical methods are employed to study the transient data. The probability density distributions of the current and voltage signature demonstrates a good correspondence between the current and voltage signatures with the welding defect. © 2017, King Fahd University of Petroleum & Minerals.

Welding is one of the most common metal joining techniques used in industry for decades. As in the global manufacturing scenario the products should be more cost effective. Therefore the selection of right process with optimal parameters will help the industry in minimizing their cost of production. SA 106 Grade B steel has a wide application in Automobile chassis structure, Boiler tubes and pressure vessels industries. Employing central composite design the process parameters for Gas Tungsten Arc Welding was optimized. The input parameters chosen were weld current, peak current and frequency. The joint tensile strength was the response considered in this study. Analysis of variance was performed to determine the statistical significance of the parameters and a Regression analysis was performed to determine the effect of input parameters over the response. From the experiment the maximum tensile strength obtained was 95 KN reported for a weld current of 95 Amp, frequency of 50 Hz and peak current of 100 Amp. With an aim of maximizing the joint strength using Response optimizer a target value of 100 KN is selected and regression models were optimized. The output results are achievable with a Weld current of 62.6148 Amp, Frequency of 23.1821 Hz, and Peak current of 65.9104 Amp. Using Die penetration test the weld joints were also classified in to 2 categories as good weld and weld with defect. This will also help in getting a defect free joint when welding is performed using GTAW process.

A key factor in the performance of Gas Metal Arc welding (GMAW) is the feedability of the filler wire. Variations in the wire feed speed (WFS) are caused by adverse conditions during welding. These include damaging effects such as "stick-slip" motion of the welding wire, premature wear of the contact tube and, in general, the conduit cable usage during welding. Experiments were conducted to study these issues. The welding parameters such as arc current and voltage were captured by using data logger and the stick-slip effect was analyzed. It was observed that arc waveforms were found to have significant influence because of the stick-slip effect. The corresponding fusion characteristics of the weldments were studied. The voltage change was suggested to specific conduit cable configuration.

Welding is one of the major joining processes employed in fabrication industry, especially one that manufactures boiler, pressure vessels, marine structure etc. Control of weld quality is very important for such industries. In this work an attempt is made to correlate arc sound with the weld quality. The welding is done with various combinations of current, voltage, and travel speed to produce good welds as well as weld with defects. The defects considered in this study are lack of fusion and burn through. Raw data points captured from the arc sound were converted into amplitude signals. The welded specimens were inspected and classified into 3 classes such as good weld and weld with lack of fusion and burn through. Statistical features of raw data were extracted using data mining software. Using classification algorithms the defects are classified. Two algorithms namely, J48 and random forest were used and classification efficiencies of the algorithms were reported.

The quality of weld depends upon welding parameters and exposed environment conditions. Improper selection of welding process parameter is one of the important reasons for the occurrence of weld defect. In this work, arc sound signals are captured during the welding of carbon steel plates. Statistical features of the sound signals are extracted during the welding process. Data mining algorithms such as Naive Bayes, Support Vector Machines and Neural Network were used to classify the weld conditions according to the features of the sound signal. Two weld conditions namely good weld and weld with defects namely lack of fusion, and burn through were considered in this study. Classification efficiencies of machine learning algorithms were compared. Neural network is found to be producing better classification efficiency comparing with other algorithms considered in this study.

In this work, an experimental setup has been established consisting of a cylindrical grinding machine with piezo-electric sensor for capturing acoustic emission and its related hardware and software for signal processing. Acoustic signals are captured for the entire grinding cycle until the abrasive grains of the girding wheel become dull. Surface roughness produced by the process is recorded at fixed time intervals from the beginning to the end of the grinding cycle. Various features of the acoustic emission signatures such as root mean square, amplitude, ring-down count, average signal level are extracted from the time-domain are compared and correlated with the surface roughness generated by the grinding wheel on the work-piece. Good condition and dull condition of the grinding wheel is predicted using machine-learning techniques such as decision tree, artificial neural network, and support vector machine. Results indicate that there is a strong correlation exiting between the acoustic emission features and the surface roughness produced by the grinding process. Support vector machine trained with cubic kernel is appears to be predicting the grinding tool condition with greater accuracy comparing with decision tree algorithm and artificial neural network considered in this study.

The quality of the weld is most important in industries manufacturing boilers and pressure vessels which will work in severe operating conditions. In an automated environment, developing a process monitoring and control system will ensure the weld quality and prevent the occurrence of defects. In this paper, an attempt is made using the decision tree algorithm to establish a correlation between the current and voltage signatures with the quality of the weld. Carbon steel plates are welded using GMAW processes and experimental design is established to obtain weld without any defects (good weld) and weld with porosity and burn-through defects. “KUKA” robotic GMAW welding setup integrated with “Fronius” power source is used in this study for experimentation. “TVC” data acquisition system is used to capture the current and voltage signatures. Statistical features are extracted from the current and voltage signatures. Decision tree algorithm with split criterions such as “gini index”, “towing”, and “deviance” are used to classify the weld defects. Results indicate the effectiveness of decision tree algorithms in classifying the weld defects using the current and voltage signatures.
