Abstract Angular Distortion is a major problem and most discussed among the different types of distortion occurring in the welded joints. The main cause of angular distortion is non-uniform transverse shrinkage along the depth of welded plates. The angular distortion restriction may leads to high residual stresses, but can be reduced by providing initial angular distortion in negative direction. So for this the value i:e magnitude of angular distortion must be known. It is difficult to obtain a complete analytical solution to predict the angular distortion. In this paper the process parameters affecting the angular distortion are studied. The Fuzzy Logic is used for the prediction of angular distortion with the multipass Gas Metal Arc Welding …show more content…

Fuzzy rule or IF-Then rule plays a central role in all fuzzy logic applications. Calculus of fuzzy rules called fuzzy dependency & command language (FDCL) is effectively one of the principle constituents but not used explicitly in the toolbox. The trend that is growing in visibility relates to the use of fuzzy logic in combination with neuro compacting & genetic algorithm which is the soft computing process. Unlike the traditional and hard computing, soft computing process accommodates the imprecision of the real world. Soft computing plays an important role in the conception & design of the systems whose machine IQ is much higher than that of the system designed by the conventional method. Fuzzy logic is all about the relative importance of precision, how important is it to be exactly correct when a rough answer will do. Fuzzy logic is an emerging area of research because it does a good job of trading off between significance & precession. Fuzzy is something that humans have been managing for a very long time. Fuzzy logic is the convenient way for mapping of input space to the output space which is starting point of everything. Loti Zadeh who is said to be the father of Fuzzy logic states or said that; in almost every case you build the same product without fuzzy logic, but fuzzy is tool …show more content…

As stated in the previous study in the reference papers, Fuzzy is a logical system which is an extension of multi valued logic. Fuzzy rule or IF-Then rule plays a central role in all fuzzy logic applications. Fuzzy logic is all about the relative importance of precision, how important is it to be exactly correct when a rough answer will do. Fuzzy logic is a useful area of research because it does a good job of trading off between significance & precession. Fuzzy is something that humans have been managing for a very long time and also it is faster and cheaper. Fuzzy logic is simple to understand and is flexible to use also it is very powerful tool for dealing quickly and efficiently with imprecision and nonlinearity. D. Applications of Fuzzy Logic Fuzzy Logic is a soft computing method which is very simple and flexible so it is been used in wide range of applications as, Coal Power Plant, Water Treatment Systems, AC Induction Motor, Fraud Detection, Customer Targeting, Quality Control, Nuclear Fusion, Truck Speed Limiter, Toasters, Photocopiers, Vacuum Cleaners, Credit Assessment, stock prognosis. Mortgage Application, Humidifiers, Domestic Goods - Washing Machines/Dryers, Microwave Ovens, Consumer Electronics – Television, Still and Video Cameras - Auto focus, Exposure and
