Weld Quality Prediction of Mild Steel Pipe Joint during Shielded Metal Arc Welding through fuzzy Logic

The present paper describes fuzzy logic simulation of shielded metal arc welding (SMAW) process to predict the Quality of weld joint. It describe the quality of weld joint & effect of welding current, voltage and welding speed on tensile strength of shielded metal arc pipe welded mild steel joints. An ERW Mild steel pipe I S 1239 of 6 mm thickness and 150 mm diameter were used as the base mater...

Application Of Artificial Neural Network In Predicting The Weld Quality Of A Tungsten Inert Gas Welded Mild Steel Pipe Joint

The weld quality of Tunston inert gas welded joint has been investigated to identify the most economical weld parameters that will bring about optimum properties. Artificial neural network, has been used in the prediction and optimization of the Tunston inert gas weld of mild steel pipes. Neural network model was generated using the Levenberg-Marquardt algorithm with feed ward back propagation ...

The influence of pipe length in direct numerical simulation

A direct numerical simulation (DNS) of fully developed turbulent pipe flow is performed at Reτ ≈ 170 and 500 to examine the effect of the streamwise domain length on the convergence of turbulence statistics. Computational domain lengths vary from the πδ to 20πδ. Lower order statistics such as mean flow, turbulence intensities, Reynolds stress, correlations and higher order statistics including ...

Transformation Plasticity in Steel Weld Metals

Professor Ulrich Dilthey’s passion for the science and technology of joining processes is amply reflected in the enormous archive of published work which will forever serve the community. It is a pleasure therefore to be able to present this small story as a tribute to someone who has been a scholar, a gentleman and a leader in this most difficult of subjects. The matter of our everyday world i...
