Experimental investigation of magnetic arc blow in plasma arc cutting

Modeling the Plasma Arc Cutting Process Using Ann

This paper deals with modeling of plasma cutting process using artificial neural network (ANN). The objective was to develop an ANN model in order to predict the ten-point height of irregularities (Rz) in terms of three input parameters, cutting current, plate thickness and cutting speed. To this aim, a feed-forward backpropagation ANN was developed and trained using the experimental data. Afte...

Influence of Gliding Arc Cold Plasma Based on Argon, Helium and Compact Air on Bactria Around the Wound: Experimental Investigation

Background: Today, the use of cold plasma and its applications have taken into consideration. The plasma is a mixture of active oxygen and negative ions. This compound has a practical effect on the elimination of all types of bacteria and viruses. The cold plasma feature is essential and very useful in disinfecting processes. In this investigation, we plan to study the effect of gliding arc pla...

Metal Transfer and Arc Plasma in Gas Metal Arc Welding

This article analyzes the transient complex heat transfer and fluid flow in molten metal and arc plasma during the gas metal arc welding process. The model predicts the formation, growth, detachment, and transfer of droplets from the tip of a continuously fed electrode under the influences of several competing forces including gravity, electromagnetic force, arc pressure, plasma shear stress, a...

Experimental Design and Performance Analysis in Plasma Arc Surface Hardening

In this paper, the experimental design of using the Taguchi method is employed to optimize the processing parameters in the plasma arc surface hardening process. The processing parameters evaluated are arc current, scanning velocity and carbon content of steel. In addition, other significant effects such as the relation between processing parameters are also investigated. An orthogonal array, s...
