We developed the laser oxyfuel and oxyflame hybrid (LOXAFH) cutting method which has
the potential to break the limit by integrating laser and oxyfuel cutting methods. The LOXAFH …

Recent use of ion currents as a sensing strategy in the mechanized oxyfuel cutting process
motivated a series of studies which revealed that the steel work piece contributes secondary …

We present the first published record of electrical phenomena in the oxyfuel cutting torch
flame while cutting a steel work piece. Measurements of the voltage-current characteristic …

This is a study of the suitability of preheat flame electrical resistance as a potential method
for measuring the standoff distance an oxyfuel cutting torch and a work piece. Careful …

ABSTRACT A novel variation of the Langmuir probe for spatially resolved ion density
measurements in a dense flowing plasma is presented. The technique uses a spinning disc …

Experiments controlling for work surface temperature and chemical activity under an oxyfuel
cutting torch flame reveal that ion currents in the flame can double or even triple due to …

This paper presents numerical and asymptotic analytical solutions for the current–voltage
characteristic of a flame using a one-dimensional ion transport model with boundary …

Electrical property is a key factor to determine performance and characteristic of welding arc.
In this study, the electrical property distribution of welding plasma arc was investigated by …

This paper describes a method using electrical characteristics of the torch, flame, and work
piece to replace active sensing elements most commonly used for mechanized oxyfuel …

The oxyfuel cutting method is still widely used nowadays, even though it is not a fully
autonomous process. Thisthesis presents a computational model to study ion and electron …
