A non traditional process of metal removal that involves focusing a high-velocity jet of high-temperature (11,000°C to 30,000°C) ionized gas on a workpiece.
What is Plasma ?
When the temperature is raised to nearly 3000 °C, electrons in gas atoms are displaced, and the atoms are ionized, this ionized gas is known as plasma.
Working Principle of Plasma Arc Machining
It based on the principle of using high temperature plasma jet to remove the material by melting the contents of the workpiece.
