Plasma arc cutting ppt.
Plasma can be defined as a superheated electrically ionized gas.
The arc transfers to workpiece once torch is within 1 8 of workpiece.
The plasma arc cutting process is illustrated in fig.
Automation is available with portable trolleys rail.
Plasma cutting ppt 1.
Basically plasma arc machining pam is a metal cutting process where metals are cut with plasma arc tungsten inert gas arc or a torch.
Pac is a thermal material removal process that is primarily used for cutting thick sections of electrically conductive materials.
The cuts are made by a high temperature high velocity gas jet generated by constricting an arc between a tungsten electrode and the component.
Do you know when the pam was introduced.
Our machines are capable to cut materials of up to 150mm 6 inch thickness.
Well pam was introduced in the industries in 1964 as a method that would help in the arc.
Since plasma cutters produce a very hot and very localised cone for cutting they are very useful for cutting and welding sheets in curved or angled shapes.

Pull torch through the cut.
The temperature of the plasma is in excess of 20 000 c and the velocity.
Holding torch firmly to workpiece causes nozzle to stick and makes smooth cutting difficult.
Thermal cutting the plasma has sufficient heat and velocity to blow the molten metal from the cut.
A plasma arc cutting machine cutting the internal sections of a metal part.
For arc cutting plasma can also be defined as an electrically heated gas stream.
Hand torches can usually cut up to 38 mm thick steel sheet stronger computer controlled torches can cut up to 150 mm thick steel sheet.
Ahmad hassan sayed 2 plasma arc cutting.
Plasma arc cutting why was the plasma arc cutting method developed.
This electron movement is what allows the gas to carry the cutting amperage.
The basic principle is that the arc formed between the electrode and the workpiece is constricted by a fine bore copper nozzle.
Plasma cutting is an effective way to cut thin and thick materials.
Pulling is easier than pushing.

Plasma arc cutting 1 plasma arc cutting meng 439 dr.
When cutting thin material reduce amps until you get the best quality cut.
Plasma arc cutting also referred to as plasma fusion cutting or plasma cutting is a fabrication process which employs superheated ionized gas funneled through a plasma torch to heat melt and ultimately cut electrically conductive material into.
The gas stream is heated to such high temperature that it becomes ionized.
This increases the temperature and velocity of the plasma emanating from the nozzle.
We design manufacture air gas plasma cutting machines which cuts through any ferrous and non ferrous material.
