Ahmad hassan sayed 2 plasma arc cutting.
Plasma arc cutting why was the plasma arc cutting method developed.
When cutting thin material reduce amps until you get the best quality cut.
The gas stream is heated to such high temperature that it becomes ionized.
The plasma arc cutting process is illustrated in fig.
We supply throughout india export all over the world.
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.
Pac is a thermal material removal process that is primarily used for cutting thick sections of electrically conductive materials.
Plasma can be defined as a superheated electrically ionized gas.
Our machines are capable to cut materials of up to 150mm 6 inch thickness.
The cuts are made by a high temperature high velocity gas jet generated by constricting an arc between a tungsten electrode and the component.
A plasma arc cutting machine cutting the internal sections of a metal part.
The basic principle is that the arc formed between the electrode and the workpiece is constricted by a fine bore copper nozzle.
The temperature of the plasma is in excess of 20 000 c and the velocity.
Do you know when the pam was introduced.
Plasma arc cutting revision 2 0 september 2014 1 2 plasma arc cutting accurate cuts can be made in stainless steel and non ferrous metals such as aluminium by plasma arc cutting.
Pulling is easier than pushing.
Automation is available with portable trolleys rail.
Gaafar prepared by eng.
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.
It is mostly used for the metals that cannot be cut by an oxyacetylene torch.
The arc transfers to workpiece once torch is within 1 8 of workpiece.
For arc cutting plasma can also be defined as an electrically heated gas stream.
This increases the temperature and velocity of the plasma emanating from the nozzle.
Powerpoint ppt presentation free to view.
This electron movement is what allows the gas to carry the cutting amperage.
The ionized gas by definition can then freely exchange electrons between atoms.
Plasma cutting is an effective way to cut thin and thick materials.
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.
We design manufacture air gas plasma cutting machines which cuts through any ferrous and non ferrous material.
Pull torch through the cut.
