Plasma cutting ppt 1.
Plasma arc cutting ppt.
The gas stream is heated to such high temperature that it becomes ionized.
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.
For arc cutting plasma can also be defined as an electrically heated gas stream.
Our machines are capable to cut materials of up to 150mm 6 inch thickness.
We design manufacture air gas plasma cutting machines which cuts through any ferrous and non ferrous material.
Holding torch firmly to workpiece causes nozzle to stick and makes smooth cutting difficult.
When cutting thin material reduce amps until you get the best quality cut.
Plasma cutting is an effective way to cut thin and thick materials.
A plasma arc cutting machine cutting the internal sections of a metal part.
Pull torch through the cut.
Powerpoint ppt presentation free to view.
The plasma arc cutting process is illustrated in fig.
Ahmad hassan sayed 2 plasma arc cutting.
Thermal cutting the plasma has sufficient heat and velocity to blow the molten metal from the cut.
Pulling is easier than pushing.
It is mostly used for the metals that cannot be cut by an oxyacetylene torch.
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.
Do you know when the pam was introduced.
Pac is a thermal material removal process that is primarily used for cutting thick sections of electrically conductive materials.
Plasma arc cutting 1 plasma arc cutting meng 439 dr.
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.
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.
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.
Automation is available with portable trolleys rail.
Plasma can be defined as a superheated electrically ionized gas.
This increases the temperature and velocity of the plasma emanating from the nozzle.
Plasma arc cutting why was the plasma arc cutting method developed.
Well pam was introduced in the industries in 1964 as a method that would help in the arc.
The arc transfers to workpiece once torch is within 1 8 of workpiece.
Gaafar prepared by eng.
We supply throughout india export all over the world.
The ionized gas by definition can then freely exchange electrons between atoms.
