Do you know when the pam was introduced.

Plasma arc cutting ppt.

A plasma arc cutting machine cutting the internal sections of a metal part. Plasma can be defined as a superheated electrically ionized gas. 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. When cutting thin material reduce amps until you get the best quality cut.

The plasma arc cutting process is illustrated in fig. 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. 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. Plasma cutting is an effective way to cut thin and thick materials.

The ionized gas by definition can then freely exchange electrons between atoms. Ahmad hassan sayed 2 plasma arc cutting. 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.

We supply throughout india export all over the world. Pulling is easier than pushing. The arc transfers to workpiece once torch is within 1 8 of workpiece. Automation is available with portable trolleys rail.

Basically plasma arc machining pam is a metal cutting process where metals are cut with plasma arc tungsten inert gas arc or a torch. It is mostly used for the metals that cannot be cut by an oxyacetylene torch. 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. Gaafar prepared by eng.

This increases the temperature and velocity of the plasma emanating from the nozzle. Well pam was introduced in the industries in 1964 as a method that would help in the arc. Our machines are capable to cut materials of up to 150mm 6 inch thickness. Holding torch firmly to workpiece causes nozzle to stick and makes smooth cutting difficult.

The basic principle is that the arc formed between the electrode and the workpiece is constricted by a fine bore copper nozzle. Plasma cutting ppt 1. The gas stream is heated to such high temperature that it becomes ionized. Thermal cutting the plasma has sufficient heat and velocity to blow the molten metal from the cut.

We design manufacture air gas plasma cutting machines which cuts through any ferrous and non ferrous material. This electron movement is what allows the gas to carry the cutting amperage. Plasma arc cutting why was the plasma arc cutting method developed. Powerpoint ppt presentation free to view.
