Plasma Arc Cutting Ppt

We design manufacture air gas plasma cutting machines which cuts through any ferrous and non ferrous material.

Plasma arc cutting ppt.

The gas stream is heated to such high temperature that it becomes ionized. Powerpoint ppt presentation free to view. Our machines are capable to cut materials of up to 150mm 6 inch thickness. The plasma arc cutting process is illustrated in fig.

Holding torch firmly to workpiece causes nozzle to stick and makes smooth cutting difficult. This electron movement is what allows the gas to carry the cutting amperage. Gaafar prepared by eng. The ionized gas by definition can then freely exchange electrons between atoms.

The cuts are made by a high temperature high velocity gas jet generated by constricting an arc between a tungsten electrode and the component. 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. When cutting thin material reduce amps until you get the best quality cut. The basic principle is that the arc formed between the electrode and the workpiece is constricted by a fine bore copper nozzle.

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. A plasma arc cutting machine cutting the internal sections of a metal part. The temperature of the plasma is in excess of 20 000 c and the velocity.

Ahmad hassan sayed 2 plasma arc cutting. Plasma cutting is an effective way to cut thin and thick materials. Plasma arc cutting 1 plasma arc cutting meng 439 dr. We supply throughout india export all over the world.

Plasma cutting ppt 1. This increases the temperature and velocity of the plasma emanating from the nozzle. Basically plasma arc machining pam is a metal cutting process where metals are cut with plasma arc tungsten inert gas arc or a torch. Well pam was introduced in the industries in 1964 as a method that would help in the arc.

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. Pulling is easier than pushing. The arc transfers to workpiece once torch is within 1 8 of workpiece. It is mostly used for the metals that cannot be cut by an oxyacetylene torch.

Plasma can be defined as a superheated electrically ionized gas. For arc cutting plasma can also be defined as an electrically heated gas stream. Thermal cutting the plasma has sufficient heat and velocity to blow the molten metal from the cut. Automation is available with portable trolleys rail.

Pull torch through the cut.
