Plasma-arc machining (PAM) employs a high-velocity jet of high-temperature gas to melt and displace material in its path. Called PAM, this is a method of cutting metal with a plasma-arc, or tungsten inert-gas-arc, torch.

2024年6月3日 · What is Plasma Arc Machining? Plasma arc machining is a metal removal process in which the metal is removed by focusing a high-velocity jet of high-temperature (11,000°C to 30,000°C) ionized gas on the workpiece.

2023年9月5日 · Plasma Arc machining employs a high-temperature, ionized gas plasma to erode materials. A high-velocity jet of plasma melts and vaporizes the workpiece, producing intricate cuts with minimal heat-affected zones.

Plasma Arc Machining (PAM) is a process that uses a high-velocity jet of ionized gas (plasma) at high temperatures to melt and remove material from a workpiece. It is commonly used for cutting and shaping metals.

The plasma arc machining is used for cutting alloys steels, stainless steel, aluminum, nickel, copper, and cast iron. Working of Plasma Arc Machining. The basic principle is that the arc formed between the electrode and the workpiece is constricted by a fine bore, copper nozzle.

PAM is a method of cutting metal with a plasma-arc, or tungsten inert-gas-arc, torch. The torch produces a high-velocity jet of high-temperature ionized gas (plasma) that cuts by melting and displacing material from the workpiece.

The plasma arc cutting process is illustrated in Fig. 1. The basic principle is that the arc formed between the electrode and the workpiece is constricted by a fine bore, copper nozzle. This increases the temperature and velocity of the plasma emanating from the nozzle.
