  • Plasma cutting - Function, advantages and disadvantages

    Jun 25, 2019 · Plasma cutting is an effective way to cut thin and thick materials. 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. 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.

  • Plasma Arc Machining (PAM) - Mans

    Plasma Arc Machining (PAM) Plasma arc machining is a nontraditional thermal process. Plasma is defined as a gas that has been heated to a sufficiently high temperature to become partially ionized and therefore electrically conductive. The term plasma, as employed in physics, means ionized particles.

  • Plasma Arc Machining: A Review

    3. Dual-flow Plasma Arc Cutting: Dual-flow Plasma Arc Cutting is slight modification of conventional PAC. It incorporates most of the features of conventional PAC but adds a secondary shielding gas around the nozzle. The cutting gas is usually nitrogen the shielding gas is selected according to metal to be cut. Cutting speeds are slightly better

  • Advantages and Disadvantages of Plasma Arc Welding,Cutting

    Advantages of Plasma Arc Welding. Following are the advantages of Plasma Arc Welding: Torch design allows better control of arc. This method provides more freedom to observe and control the weld. The higher heat concentration and plasma jet allows faster travel speeds. The high temperature and high heat concentration of plasma allow keyhole effect.

  • AIR PLASMA CUTTING MACHINES

    • The cutting process is carried out by using shop floor compressed air. Thus the process becomes cheap and flexible. The unique pilot arc system ensures perfect arc start on painted and rusted surface. • An electro-pneumatic protection cuts the arc in case of insufficient air supply adding to the safety of the machine and torch.

    Apr 08, 2021 · What is the advantage of Plasma Arc Welding? The principal advantage of this process is that it is almost equally effective on any metal, regardless of its hardness or refractory nature.

  • Understanding and Suppression of Magnetic Arc Blow in ...

    Plasma arc cutting is widely used in metal cutting because of its advantage of high speed cutting. However, when a magnetized steel plank is cut, the electromagnetic force induced by magnetic flux leakage in the cutting edge deflects the arc plasma jet. Deflected plasma jet roughens the cutting surface and damages the nozzle as the arc cutting ...
