What Is Plasma Arc Machining Pam And How It Works

Plasma Arc Machining Basic Terms And Working Pam Best Engineer

Actually all welding arcs are partially ionized plasmas but the one in plasma arc welding is a constricted arc plasma.

Plasma arc machining. Plasma cutting is a process that cuts through electrically conductive materials by means of an accelerated jet of hot plasmatypical materials cut with a plasma torch include steel stainless steel aluminum brass and copper although other conductive metals may be cut as wellplasma cutting is often used in fabrication shops automotive repair and restoration industrial construction and. Introduction the plasma arc machining process was introduced to the industries in 1964 as a method of bringing better control to the arc welding process in lower current ranges. This increases the temperature and velocity of the plasma emanating from the nozzle. Just as oxy fuel torches can be used for either welding or cutting so too can plasma torches which can achieve plasma arc welding or plasma cutting. Now this plasma is targeted towards the workpiece with a high velocity and the machining process starts. Plasma is defined as a gas that has been heated to a sufficiently high temperature to become partially ionized and therefore electrically conductive. That means we get the plasma state that we wanted for plasma arc machining. The torch produces a high velocity jet of high temperature ionized gas plasma that cuts by melting and displacing material from the workpiece. Plasma arc machining pam. The basic principle is that the arc formed between the electrode and the workpiece is constricted by a fine bore copper nozzle. Called pam this is a method of cutting metal with a plasma arc or tungsten inert gas arc torch. The term plasma as employed in physics means ionized particles. Plasma arc machining pam employs a high velocity jet of high temperature gas to melt and displace material in its path. Plasma arc machining pam plasma arc machining is a nontraditional thermal process. Today plasma retains the original advantages.

Plasma arc machining process diagram application advantages and disadvantages. As the gas comes in contact with the plasma there is a collision between the atoms of a gas and electrons of an electric arc and as a result we get an ionised gas. Here you can see the plasma cutter going up and down using the arc voltage. Plasma arc machining pam employs a high velocity jet of high temperature gas to melt and displace material in its path. We taped a video camera to the gantry on our torchmate cnc plasma cutting table for a ride along while it was cutting.
