What is the Distance between two points located on a circle?
On the circle, an arc. Cutting across the circle, a chord.
What is the difference between the center of an arc and the midpoint of an arc?
there is not much difference
Is a circle an arc?
an arc is a segment of a circle. If the arc subtends a full angle of 360 degrees, then the arc is a circle; but this is a special case of an arc.
What is arc gouging?
Arc gouging is a metalworking process that uses a carbon electrode to create an electric arc, melting and removing metal from a workpiece. This technique is often employed for cutting, shaping, or repairing metals, particularly in welding and fabrication applications. The molten metal is ejected from the joint by a high-velocity airflow, allowing for precise control and effective removal of material. It is commonly used in industries such as shipbuilding, construction, and heavy manufacturing.
What is the difference between arc measure and arc length?
Arc measure is the number of radians. Two similar arcs could have the same arc measure. Arc length is particular to the individual arc. One must consider the radius of the arc in question then multiply the arc measure (in radians) times the radius to get the length.
Is plasma cutting cleaner then a torch cutting system?
plasma arc cutting (PAC) systems were much less expensive.Plasma cutting systems can be either plasma cutting tables or handheld torches. A larger, industrial plasma cutting table will obviously cost more
What are some different applications for plasma torches?
There are some different applications for plasma torches (or plasma arc or plasma gun) including plasma cutting, plasma spraying and plasma and waste disposal.
How is an arc created in a plasma system?
An arc in a plasma system is created when a high voltage is applied to ionize the gas in the system. This ionization generates a conductive path through the gas called a plasma column, allowing current to flow across the system. The arc produces intense heat and light, which can be harnessed for various industrial applications like welding, cutting, and surface treatment.
What are ten examples of man-made plasma?
Fluorescent light bulbs Plasma TV displays Plasma cutting machines Plasma arc welding equipment Fusion reactors Magnetohydrodynamic generators Ion thrusters in spacecraft Plasma sterilization technology Plasma torches for material processing Plasma medicine for wound healing
Does water explode in a plasma arc?
Yes, water will explode in a plasma arc. Just spray water into a welding arc and you'll see it happen first hand (not recommended). Water arc explosions are used in metal forming and mining.
What do you use plasma for?
Plasma Cutters are metal working tools. Plasma cutters are generally used for cutting Metals upto an inch in thickness. They use compressed air and electrical current to create an arc similar to welding. The electrical arc heats the metal at a tremendous rate while the compressed air blows it out of the way. These pieces of equipment when used in a computerized setup or by someone with a very steady hand can create very high quality cuts.
How to Use a Plasma Cutter?
A plasma cutter is a device that uses compressed air or an inert gas blown through a high speed nozzle to cut metal. As the inert gas or compressed air is blown out of the nozzle, an electric arc is formed from the nozzle to the surface of the material being cut. Some of the inert gas or compressed air is converted into plasma as it touches the material being cut, and the heat from this plasma is used to cut the metal. There are two types of plasma cutters most commonly used in commercial applications. The HF (high frequency) Contact plasma cutter initiates an arc by using a high frequency, high-voltage spark to ionise the air through the torch head. While the use of this method is quite common, it is not suitable for CNC cutting applications because it requires the torch to be in contact with the material that is being cut. The other method commonly used in commerical applications is the Pilot Arc method. This method uses a high-voltage, low current circuit to create a spark within the torch body. The creation of this spark generates a pocket of plasma gas, or a pilot arc. The pilot arc is able to maintain itself because there is a return electrical path in the torch head. The pilot arc is maintained until the torch comes into contact with the material being cut, at which time the main plasma cutting arc is ignited. Because this method does not require the torch to be in contact with the material it is cutting in order to ignite, this type of plasma cutter is used across all plasma cutter applications. Over the last decade, manufacturers of plasma cutters have continued to roll out new models that feature smaller nozzles and thinner plasma arcs. As these components have become smaller, plasma cutters have been reduced in size to the point where there are now hand-held plasma cutters. This development has made plasma cutters not only easier to handle, but also much more precise. Another benefit of the increasing miniaturization of plasma cutters has been a reduction in their cost. This reduction in cost has now made the purchase of a plasma cutter within the reach of most hobbyists.
What is plasma welding?
Plasma welding is another name for arc welding. It is a process in which electricity super heats air to form a plasma arc. This arc transmits an electrical current to a metal surface and creates heat to melt the metal together thus creating a weld joint.
How does a plasma torch work?
A plasma torch works by generating an electric arc between two electrodes, creating a high-temperature plasma as gas is ionized. This plasma can reach temperatures of several thousand degrees Celsius, making it capable of melting or cutting through various materials. In industrial applications, the gas, often argon or nitrogen, is injected into the torch, where it becomes ionized, allowing for precise control of the heat and energy output. The resulting plasma jet can be directed to perform tasks such as welding, cutting, or surface treatment.
What light is the most dangerous to welders?
The light given off by high voltage arc welding is most harmful but over time, prolonged exposure to the light from shield-gas, oxyacetylene plasma cutting, and torch cutting can cause bleeding behind the macula.
Can plasma exist on earth?
The best example of plasma on earth is lightning. It's natural. The state of matter we call plasma exists at high temperatures. Those temperatures don't usually exist here, but they do for a brief second in a bolt of lightning. Any electric arc creates plasma, and plasma metal cutting equipment can be found is shops around the world. The plasma is so hot that it zips through sheets and plates very quickly. This sustained plasma stream makes short work of cutting applications. We can also find plasma inside operating fluorescent lights. The gas atoms are not superheated, but have high enough energy at the low pressures to become a plasma.
What is a plasma arc?
A very high temperature form of welding and cutting metals, using a jet of plasma.Arc plasma is the temporary state of a gas. The gas gets ionized after passage of electric current through it and it becomes a conductor of electricity. In ionized state atoms break into electrons (−) and cations (+) and the system contains a mixture of ions, electrons and highly excited atoms.A typical value of temperature obtained in a plasma jet torch may be of the order of 28000 °C(50000 °F ) against about 5500 °C (10000 °F) in ordinary electric welding arc.
