New thermal processing technology called Ring of Fire. It has the capacity to process all AISC structural shapes, including beams, columns, angle iron, channel iron, HSS square and rectangular tubes, and plate and flat stock. The compact machine uses plasma cutting and precise positioning to process all four sides of structural tube. It provides AISC-approved bolt hole generation and also serves as a cutoff device for running multiple sections. The machine also performs surface beveling, weld prep, standard coping, and flange thinning. It makes interior web/flange cuts and produces legible electronic marking.A self-contained dust collection and filtration system is standard.Plasma cutters have also been used in CNC (computer numerically controlled) machinery. Manufacturers build CNC cutting tables, some with the cutter built in to the table. The idea behind CNC tables is to allow a computer to control the torch head making clean sharp cuts. Modern CNC plasma equipment is capable of multi-axis cutting of thick material, allowing opportunities for complex welding seams on CNC welding equipment that is not possible otherwise.
For thinner material cutting, plasma cutting is being progressively replaced by laser cutting, due mainly to the laser cutter's superior hole-cutting abilities. A specialized use of CNC Plasma Cutters has been in the HVAC industry. Software will process information on ductwork and create flat patterns to be cut on the cutting table by the plasma torch. This technology has enormously increased productivity within the industry since its introduction in the early 1980s. In recent years there has been even more development in the area of CNC Plasma Cutting Machinery. Traditionally the machines' cutting tables was horizontal but now due to further research and development Vertical CNC Plasma Cutting Machines are available. This advancement provides a machine with a small footprint, increased flexibility, optimum safety, faster operation, energy efficiency, ergonomic and more environmentally friendly.In the past decade plasma torch manufacturers have engineered new models with a smaller nozzle and a thinner plasma arc. This allows near-laser quality on plasma cut edges. Several manufacturers have combined precision CNC control with these torches to allow fabricators to produce parts that require little or no finishing.Plasma torches were once quite expensive. For this reason they were usually only found in professional welding shops and very well-stocked private garages and shops. However, modern plasma torches are becoming cheaper, and now are within the price range of many hobbyists. Older units may be very heavy, but still portable, while some newer ones with inverter technology weigh only a little, yet equal or exceed the capacities of older ones.
This was largely thanks to private industry's tremendous innovations in the field of mass production. One area of innovation rose out of the need to cut and join aircraft parts more efficiently. Many factories working on military aircraft adopted a new method of welding that involved the use of an inert gas fed through an electric arc. The breakthrough discovery was that charging the gas with an electric current formed a barrier around the weld, which protected it from oxidation. This new method made for much cleaner lines at the joints and much sturdier construction. In the early 1960s, engineers made a new discovery. They figured out that they could boost temperatures by speeding up the flow of gas and shrinking the release hole. The new system could reach higher temperatures than any other commercial welder. In fact, at these high temperatures, the tool no longer acted as a welder. Instead, it worked like a saw, cutting through tough metals like a hot knife through butter. This introduction of the plasma arc revolutionized the speed, accuracy and types of cuts manufacturers could make in all types of metals. In the next section, we'll examine the science behind this system. The unique Plasma and Corona technologies improve wettability of plastic materials with low surface energy, i.e. polyolefin materials, PE, PP and many others, by raising its surface energy and improve adhesive characteristics by creating multiple bonding sites.The most advanced and successful methods of surface treatment are based on high voltage discharge in air at atmospheric pressure (Corona/Plasma), or under vacuum (Plasma). Both Corona and Plasma is used to raise surface tension on plastics; Plasma Treatment is also used as a cleaning process to remove organic contamination from plastic, rubber and metal surfaces.Tantec’s equipment is available as standard units, or customized machines to suit numerous industrial applications in the automotive, aerospace, medical device, packaging and electronics industry.
