Plasma cutting is a process by which a compressed gas isblown onto a metal surface. An electric arc is created which raises the gas toextremely high temperature hot enough to cut through metal very quickly. Theforce of the gas is able to blow away any molten slag that may have collectedon the cut surface, leaving a very clean edge. Since the compressed gas can befocused to a fine point, highly accurate cutting to create intricate shapes anddesigns can be done. The origins of plasma cutting can be traced back to the daysof World War II and the need to increase the speed and quality of aircraftproduction. Plasma welding was developed to cut the time taken for thefabrication of body parts and had the advantage of producing stronger jointsthan conventional welding techniques of the time. In the 1960s this technology was improved by new method ofincreasing the gas temperature and more finely focusing the stream of gas toallow the plasma stream to be used to cut through metal like a knife, withgreat accuracy. For industrial applications, large plasma cutters are operatedby computers to produce high precision cutting in large volume. Artists use hand held plasma cutter for their work. Thesesmall yet powerful units can be wielded like a knife and can be used to cutthrough metal to produce intricate shapes and designs. Think of a sheet ofmetal as a blank canvas and the plasma cutter as the brush. Either by free handor by using a stencil, the artist cuts through the sheet metal to create thedesign or art work he wants. Once the cutting is done, the artist can use theequipment to carve out delicate features or create etchings on the surface ofhis creation. Bending some of the surfaces can be done to add a threedimensional effect. Since plasma cut sheet metal is thin and delicate by nature,it cannot be used under extreme conditions like large sculptures or as loadbearing works of art. The main application is to use this technology to createmirror and picture frames, table top ornaments and other such decorative items.Unlike large pieces of metal art, those created by plasma cutting need to beprotected from the elements and are meant for indoor use. When buying plasma metal art, it needs to be kept in mindthat the cost of the material used and the production process makes up only aminor part of the total cost. Except in the case of certain very expensivealloys, sheet metal in not very costly and the cost of using a small hand heldplasma cutter is relatively cheap. The value of plasma art likes in the qualityof the art the concept and design, the quality of the production and thefineness of the detail incorporated into the work. A search of the internet will reveal the vastvariety of plasma metal art available from the reasonably priced to theprohibitively expensive. Just about any kind of decorative metal art can bemade by the plasma cutting process and if a buyer has something special inmind, finding an artist who will create what the client wants is not a problem.
