Issues in the Field of Engineering - Essay Example The carbon dioxide laser cutting and wielding machines applies the use of energy state transition which occurs between the rotational states and the vibration states of the carbon dioxide molecule to help in the emission of light long infrared. This wave1lengths often occurs at about 10 Â µm. The carbon dioxide lasers helps in the maintenance of continuous and high levels of the power applied, making them suitable in cutting and marking applications. They are often applied in the cutting of steel and super alloys at various power levels ranging from 1 to 5 kW. The lasers are also applied in the laser eye and in the correction of the laser vision. (Krar 51) Some of the specifications for the cutting and the laser wielding machines which includes the transverse speed, power, Y-axis travel, X-axis travel and the Z-axis travel. Usually there are three different types of carbon dioxide lasers: transverse gas flow, axial gas flow and the sealed tube. For the various sealed tube lasers, the power output is 40 to 80 watts (W) per meter of the each of the tube length. The lasers are usually pumped by flash lambs, near IR laser diodes and also the gas discharge lambs. A number of the specialty laser cutting and welding laser cutting machines are applicable in the cutting of pipes tubes, films, adhesives and composite materials. The laser cutting and welding machines helped in the cutting of machines are specifically designed in the cutting of rubber, plastic, stone, marble, metal, foam, granite and the composite material. Some of the laser cutting and welding machines include integral interface and computer interface. Other systems include moto rized heads, robotic arms, guidance modules, pallets, gantry tables, monitoring systems, cabinets, sensors and laser optics. Various laser cutting and welding machine helps in the designing of applications with highest demand on the cutting speed. The fields of application
