At the same time, China's small and medium-power electron beam welding machine has been close to or to catch up with the advanced level of similar foreign products, the price is only about 1/3 of the similar foreign products, there are significant cost performance advantages. Therefore, the electron beam welding equipment applications far exceeds the laser welding equipment. However, in automobile production, high-volume, high efficiency, has become the goal pursued by the car manufacturer, made electron beam welding equipment, and generally do not have a high volume automated production capacity. The car companies need to increase production capacity, often only by increasing the number of electron beam welding equipment and increased manpower to meet the needs of production, comprehensive comparison of down, the economy of the electron beam welding has been damaged. So that  cell phone jammer  has different applicable locations and purposes.
Front of exposition, we can see that the electron beam welding in the ultra-high-power (30kW) and a large penetration depth (50 mm or more) has an irreplaceable position in the welding. In particular: the field of power generation equipment, petrochemical equipment, mining machinery, heavy vehicles, aerospace, nuclear equipment and shipbuilding industry, electron beam welding is still the preferred technical solution. The typical application is the welding of the reactor substrate and the steam turbine rotor shaft bearing parts, penetration of 300mm or more. Compared with the laser welding, electron beam welding, another important feature is not patching material reflected, it can easily be difficult to laser welding, soldering gold, silver, copper, aluminum and other material. The customer can choose the most suitable and appropriate  cell phone jammer .
Such as oxygen-free copper parts in electronic devices, high-current copper bars, copper-tungsten contact and high-powered diesel engine aluminum pistons, etc. These parts are made of electron beam welding of high strength, large penetration depth of welded joints. In order to make the high-power electron beam welding for large parts, and the simultaneous development of high-power electron beam is a large vacuum chamber, a partial vacuum and non vacuum technology. Large vacuum chamber volume reached 800m3, welding diameter 10m, the giant component. Although the cost of a large vacuum chamber, but the excellent welding performance for high-power electron beam welding and high welding speed can make the overall cost (including equipment investment and operating costs) but lower than traditional welding methods. It is as per their requirements towards the power and wavelength of  cell phone jammer .
