(1) generated by electron beam welding, electron beam welding is a focus on high-speed electron beam bombardment of the surface of the heat welding method. Electron beam welding, electron beam generated by the electron gun and accelerated. Commonly used in electron beam welding include: high-vacuum electron beam welding, low-vacuum electron beam welding and non-vacuum electron beam welding. The first two methods are in the vacuum chamber. Welding Electrode Materials (mainly vacuum time) is longer, the size of the workpiece by the vacuum chamber size limits. Electron beam welding and  Welding Electrode, the main features of the weld penetration, weld width is small, the weld metal of high purity. It can be used in the precision welding of thin materials can be used on very thick (most thick 300mm) component soldering. All other welding methods for fusion welding of metals and alloys using electron beam welding. Mainly used for welding requirements of high-quality products. Can solve the dissimilar metal, easily oxidized metal and the welding of refractory metals. But not suitable for a large number of the amount of product.
(2) laser welding Laser welding is the use of high-power coherent monochromatic sub-streams focused laser beam from the heat source for welding. This welding method is usually a continuous power laser welding and pulsed power laser welding. The advantages of laser welding is not required in a vacuum, the disadvantage is that the penetrating power than the strong electron beam welding. Accurate energy control, laser welding, the welding of precision miniature devices which can be achieved. It can be applied to many metals, in particular, is able to solve some difficult to weld metals and welding of dissimilar metals.

     Vertical circumferential seam automatic welding machine is a compact, inexpensive, easy to operate, can complete a variety of small, round, circular weld universal automatic welding equipment. Its most important feature is applicable to some small parts of the Aluminium Welding Electrode, and the workpiece should not be too long, such as finger length of the workpiece is more suitable for welding.
 The host controller uses the motion controller programmable controller control unit as the core, according to user requirements, modify the procedures and parameters of the control software to regulate the function of the equipment, to achieve a circular, semicircular, segment multi-arc ring welding seam welding, the entire device has a highly intelligent and flexible, a higher grade, higher cost performance and reliability of the controller. The controller has a manual adjustment and automatic welding control; slewing mechanism by DC servo motor drive, stepless welding speed, welding speed displayed by the digital display on the control panel; independent speed control circuit, weld the amount of overlap can set the pre-digital, high-speed reset after torch welding; the controller according to the Nickel Alloy Welding Electrodes requires a variety of control output signals to select and output interface, with a strong anti-interference, high reliability, governor stability, easy operation, high degree of automation characteristics, can be widely applied to the ring weld workpiece welding control
