Plasma arc welding machines, micro-plasma arc welding machine

Plasma arcing principle: the plasma arc using plasma arc welding method as a heat source. The gas produced by the arc heating dissociation at high speed through the water-cooled nozzle is compressed, increasing the energy density and degree of hydrolysis away, forming a plasma arc. Its stability, heat and temperature are higher than the general arc, which has a large penetration force and welding speed. Shielding gas plasma arc gas formation and its surrounding general with argon. According to the material properties of the various parts, but also the use of a mixed gas of argon and hydrogen. Plasma arc welding machine features: 1, micro-plasma arc welding can be welded foil and sheet; arc energy is high, small heat affected zone, welding deformation is small; 2, the arc column rigidity, with keyhole effect, welding speed , high production efficiency, is 3-6 times the normal argon welding; 3, less weld defects, welding materials, high welding quality; 4, excellent reproducibility of the electrode reduction in the nozzle, easy to pollution and burning ; 5, the plasma arc energy density, high temperature arc column, penetration ability; 6, slender arc column, penetration, thin-walled workpieces direct penetration, shorten preparation time, 10 ~ 12mm thickness of steel may not open groove, can be a double-sided molding penetration (ie: side welding), stress deformation. Plasma arc welding and TIG welding, compared with the following characteristics: 1, using a specific process advantages when the plasma arc, not only mainly in the micro-plasma arc welding sheet thickness range of aspects, and involves the use of keyhole techniques. Applications include: surface welding, painting and welding. By using a low adjustable frequency pulse welding current, plasma arc welding arc may be a better way to control the size of the energy can be reliably simultaneous monitoring of the implementation of the various settings through the modern control system. Welding power transistors, such as AUTOTIG series, can be precisely predetermined operation in accordance with the technical specifications. 2, with powder plasma arc welding sheet metal and piping when, with welding speed, small heat input and distortion is small. 3, when the plasma arc welding and other advantages of keyhole technique also clearly manifested plate 6mm thick material aspects of welding. In the application of technology, the powder plasma arc welding with a solid market position.
