Plasma flow control during welding applications keyhole effect welding, the control module can achieve plasma welding arc switching machine plasma flow proportional control when receiving arc plasma gas as the current decreases and the decrease in the final at the Crater no perforation to ensure the weld crater when. Features: 1, the arc energy is high, small heat affected zone, welding deformation is small; 2, the advantages of plasma welding arc slender columns, etc., penetration, thin workpieces without beveling, shorten time to prepare double-sided welding side molding 3, fast plasma welding, TIG welding is 3-6 times the normal; (4) the arc column rigidity, due to keyhole effect, to achieve a one-side welding molding; 5, less weld defects, welding material , high welding quality; 6, excellent reproducibility of the electrode reduction in the nozzle, easy to pollution and burning.
