High-Speed Electrical Arc Spraying Machine

Product Overview

PTJ – 600A High-speed Electric Arc Spraying Machine developed by our company is a high efficiency, low energy consumption and high-tech product.Basing on the electric arc as heat source, melting the metal wire, atomization and cooling with the compressed air, blowing the metal wire into small particles which sprays to the surface of the work piece after heat treatment with high speed, the pipe obtains the ideal coating by the arc spraying machine.

High-speed Electric Arc Spraying Gun can be hand-held or installed on the equipment for spraying. Thus the adaptability is wide

Spraying Principle and Features

Principle: Make two roots of sprayed metal wire as a consumable electrode, the electric arc from the burning end of the wire will melt the equably fed wire, atomize the melted wire into small particles with the compressed air, spray the workpiece to form the coating. Spraying intersect at an angle (usually 30 ° ~ 60 °), two roots of wire sent consecutively, respectively connect cathode and anode. Wire end contact to make the arc starts. Under the function of the power supply, arc keeps stable burning. Behind the arc starting point, melting wires are atomized into to particles by high-speed compressed air, spraying to the pretreated surface to form the coating.
