An arc spray gun manufacturer is a coating process during which where two consumable metal wires are fed independently into the spray gun. Certain wires are then charged and an arc is produced between them. the heat of this arc melts the incoming wire, which is then entrained in an air jet of the gun.

In this method, the two electric conductive consumable wires ( twin wire arc spray gun ) are continuously fed into the arc spray gun. The gun geometry is designed such the wire tips are separated by a distance of a few tenths of a millimeter from each other. an electrical voltage of about 40 V, applied on the two wires, causes an arc within the gap between the wire tips. The arc heats the tips of the wires and makes a thin layer of molten material. A stream of atomizing gas, as shown within the figure, strips the molten layer of the wire tips and propels it towards the substrate.
The detached molten droplets will not only stimulate but also undergo further atomization and produce smaller droplets. The molten droplets are then collected on the substrate one over another, where they solidify and form a coating layer. The material that is utilized in this process is introduced into the process within the sort of two electrically-conductive consumable wires. The wires commonly used in industry are usually made from electrically-conductive materials, like Aluminum wire, stainless steel, zinc wire, and Copper, intermetallic compound coatings, and metal-ceramic composite coatings were prepared by using pre-alloyed wires and cored wires, during which non-conductive materials are used because of the core of a conductive wire.
We are the leading arc spray gun manufacturer and we also supply and export arc spray systems, zinc spray guns, flame spray gun, and thermal spray gun. Thermal Spray Gun should be used after creating a rough surface so that automized spray metal makes a good grip on the metal, then the metal life is increased by this process.
