The aluminum spray gun is utilized for the coating process with aluminum wire on the surface of the substrate to avoid the risk of rust also oxidation.
Aluminum wire is sprayed in an aluminum spray gun and sprayed across the surface of the component after melting it. In this process to melt, the aluminum wire oxygen & acetylene or sometimes LPG gas is applied with compressed air. Sometimes Oxygen & acetylene melt the aluminum wire and compressed air is applied to atomize the molten metal or semi-molten metal on the surface of the substrate. In aluminum spray gun rollers are used to push also pull the wire in forward and backward direction.
The aluminum spray gun is also utilized as an arc to melt the feeding material. An electric arc is produced between cathode & anode to melt or semi melts the coating material.
Aluminum coating extends the life of the substrate. The aluminum spray gun coating process provides high corrosion resistance. Aluminum spray guns needed minimal maintenance.
Coating with the aluminum spray gun is done after the surface preparation process. The surface preparation process of the substrate is done with the sandblasting machine. The Aluminium coating is done to prevent the surface from rust, also oxidation.
An aluminum spray gun gas flow meter is applied to check the flow of gases. In gas flow meter flow of oxygen & acetylene to be set according to the requirement. More flow of gases (oxygen + LPG/ Acetylene + Compressed Air) can damage spray guns including coating material. And if the flow of gas more than the equal coating is hard to do on the surface of the substrate.
