Twin Arc Spray Gun is a process that uses an electric arc to melt the wires. The molten metal is then atomized with compressed air to create a spray stream that applies the coating onto the surface being coated.
Product Details:
Air Pressure | 50-70 PSI |
Air Inlet size | 1/4" |
Nozzle Size | 1.3-2.5 mm |
Air consumption | 8-9 CFM |
The twin wire arc spray process (TWA) utilizes metal in wire form materials. Heating and melting of the wire material occur when two electrically opposed charged wires, comprising the spray material, are fed together in such a manner that a controlled arc occurs at their intersection. The molten metal is atomized and sprayed onto the prepared workpiece by jets of compressed air or gas. The molten metal was reduced by jets of compressed gas. a device was built utilizing two aluminium wires, insulated from each other, made to advance and intersect at some point. Generally, the wires were given a difference of electrical potential of about 89 V that caused the wires to melt, and in the presence of a gas stream, the coating was produced. Two guides direct the wires to an arcing point. After this point, a sand blasting nozzle directs a stream of high-pressure air onto the arcing point where it atomizes the molten metal and sprays it to the workpiece. Power of about 450 A can spray over 50 kg/hr (110 lb/hr). Electric arc spray systems are offered that wire by either air or an electrical motor. The system pushes the wire to the gun while others pull the wire into the arc. Control units include voltmeter and ampere meters and air regulators. A twin arc spray gun price does not require the use of oxygen and/or combustible gas. It has determined the ability to process metals at high spray rates. This concept experimented with electrical heating for spraying. In that case, One pole was a graphite crucible that is loaded with the consumable, the other one is a carbon rod. An arc was struck between the crucible and the rod causing the metallic consumable to melt the metal and flow through an orifice.
Twin Arc Spraying is an interaction where two wires are accused of anode and cathode. At the point when these charged metalizing wires are contacted then it creates a flash. Shimmered prompted produces heat that will keep an eye on emergency the wire. The air from the air blower pushes wire and liquid metal to the outside of a workpiece. Dry compacted air is utilized for atomizing and pushing the liquid metal. A pressure blasting machine impacting 90-100 psi is utilized. Practically any metal that can be brought into a wire can be sprayed. Coming up next are metals that are arc sprayed: Ferrous and Non-Ferrous, aluminium, zinc, titanium, metal, bronze, copper, molybdenum, Inconel, Monel, nickel, stainless steel, carbon steel, tin. The control unit is utilized for controlling the packed air and dc supply to the wires.
The working guideline of the Twin Wire Arc Spray Gun price is basic for comprehension. It chips away at the standard of Electric arc spraying is a warm spraying measure that utilizes an electric arc spray gun between two consumable cathodes of the surfacing materials as the warmth source. A compacted gas atomizes and moves the liquid material to the workpiece.
