Wire Flame SprayGunis that the type of method in which uses an oxy-fuel flame to melt the wires. To create a spray of a stream that applies to coat on the surface to spray on an entity.A Spray gun is used for spray both ferrous & nonferrous material. Important applications are restoring worn-out components, conductivity and anti-corrosion coating.

Wire Flame Gun Working
Flame Spray Gunutilized for flame spray. The wire is fed into the front torch of theflame spray gunthrough an air-driven turbine. Then the wire is melted down by flame combustion of fuel and oxygen. Through compressed air molten metal is pressurized outwards.
Wire Flame Spray Gun Advantage:
The Wire flame Spraying process has many advantages such as
- Low Cost,
- Easy to operate,
- Simple in design, and dust and fumes levels are lower.
- It is widely used for Corrosion protection of structures and machine parts (e.g. bridges, offshore platforms, LPG bottles).
- For corrosion protection of structures and machine components and reclamation wore shafts flame spray process is mainly used.
- It is used where a cost-effective thermal spray coating is desired and lower quality can be tolerated.
Flame Spray Gun Process
的苏periority of the flame spray process is the coatings are available for almost instant use with no drying time and no risk of damaging the element.Flame spraygunsystems can generally manually performed, semi-automate or fully-automate the method if required. Copper, Zinc, Aluminium Brass, Nickel, Steel,Stainless Steel, etc. Metals and metal alloys in the form of wire are used for spraying in thethermal spray coating. The molten spray deposit & solidifies on the element surface to form a dense. Strongly adherent coating is proper for Corrosion Protection.
Types of wire flame spray gun
What is different b/w wire and powder flame spray gun ?
In thewire flame sprayprocess, the wire spray material is melted in a gaseous oxygen-fuelflame. The wire is filled continuously into the fuel gas-oxygen flame, where it is melted and atomized by the addition of compressed air that also directs the melted onto the substrate. Combustion wire flame spray is a common option for machine element repair and corrosion coatings such as bridge piers and Yankee dryer Rolls.
Thepowder flame sprayprocess utilizes a similar technique of wire Flame spray process, except that the wire feedstock is replaced withpowder. The process is fundamentally the spraying of molten material onto a surface to provide a coating. The material in powder form is melted in aflame(oxy-acetylene or hydrogen most common) to form a fine spray. When the spray attaches the substrate, the fine molten droplets rapidly solidify forming a coating.
What is Flame Spray Gun and how to work?
Flame spray gunuses combustible gas as a heat source to melt the coating material.Rod,wire, orpowderspraymaterial can be used inFlame spray guns.flame spray gunscan be modified to use different sequences of gases to balance operating costs andcoatingproperties. Acetylene, propane, methyl-acetylene-propadiene (MAPP) gas, and hydrogen, along withoxygen, are generally utilizedflame spraygases. commonly, changing thenozzleand/or air cap is all that is needed to adapt the gun to various alloys, wire sizes, or gases.
