Wire Flame Spray Gun is the type of process which uses an oxy-fuel to melt the wires. After melting the heated metal is then atomized with compressed air to produce a spray stream that applies the coating on the surface implying sprayed. Wire flame spray (coating) is applied to spray both ferrous & nonferrous material. Important applications are restoring worn-out components, anti-corrosion coating, and conductivity.

Wire Flame Spray Gun Working
The wire is fed into the front torch of flame spray through an air-driven turbine. Fuel gas like acetylene, LPG, Propane & oxygen is properly and securely mixed in the siphon plug head assembly which gives a combustible heat source.
Generally, proper for all metals and metal alloys in wire form are used for spray coating i.e. Nickel Alloy, Zinc, Stainless Steel, Copper, Bronze, Steel, Molybdenum, Aluminum Brass, etc. Standard Wire used for the flame spray gun.
The molten spray deposit and solidifies on the element surface to form a dense, strongly adherent coating is proper for Corrosion Protection.
Applications of Wire Flame Spray Gun
- Reclaiming parts for roller and shaft.
- Wear coatings, Molybdenum
- Non-ferrous: Copper, Bronze coating
- Fine coatings with low heat input
Features of Wire Flame Spray Gun
- Suitable for wires, steels, copper, and bronzes plus anti-corrosion materials.
- Larger areas to be sprayed efficiently.
- Freestanding wall control panel with Safety shut-off valve.
- Use such fuel only i.e. Oxygen, Nitrogen.
- Conductive coating applications.
- Resistance to wear, abrasion, and erosion.
Flame Spray Gun Process
The superiority of the wire flame spray process is that the coatings are available for almost instant use with no drying times and no risk of damaging the element. Flame spray systems can commonly manually perform, semi-automated, or fully automate the method if required.
Wire spray gun system comprises the following :
- Wire flame spray gun
- Gas Flow Meter
- Gas control unit
- Air control unit
- Wire reel stand
- Hose unit
Flame spraying is most commonly used to apply abrasion-resistant coatings or nickel/chrome self-fluxing alloys, which are then heat-treated to metallurgically attach them to the substrate (Fused coatings).
In compressors, abrasion-resistant coatings are employed for machine element clearance.
Fused coatings are widely utilized in high-wear sectors like mining and the steel industry to protect roll, piston, and other equipment from wearing out in harsh environments.
A Flame Spray cannon creates a flame with oxygen and fuel gasses into which powder is shot. Many of the coatings sprayed using this method are then heat-treated at roughly 1000 degrees Fahrenheit to ‘fuse’ them to the substrate surface.
Wires to be Used
- Zinc Wires- Zinc Coated Wires are available in a variety of sizes with constant mechanical qualities, uniform zinc coating, and a bright surface finish. These are mild carbon or high carbon steel wires that have been zinc-coated to improve the properties of the base wire.
- Mild Steel Wires- Galvanized in a hot dip process Mild steel wires with diameters ranging from 0.9 to 4.0 mm. According to IS: 280 -2006, zinc coatings range from 30 gm/sq. meter to 290 gm/sq. meter. As B.S. or as per the buyer’s specifications. Hot Dip Galvanizing is used to apply the zinc coating.
- Aluminum Wires- These are usually composed of a coated aluminum alloy that may be used with either aluminum wire or copper wire. Because long-term installations have shown its reliability, larger stranded aluminum wiring with suitable terminations is typically deemed safe.
- Copper Wires- To provide continuous welding, this series of solid steel wires is covered with thin and homogenous copper. These wires can be used to place CO2 shield gas on unalloyed and structural steel.
