Electric Wire Arc Spray

The arc spraying process sometimes also called twin wire arc spray involves the melting of two wires (the coating material) as the coating feedstock in an arc. The two wires are electrically charged with opposing polarity and are fed into the arc gun at matched, controlled speeds. When we bring the wires together at the contact point, the opposing charges on the wires create enough heat to continuously melt the tips of the wires. They are then accelerated towards the prepared work surface by means of an atomizing gas which is compressed air.
Arc spraying is a high-performance wire spraying process, but the coating material must be electrically conductive. This arc spray process carried out correctly is called a “cold process” (relative to the substrate material being coated) as the substrate temperature can be kept low during processing avoiding damage, metallurgical changes, and distortion to the substrate material. Additionally, electric arc wire spraying produces spray at higher spray rates than other thermal spray processes, creating some of the fastest coating rates of any coating method.
Anti-corrosion or engineering coatings can be applied by arc spray and changing between the two is quite simple. Arc spray systems are commonly considered to be easy to operate and also to automate. Twin wires are fed via electrically driven motor or air motor.

Electric arc spray coatings are normally denser and stronger than their equivalent combustion spray coatings. Low running costs, high spray rates and efficiency make it a good tool for spraying large areas and high production rates.

About our Wire Arc Spray Equipment

Our constant wire feeding solutions provide you with constant and consistent wire feeding rates for optimum electric arc thermal spraying. Both our arc spray system – DC Drive and Air Drive, are a pull-type system, here the wire is pulled into the arc spray equipment with the help of rollers. In the DC drive gun, the roller rotates with the help of a DC motor, and in the air drive gun, an air motor is provided with ensures wire feeding. We understand that each of your operations offers a unique set of challenges. To help you achieve your challenges, we offer a complete range of Metal Coat wire arc spray systems that are engineered to maximize simplicity, durability, and repeatability regardless of your coating application. Our wire arc spray systems are designed for high performance, ensuring low operating fatigue and significantly reduced maintenance costs.
