What is Spray Arc Welding?

Spray arc welding is a welding process in which molten material is transferred in the form of many small droplets, the diameter of which is less than that of the filler wire. The process is popular because it can be used to weld metals with high melting points, such as stainless steel and nickel alloys. Additionally, spray arc welding provides a higher deposition rate than other welding processes, such as gas tungsten arc welding (GTAW).

Spray arc welding is performed using a spray torch, which consists of a power source, an electrode holder, and a water-cooled copper nozzle. The power source provides the energy necessary to melt the filler wire and create the arc. The electrode holder is used to support the electrode and help guide it toward the workpiece. The water-cooled copper nozzle is used to cool the arc and prevent it from becoming too hot.

The spray arc welding process begins by striking an arc between the electrode and the workpiece. Once the arc is established, the operator will begin feeding the filler wire into the arc. As the filler wire melts, it will be deposited onto the workpiece in the form of small droplets. The operator will continue to feed the filler wire into the arc until the desired weld bead is achieved.

What is spray arc steel?

Spray arc steel is a type of steel that can be welded using the spray arc welding process. This type of steel is popular because it can be used to weld metals with high melting points, such as stainless steel and nickel alloys.
