Kipinäsulatustekniikat, also known as spark melting techniques, refer to a group of processes that utilize electrical sparks to melt and fuse materials. These techniques are generally characterized by localized and rapid heating, allowing for precise control over the melting process.

One common application of spark melting is in the repair and modification of metal components. By directing a stream of high-energy sparks onto a specific area, small amounts of material can be melted and added or reshaped. This can be useful for tasks such as filling in small cracks, building up worn surfaces, or creating intricate designs. The localized heating minimizes the risk of heat distortion to the surrounding material, which is a significant advantage over traditional welding methods in some applications.

Another area where spark melting finds use is in the production of specialized materials. For instance, in powder metallurgy, spark erosion can be employed to create fine, spherical metal powders by melting and atomizing small droplets of material. These powders can then be used in additive manufacturing or other advanced material processing techniques. The ability to control particle size and morphology through spark melting is a key benefit.

The underlying principle involves the rapid discharge of electrical energy through a gap, creating a plasma channel that generates intense heat. This heat is then transferred to the workpiece, causing localized melting. The specific parameters, such as spark energy, frequency, and electrode material, can be adjusted to suit the material being processed and the desired outcome.
