In welding applications, the term "wire core" or "insulated wire" refers to the electrode wire used in certain welding processes such as MIG (Metal Inert Gas) or TIG (Tungsten Inert Gas) welding. Here is a brief explanation of the term wire core or insulated wire in welding:

Function: in welding, the wire core or insulated wire acts as a consumable electrode that conducts the electric current to create the welding arc. It is designed to melt and provide the filler metal needed to produce the weld.

Structure: The wire core for welding usually consists of a solid metal wire as the conductive core. The core wire is often made of materials such as carbon steel, stainless steel, aluminum or other alloys, depending on the welding process and the type of metal being welded. This core wire is surrounded by an insulating layer, which can be a copper coating or an external plastic coating, depending on the type of wire.

Electrical conductivity: The conductive core of the wire enables the efficient transfer of electrical current from the welding power source to the arc. The electric current flows through the wire and creates a high-temperature arc that melts the wire and the base material to form the weld.

Shielding gas: In certain welding processes, such as MIG welding, the wire core is also responsible for supplying the shielding gas to protect the weld pool and the electrode from atmospheric contamination. The shielding gas flows through the welding torch and exits through the nozzle. It envelops the wire and the welding area, prevents oxidation and ensures a clean weld seam.

Filler metal: The wire core serves as a source of filler metal during welding. As the wire melts, it provides the molten metal that is introduced into the weld to fill any voids or form the desired weld bead. The composition of the wire core determines the properties and characteristics of the weld metal, such as strength, corrosion resistance or conductivity.

Size and types: Wire cores for welding come in different sizes or diameters, which are selected according to the specific welding application and the desired weld thickness. They are available in different versions, e.g. as solid wire or cored wire, each offering different advantages and suitability for specific welding processes or materials.
