What Exactly Is The Weld Wire? When welders place their torch to the source material or material being worked on, they need to use a filler metal that will melt, to create the weld. This filler metal or weld wire has more than one use, it will also protect the welded material from contaminates such as, air. This weld wire is held in one hand while they hold the torch with the other, bringing heat to the source material. The weld wire is very necessary for the welder, because it will help to create the finish that they seek. The welder will use this filler material to build a stronger weld , because when it melts it adds to the strength of the welded joint. There are different types of weld wire, along with different types of welding processes. There are those wires that are covered electrodes, those that are bare wiring, the tubular wire, or the welding fluxing wires. The covered electrodes are those that are used with the arc welding procedure. The arc welding procedure is usually when you see a light or arc while the welder welds his surface. It is the arc welding procedure that uses a weld wire or consumable electrode that has a flux coating on the surface of the weld. This process usually creates a shielding gas, while it is being welded this gas and the wire melting creates slag that protects the weld from contamination. It is the bare electrodes used for weld wire, that are also consumable or disintegrate during its usage. This type of wire is used while performing the (GMAW) Gas metal arc welding process or procedure. This wire electrode will help to create the joint for the welded surface. They are mostly made out of deoxidizing materials like aluminum and also protect the weld surface from contaminates. If the welded source comes in contact with air it will cause a defect to the manufactured product and therefore be of no use to its owner. There are two other type of welding wires most commonly used. There is the tubular electrode wiring and those called the welding flux. The tubular wiring
has a flux core also is one called a consumable. This wiring is oftentimes part of a semi automatic or even a fully automatic welding process or procedure. It is a constant fed consumable wire that can be part of a shielding gas process to protect the source from the atmosphere, just as the others. However, the welding flux is exclusive; it is only used for the submerged arc welding procedure. It too is a continuous-fed flux cored electrode, but it protects the surface while it remains submerged. This procedure can be performed either automatic or semi automatically. This procedure can be done with a hand held gun, used to weld its surface. The weld wires are a vital part of any welding process . There is only the difference in what type of wiring is needed, but will be determined by what type of process and the expected outcome of the weld. It will be decided after the welder has decided how he will weld and what he will weld with. Source: http://everlastgenerators.com/wordpress/welders/what-exactly- is-the-weld-wire
