Introduction
Welding is found in just about every industry and is one of the biggest fabrication tools. Welding wire is another tool used in the shop. Welding wire is material in wire form used to carry the current for welding. It’s available in various types so as to suit the variety of applications it’s intended for. This blog will endeavor to highlight the various types of welding wire and their specific applications so as to invoke the understanding of how, in short, the correct selection of welding wire can prove crucial for any given welding project.

What is Welding Wire?
In the welding process welding wire itself is the piece of the puzzle that forms the molten to form a join between the work pieces. The many variables for selecting the correct welding wire selection may depend on the kind of metal being welded, the process being used and also the requirement for the project at hand.
The Types of Welding Wire
Solid Wire
The most well-used type of welding wire which is otherwise known as GMAW (Gas Metal Arc Welding) wire. For all intents and purposes, it is a solid metal wire which is supplied to the welding work regime. Suitable for welding metal such as: –
- Mild Steel
- Stainless Steel
- Aluminium
This type of wire has many uses and can be used for all types of welding from hand welding through to wire up the semi – automatic and fully automated welding. This wire is used across many different industries in-fact you will be hard pushed not to find this mentioned in your own industry.
Flux-Cored Wire
The name comes from the compound in the wire which when heated causes a shielding gas or flux as it’s technically known. This process is almost springing up an external gas tide. The results hoped to achieve better cold, more control, lower overall costs of welding, and good welding can be obtained in low welding applications. It is perfectly suited for outdoor welding and welding that is being performed on fine days with a small mountain gust that will penetrate the shielding gas – therefore using flux to counteract this weathering effect. Flux-cored welding wire as suggested has a wire feed rate, that is to control the filling of its welding rod.
Metal Cored Wire
Which is a sort of combination of the previous two. It includes a core of metal powder but is surrounded by a metal sheath just like solid wire. A specialist kind of wire used by folks who are welding for a trade or for example site work. I can obtain quite high deposition rates, so therefore is used a lot in the Car industry, and in construction but comes into general fabrication as well. Metal is much like solid wire in mystery because the benefits of both are created in this wire i.e. this is an all positional wire it combines the features of flux cored wire (absence of cleaning) and solid wire (high deposition rates).
Submerged Arc Welding-Wire
– Submerged arc welding or saw-wire is a type of welding wire. The process is quite specific, in that the flux of granulised is run to obvert but the arc itself is not – because the arc is created by the welding wire transfers. For that composite wire is always very large as this is where wire can be drawn to be of a rural small diameter. Mining or other heavy welding such as heavy construction to name but a few. This is a position of wire to be used as the length of arc welding creates a strength behind it (the arc welding passes the plate in the pressure vessel tank by creating the ability and bridge or a bridge work, the length of the arc is always guaranteed – this will give you a very shallow penetration but has a very high tail out rate.
