Cored wire welder

The so-called flux-cored wire welder to be presented here and in the course of the text is also quite well known and familiar to specialists and welding experts under the common product designation as a soul wire welder.

Compared to completely free manual welding, in which the welder only has the actual welding torch at his disposal, the use and application of such a flux-cored wire welder or also a wire welding machine, however, already represents an application from the context of so-called partially mechanized welding, which not only brings with it a significant simplification for the craftsman in terms of handling the work sequences and welding processes but which ultimately can also always guarantee a far more significant and exact accuracy of the weld seam produced and generated with such an aggregate.

Thus, the use and application of the flux-cored wire welder in the actual welding process mean further development of this important joining process for metallic raw materials, parts, and components.

The load that components joined with the flux-cored wire welder are then allowed to experience in daily practice and can withstand accordingly, can now also be designed accordingly high here.

The core and the main component of the so-called flux-cored wire welding machine are always, as can be read quite clearly from the product designation, the flux-cored wire or also soul wire.

In practice, this is regularly a filled tubular wire that can be mechanically advanced through the device during the welding process with the help of a motor integrated into the device and then welded by the worker at the same time.

What is a flux-cored wire welder?

A flux-cored wire welder, which is to be introduced and presented here as an example, is work equipment, tool, and instrument, which can be regularly applied and used in practice for so-called partially mechanized arc welding.

The filled tubular wire, or soul wire, is fed and moved towards the so-called weld pool by means of an electric feed motor, optionally also continuously at different speed levels, which ultimately always depends on the progress of the respective welding process.

This makes the actual arc welding process easier and faster for the operator since he no longer has to feed and refeed the filler wire by hand, which is comparatively cumbersome.

The weld seam that can be achieved and generally generated with the flux-cored wire welder is therefore characterized by great uniformity and correctness in this partially mechanized form of modern arc welding.

The shape of such a weld seam generated with a flux-cored wire welder is already reminiscent of those types of weld seams that can generally be produced and drawn with an automatic welding machine today.

The heart of such a modern flux-cored wire welder is, as has already been described and explained at the beginning, the so-called flux-cored wire or soul wire. This was originally once simple flat steel, which then in the industrial process of its further processing and completion, quite simply cold formed and then filled accordingly.

This has not only the task of facilitating the actual welding process with such a flux-cored wire welding machine but also, above all, to positively and stabilizing influence the properties of the weld seam drawn by the craftsman.

Where to use Flux-Cored Welder

The flux-cored welding equipment presented here is mainly used for applications that have to be carried out outdoors and in the open air.

In practice, such a welding process, as it often has to be carried out and realized outdoors and in the open air, is always dependent in a very decisive way on the prevailing and encountered weather conditions on-site.

However, the wind is and always will be a striking and particularly significant disruptive factor for the welding process to be carried out and realized outdoors. In contrast to conventional and traditional forms and methods of arc welding, the welding process that can be carried out outdoors with the flux-cored wire welding device always proves to be particularly resistant and independent of the possible influence of the wind.

Therefore, such a modern flux-cored welding machine is today often preferably used and applied for such types of welding work that have to be carried out outdoors and professionally realized by the respective welder.

Here, the flux-cored wire welder can fully display its characteristic advantages and features and accordingly also bring them to bear. When welding outdoors and in the open air, even in gusts of wind, the flux-cored wire welder has always proved its worth in the past and present.

  • Gas-protected flux-cored wire

In MIG or MAG welding, the so-called flux-cored wire has, among other things, the important and for the success of the entire welding process so immensely essential and decisive task to fulfill and to realize, to form gases.

However, in contrast to many other types of corresponding flux cored wires used in technology today, the so-called gas-protected flux-cored wire explicitly has no gas formers inside it. In contrast, it only has arc stabilizers that are so important for the process.

A gas-protected cored wire also has the important material task of ensuring that slag can form explicitly on top of the freshly drawn welding wire.

In practice, this slag then always serves to protect the freshly drawn weld seam against corrosion and oxidation processes. In contrast to the full flux-cored wire, which consists entirely of round steel, a weld seam is then much more accurate and precise in practice with such a gas-protected flux-cored wire.

The welding process can therefore be significantly improved and optimized by the use of a gas-shielded cored wire, and the results achieved with this wire can be significantly improved.

When using such a modern gas-shielded cored wire, however, the additional and explicit supply of shielding gas to the welding device is once again absolutely necessary. However, this is no longer a problem in the practical use and application of such a gas-shielded cored wire.

Above all, however, due to the welding seams, which are considered to be excellent, that can be drawn and generated with the device, the technology proves to be quite outstandingly suitable for practical use.

  • Self-protecting filler wire

Another working and auxiliary tool that can be regularly used and applied in practice for so-called partially mechanized arc welding is the self-protecting flux-cored wire.

The self-protecting cored wire to be presented here in the following text contains in practice a true multitude of corresponding fillers and additives.

These include, above all, arc stabilizers, the gas formers already mentioned several times in the beginning, and, last but not least, various types of quite different alloying additives.

Therefore, the welding process that can be carried out using such a self-protecting flux-cored wire always has the very decisive feature that it can be carried out completely without the use of additional shielding gas in practice.

The core of the flux-cored wire contains a wealth of additives that are ideally suited to protect and preserve the freshly drawn weld from the dreaded effects of the earth’s atmosphere.

However, the formed gas bell proves to be comparatively unstable, which ultimately leads to the consequence that the generated arc is considered to be relatively unstable.

The use of self-protecting flux-cored wire in flux-cored welding equipment, therefore, requires the welder to have a maximum of individual practice and, above all, work experience.

In practice, the self-protecting flux-cored wire is used in connection with the flux-cored welding equipment to be characterized and described here, especially for thick steel girders and steel structures.

Self-protecting cored wire is absolutely unsuitable for use and application in the thin sheet sector due to its very characteristic and typical product properties, which then come into play during the welding process.

  • Metal powder welding rod

Another auxiliary and working material that can be used regularly in connection with a flux-cored welding machine is ultimately the so-called metal powder welding rod.

Here, too, the formation of a correspondingly massive so-called gas bell over the freshly drawn weld seam is comprehensively guaranteed and ensured, so that it can thus remain completely protected from the effects of the earth’s atmosphere and the corrosion processes that always result from this in practice.

An essential and quite typical characteristic of the metal powder welding wire to be presented here is that no slag is formed. However, it can often contain various types of alloying additions.

  • However, they can often contain various types of alloying additions.
  • However, since additional shielding gas can be explicitly added during the welding process, the metal powder welding rods are also fundamentally unsuitable for use in practice together with a flux-cored wire welding machine.
