Electrodes for welding of carbon and low alloy steels – choosing correctly.

To carry out welding, it is necessary to take into account the composition of the material being welded and its interaction with the welding electrode that is planned to be used for the work. All types of welding electrodes have their own characteristics and are suitable for specific types of metal.

Regarding the choice of welding electrode for the metal, it is worth noting that each grade of steel has its own types of electrodes with a similar composition.

In modern construction and manufacturing, various grades of carbon composition are most often used, therefore Electrodes for welding of carbon and low alloy steels are very frequently used when performing welding work.

How to choose the right electrodes for carbon steels?

If you are faced with a choice among all grades of electrodes for carbon steels, you must follow these rules:

It is necessary to correctly select the electrode for welding carbon and low alloy steels. All carbon steels contain iron and carbon in their composition. Other inclusions in the metal create difficulty when performing welding work.

Therefore, it is important to adhere to certain requirements so that the weld does not subsequently begin to crystallize and crack. A properly selected electrode for carbon steels will help solve these problems and prevent metal spatter during welding.

Popular grades of electrodes for welding carbon and low alloy steels.

The most widely used and commonly used electrodes for carbon steels are MP, ANO, UONI, and OZS. They allow for high productivity and are suitable for most steels that contain carbon in their composition.

These grades of welding electrodes have good technological performance indicators, prevent cracks, spatter, overheating of the metal, and boiling of the weld pool. For the most part, the electrodes contain: Carbon, Manganese, Silicon, Sulfur, Phosphorus.

The best in this series can be considered UONI 13/45 and UONI 13/55. These electrodes are intended for manual arc welding of particularly critical structures made of carbon and low alloy steels where increased ductility requirements are placed on the weld.

These welding electrodes are capable of preventing the problems that arise when welding carbon steels. UONI brand electrodes feature low metal spatter and contribute to the formation of a strong weld. After welding, the slag crust is easily removed, which significantly facilitates the work for the craftsman. They are more expensive because they use more costly chemical elements in their composition.

Welding electrodes of the MP brand (MP-3 and MP-3S) are cheaper than UONI and have good properties. They handle most ordinary metals, have good slag removal after welding, and feature low metal spatter during the welding process. They are suitable even for inexperienced welders without significant work experience.

OZS-12 welding electrodes allow welding to be performed at extremely low currents and are suitable for small-diameter welding electrodes. They are used for critical structures with resistance up to 490 MPa, including for concave welds.

Another commonly used type of electrode is the ANO-21 welding electrode. This brand is widespread among consumers due to its rutile coating. These electrodes are suitable for welding in domestic conditions when using a small inverter or transformer.
